INTRODUCTION
This manual specifies the lines, patterns, symbols, letters and
numerals, pavement bars and markers used in or on roads, road
related areas and other places including kerbs, for the purpose of
regulating, guiding and warning road users, and provides guidelines
for appropriate use.
TYPES OF MARKINGS
This Section describes the types of markings including paint
substitutes, pavement bars, raised pavement markers and coloured
and/or textured surfaces.
A
B
It details the actual dimensions and other specification attributes of
markings which need not be shown on traffic control and road design
drawings.
DESIGN GUIDE
This section describes the requirements for the correct and consistent
use of pavement markings in South Australia.
C
It is intended that the section provide specific diagrammatic examples
of the application of markings and where necessary explain to the
designer the reasons why certain treatments are used. It also
provides references to the Code of Technical Requirements for the
Legal Use of Traffic Control Device (The Code), Australian Standards,
Austroads and Department for Transport Energy and Infrastucture
(DPTI) Operational Instructions.
All road authorities including their consultants and contractors are
required to conform to this manual.

PART A
Introduction
1.0 Scope
This manual specifies the lines, patterns, symbols, letters and numerals, pavement bars and
markers used in or on roads, road related areas and other places including kerbs, for the
purpose of regulating, guiding and warning road users, and provides guidelines for
appropriate use.
2.0 Legal Requirements
An "Instrument of General Approval" has been issued by the Minister for Transport to
Councils and the Commissioner of Highways (and some other authorities) to use traffic
control devices which includes pavement markings. The conditions of this general approval,
which are required by law under the Road Traffic Act are contained in Part 2 - Code of
Technical Requirements for the Legal Use of Traffic Control Devices (The Code) which forms
part of ‘The Legal and technical responsibilities for Traffic Control Devices’. One of the
conditions of general approval is the requirement that the design, installation, alteration and
removal of pavement markings be in accordance with the Code.
This manual has been developed to conform with the Code and takes into consideration the
relevant Australian Road Rules, Australian Standards, Austroads guidelines and Department
of Planning Transport and Infrastructure Operational Instructions.
Pavement markings not conforming to this Manual and the Code, such as innovative or nonstandard treatments are not authorised to be used under the Instrument of General Approval
issued by the Minister. Authorisation for such treatments may only be given by the Manager,
Traffic and Access Standards Section, Department of Planning Transport and Infrastructure
(DPTI), acting as the Minister’s delegate.
3.0 General Attributes
3.1 Purpose
A system of clear, effective and consistently applied pavement markings is essential for
the proper regulations, warning and guidance of drivers, cyclists, pedestrians and other
road users.
Pavement Markings may guide traffic or give advance warning or may impose
restrictions which are supported by the Road Traffic Act. They may act as a
supplement to other traffic control devices or may be used alone to convey certain
regulations, warnings and guidance.
It is therefore important to ensure that the use of the markings conforms with the legal
requirement mentioned above before they are approved, installed, altered or removed
to avoid possible conflict or confusion, legal or otherwise.
3.2 Removal of Markings
Where traffic conditions are altered and the existing pavement markings no longer
apply it is essential that those markings be removed or obliterated. It is important that
the end result of removing markings does not leave an impression of the marking on
the road surface which may otherwise be interpreted as a marking in certain light
and/or weather conditions.
In rare cases, redundant pavement markings may be allowed to fade but only when
these markings cannot be misinterpreted or otherwise create a confusing message to
the road user which may create a safety hazard.
A-1
Introduction
3.3 Limitations
Pavement markings have the following limitations:
(a) They may not be clearly visible if the road is wet or dusty, for example near an
edge of a median.
(b) They are subject to traffic wear and usually require frequent maintenance.
(c) They can be obscured by traffic.
(d) Their effect on skid resistance requires careful choice of materials and precludes
the use of large marked surface areas.
(e) They cannot be applied to unsealed roads.
In spite of these limitations they have the advantage under favourable conditions of
conveying information to the driver without diverting attention from the road.
3.4 Reflectorisation
All longitudinal lines except zig zag markings shall be reflectorised.
3.5 Anti-Skid Treatment
An anti-skid treatment shall be applied to all markings other than longitudinal lines.
3.6 Materials
Road pavements may be marked with paint, thermoplastics, pre-cut sheeting, raised
pavement markers (retro-reflective, non reflective or illuminated) or pavement bars.
3.7 Colours
For all traffic control purposes pavement markings shall be white, yellow or blue. Yellow
shall be used on pavement bars and to define tram only lanes and areas where
parking/stopping restrictions apply. Blue is used for disability access. Raised pavement
markers may be white, red or yellow.
Black paint may be used in the gaps and around the edges of pavement markings to
heighten contrast where a light coloured pavement does not allow adequate marking
definition to be obtained. Where this is being considered advice should first be sought
from Manager, Traffic and Access Standards Section, DPTI.
In situations such as community events on closed roads light blue coloured pavement
markings (known as honour lines) may be used to define pedestrian boundaries.
These markings are not considered traffic control devices but should be removed after
the event, to ensure road users are not confused by the markings.
3.8 Distinctive Pavement Colours
There is a trend by road authorities to use distinctive coloured pavements to highlight
the road surface in a visual, tactile or audible manner. Such treatments may
supplement traffic control devices (e.g. bus lanes, bicycle lanes and islands) or they
may be aesthetic devices to supplement streetscape designs (e.g. intersection
threshold paving treatments). For commonly used distinctive coloured pavement areas
used in South Australia, refer to Part A 2.15.
3.9 Off Street Parking Areas
AS 2890.1 and AS 2890.6 are used in South Australia for off street car parking
pavement markings.

railway crossings and ferries. No gaps should be left for driveways or other accesses, only side roads.
Where the road speed limit is >80 km/h and :
- Double two-way barrier lines are justified, then double two-way barrier lines shall be used. Gaps should be left in linemarking
for driveways, or other accesses and side roads.
- Double one-way barrier lines are justified, then double one-way barrier lines shall continue across driveways and other
access but gaps shall be left for side roads.
- Double two-way barrier lines are justified on the approaches to railway crossings and ferries, an enhanced single barrier line
shall be used. Gaps should not be left for driveways or other accesses, only side roads.

** Note: The application of Standard Continuous and Enhanced edgelines should be
consistent over the entire length of the road. There must not be short lengths of change
in edgeline style less than 1km.
Should there be just a few kilometres of sealed shoulder >0.5 metres in the middle of a
route (between townships) with a sealed shoulder width <0.5 metres, the standard
continuous edgeline must be applied to the length with the sealed shoulder >0.5 metres
with a transition to the existing standard broken edgeline as shown in Part B 2.18.4.

Gaps shall be provided in double two way barrier lines and shall generally be 10m wide and centrally placed at the
intersecting centre point of the side road.
Where barrier lines are required for vertical or horizontal alignment sight restrictions take precedence over standard
rural two lane, two way road intersection treatments.
2.17.2 Property accesses
Gaps should not generally be provided in double two way barrier lines. Leaving a gap allows a driver to legally enter
and leave the road as well as U-turns at a place where there may be a restricted sight distance due to horizontal or
vertical curves. A gap may only be provided where a survey determines that sufficient sight distance is available to
safely allow all movements.
Where provided the gap shall generally be 5m. The gap may be increased at wider accesses or where the turning
vehicle envelope would otherwise cross the double two way barrier lines.

3.0 TRAFFIC CONTROL DRAWINGS AND DESIGN LAYOUTS
3.1 LONGITUDINAL LINES
Longitudinal lines shall be shown on all traffic control drawings. This includes edgelines and
outlines.
Dimensions to kerbs shall be to the kerb face. Dimensions to longitudinal lines (other than zig
zag school zone markings ) shall be to the centre of the line. Dimensions of barrier lines shall
be to the centre of the combination of the two parallel lines.
3.2 TRANSVERSE LINES
Transverse lines shall be shown on all traffic control drawings. Dimensions shall be clearly
shown to either the leading or trailing face of all transverse lines, except pedestrian cross walk
lines. Pedestrian crosswalk lines shall be dimensioned to the centre of the line.
3.3.1 Parking Control Edgelines
All parking control lines (where used) shall be shown on traffic control drawings.
Parking control edge lines shall be marked in a consistent alignment parallel to and
approximately 400mm from the kerb or edge of seal.
3.3.2 Parking Space Outlines
Parking space outlines shall be shown and dimensioned on traffic control drawings.
Diagonal stripes and chevron marking shall be shown on traffic control drawings.
3.5 ARROWS
All arrows shall be shown on traffic control drawings and may be dimensioned longitudinally.
Arrows shall be located centrally within the lane width as shown in Part B 2.5.
3.6 MESSAGES AND SYMBOLS
All messages and symbols shall be shown and the longitudinal spacing dimensioned
longitudinally on traffic control drawings.
Messages and symbols shall be located centrally within the lane such that a minimum of
150mm gap is maintained between the edge of the message or symbol and the centre of any
adjacent longitudinal line or to the edge of seal. Spacing between letters to form commonly
used words are shown in Part B 2.6.2.
Bicycle symbols shall be located approximately 100mm from the bicycle lane line adjacent to
the traffic lane. Where the bicycle lane is less than 1.4 metres wide it will be necessary to
reduce the width of the symbol. This will be achieved by masking part of the rear wheel to
preserve the 100mm gap between the edge of the symbol and the centre of lane line.
Symbols on paths shall be located centrally within the designated area of travel i.e. between the
left edge of the path and the separation line. Examples for both symbols and messages on
paths is shown in Part C 2.19.

2.0 GENERAL TREATMENTS
References
General treatments are considered those that apply in all urban built up areas. These include
local residential roads, collector roads, arterial roads and expressway type roads in or near
cities and townships. They may include roads of any speed environment.
2.1 DIVIDING LINES
There is no traffic volume warrant for the provision of dividing lines on urban roads in South
Australia. It is important for designers to remember that the use of single continuous dividing
line prohibits certain crossing movements, including U turns, but does not prohibit entering or
leaving the road. U turns should generally not be restricted by the use a single continuous lines
unless site distance is poor or special facilities have been provided to satisfy U turn demand
within the section of road.
ARR 132, 134
AS1742.2 Section 5
GTM Part 10
OI 2.15
OI 2.27
OI 2.40
Any assessment for the need for dividing lines should take the following into consideration:
l
All ‘arterial’ roads shall be provided with dividing lines in urban areas, and shall be
augmented with RRPM’s.
l
All ‘collector’ roads should be provided with dividing lines.
l
Local roads may be provided with dividing lines. Installing dividing lines on narrow roads
may have implications for parking.
l
Where provided between major intersections dividing lines should be broken, and shall be
standard width for two lane roads and enhanced for multi lane roads.
l
Where provided on minor or local roads at intersections, short sections of continuous
dividing lines may be provided (see intersection examples in Part B 2.13.8, 2.13.9 and Part
C 3.7).
l
Double barrier lines, i.e. multiple lines consisting of combinations of broken and continuous
lines or double continuous lines, are not used on urban roads.
l
Broken dividing lines on arterial roads continue through minor road intersections.
l
On any road, a break is provided in continuous dividing lines through intersections (see
Part B 2.13.9 for example).
Dividing lines are not normally necessary on minor road approaches to major roads. However
there may be situations where such lines could provide additional guidance to road users.
Such cases include :
- Wide side roads
- Multi lane side roads
- High volumes of right turn movements into and/or from minor road
Dividing lines should not be provided on minor road approaches where right turn and through
movements are prevented or prohibited from the minor road.
Dividing lines should always be provided on minor road approaches that have give way or stop
lines (also see Part C 2.12).

2.2 BARRIER LINES
Double one way barrier lines are used at Railway Crossings and Ferries in both rural and
urban areas where the speed limit is >80km/h to prohibit overtaking on the approached side.
A single continuous barrier line should be used where the speed limit is <70km/h or as an
alternative to permit traffic to cross the line to enter or leave the road. Where single
continuous barrier line is used, it shall be standard width on roads <70km/h and enhanced
on roads >80km/h.
ARR 132, 134
AS1742.2 Section 5
AS1742.7 Section 3
GTM Part 10
OI 2.15
OI 2.40
OI 7.1
Generally single continuous lines should be used instead of double barrier lines (one-way or
two- way) in urban and low speed rural areas (also see Part B 2.1.2).
There is a temptation to use double barrier lines (double one-way or double two-way) to
control vehicle movements. However experience has shown that such treatments are
generally too passive in nature. Where it is considered necessary to prohibit all crossing
movements (for road safety) then preference should be given to physical controls e.g. raised
medians and islands, that are self regulating and do not rely on police enforcement to be
effective.
For further information on the use of barrier lines on rural roads refer to Part C 3.4.
C-3
Design Guide
References
Diagonal stripes and chevron markings are used to augment and highlight pavement
marking treatments. They often have legal significance under the ARR. They take the form
of chevrons when used to indicate that drivers, travelling in the same direction may pass
either side of the treated area or as diagonal stripes where the treatments separate
opposing traffic flows. Refer to Part B 2.4 for detailed layout of stripes.
ARR 88, 138 and 197
AS1742.2 Section 5
GRD Part 4A
Spacing between diagonal stripes at low speed turns is generally 6m. The spacing for
diagonal stripes and chevron markings is generally 6m on roads <70km/h, 12m on roads
>80km/h and 24m or 48m on freeways/expressways.
Diagonal stripes shall be placed at 45 degrees to the direction of travel whether straight or
curved and shall be at 45 degrees to the centre line of the divergence where drivers travel
on both sides of the markings.
While not exclusive, below are examples of diagonal treatments.

The use of diagonal stripes is discouraged on left turn treatments,
where the left turn driver has priority. Stripes are a passive treatment
and in this location are usually driven over regulary, requiring additional
maintenance. They can also be a slip hazard with differential skid
resistance between the painted area and the pavement.
kerb
*Nominal spacing between stripes is 6 metres but may be varied. For rural treatments the
spacing may be increased depending on the radius of the curve. Where the section to be
striped is short it is preferable to provide stripes closer together (as close as 3 metres) to
ensure the stripes provide the desired effect of discouraging traffic from driving on the area.

2.3.2 Flush medians
References
Flush medians may separate lanes dividing opposing traffic streams, while allowing access
to and from the road or entrance to a turning lane.

It should be noted that unlike raised medians, flush medians do not provide physical control
of traffic movements nor do they have the advantages of being clearly visible, especially at
night and in wet weather.

2.3.3 Corner islands
The use of very small corner islands (less than 3m sides) should be avoided. Such islands
cause confusion to drivers regarding give way responsibilities when turning at intersections.
Chevrons and diagonal stripes may be used between the outline and the kerb of a raised
island where better turning control is required. However they should only be augmented
with diagonal stripes where the distance between the kerb and outline is greater than 1.0m.

2.4 DIVERGE AND MERGE TAPER TREATMENTS
2.4.1 Diverge taper treatments
It is often necessary to move traffic laterally across a section of road without merging lanes.
Examples include divergence of traffic lanes to avoid pedestrian refuges, on street parking
areas and at the start of median sections.
C
It is preferable to provide as long a divergence length as possible, especially where two or
more adjacent lanes must diverge. The following diverge calculation provides a minimum
length. However, experience has shown that greater lengths should be provided whenever
possible. For example, extra taper length is important for pedestrian refuge situations to
provide additional protection for pedestrians and to avoid constant damage to signs and
pedestrians hand rails.

2.5 RAISED PAVEMENT MARKERS
Broken and continuous lines may be augmented with retroreflective raised pavement markers
(RRPMs).
Standard spacing is 12m on lit and 24m on unlit roads.
As a minimum on arterial roads, RRPMs shall be provided on all dividing lines in urban areas
and should be provided in rural areas. RRPMs should also be provided on lane lines, special
purpose lane lines and flush island outlines.
RRPMs enhance longitudinal lines to such an extent that they discourage crossing
movements. For this reason RRPMs shall not be used on continuity lines except in
circumstances shown.
RRPMs may be used on collector and local roads if additional delineation treatment is
considered necessary.
For the use of non-reflective pavement markers through intersections, refer to Part C 2.17.6.
C-10
Design Guide
2.5.1.Continuity lines
References
Generally RRPMs are not required on continuity lines. However, in some rare cases they may
be required to provide guidance .eg
- On tapers where traffic is required to deviate from their path eg. trapped lane situation.
- On long lengths of curvilinear continuity lines.
C
Note:
- RRPMs shall not be used on continuity lines in merging situations.
- Where used, spacing shall be generally the same as that applied to lane lines i.e. 24m
on unlit roads, 12m on lit roads.
12m
where RRPMs on continuity lines are used, it must
be shown / indicated on the design drawings.
2.5.2 Bicycle lanes
The provision of RRPMs can be hazardous to cyclist’s when placed adjacent bicycle lane
lines. This is particularly the case for part-time bicycle lanes when cyclist’s are required to ride
around parked cars outside bicycle lane operating times. Therefore it is recommended that
RRPMs not be located adjacent to or near part-time bicycle lane lines. It may also be
appropriate to not install RRPMs on full-time bicycle lanes in areas where cyclists are required
to ride around buses and other vehicles legitimately stopped on the road.

2.6 LANE LINES
References
Lane lines divide two or more lines of traffic travelling in the same direction and shall be
provided on roads where traffic is expected to travel in more than one lane.
ARR 146
AS1742.2 Section 5
Lanes in urban areas should not be marked on a road where it would result in lane widths of
less than 3.0m.
Where kerbside lanes are designed to be shared with cyclists, the minimum lane width shall
be 3.7m
Lane lines are normally standard broken. However, continuous lane lines may be required
between exclusive through and exclusive turn lanes on approaches to intersections (see Part
C 2.7). They may also be used to restrict lane changing mid-block.
Lane lines should be continued through minor road intersections.
At a lane drop, the lane line should cease before the taper commences. This distance is
shown in the table in Part C 2.4.2.
For lane lines on the approach to signalised intersections see Part C 2.17.5.
For the use of continuity lines as lane lines (including the length of continuous line) see

Lane lines on the approach to a multilane roundabout are positioned as they would be for

2.7 CONTINUITY LINES
Continuity lines generally provide longitudinal ‘continuity’ to traffic along lengths of road
where lane lines or other longitudinal lines either cannot or should not be provided. They are
used to substitute lane, dividing or edgelines where it is intended that the line be crossed.
Where they are used in lieu of a lane or dividing line it is important to remember that they
may continue to have the same legal effect in regard to traffic movements.
Examples of continuity lines include :
l
To provide continuity at very wide straight openings across side roads or other entry and
exit points along a road or across those openings that are subject to significant vertical or
horizontal changes. Continuity lines should only be provided for such situations where it is
likely that through traffic would otherwise loose continuity of travel (see Part C 2.5.1 for
example).
l
At the start and end of auxiliary and special purpose lanes to indicate the section of road
that should be crossed to access or exit the auxiliary lane.
l
Across side roads and other sections of road to indicate the continuance of bicycle lanes.
l
Across median openings where the median is greater than 2 metres in width.

Generally parking control markings, such as lines, T’s and L’s used to delineate parking
spaces are white.
Clearways, both part time and full time shall not be marked with edgelines.
Full time parking restriction lines i.e. unbroken yellow lines, may be used to designate No
Stopping areas (with or without sign posting), but shall not be used to designate No Stopping
areas already covered in the Road Rules i.e. driveways, corners of road intersections, bus
stops, post boxes and fire hydrants.
If yellow parking control lines are used along a section of road, they shall not be marked
through bus stops. The lines shall also not be marked 3m each side of a post box or 1m

2.12 KERB EXTENSION MARKINGS
Kerb extensions (formerly known as protuberances) are used to reduce road widths,
especially in pedestrian crossing locations. They also provide traffic calming qualities to a
road by removing parking from the through traffic.
As the name suggests, kerb extensions should preferably consist of raised areas bordered
by semi mountable median type kerbing. However, they may also consist of pavement
markings designated by outline markings with diagonal stripes, and pavement bars and/or
RRPMs.
Kerb extensions may also be used to physically control the movement of vehicles, such as a
traffic divergence on a road section or to create a high angle entry to the main road.

2.13 STANDARD INTERSECTIONS (Local Roads)
Local or minor roads need not to be line marked. However, where they are, it is preferred to
provide a single dividing line to the extent of the limit of the No Stopping restriction from the
intersection (only) on the road with priority.
The controlled road approaches i.e. the road under Give Way or Stop sign control must be
provided with a give way or stop line. The provision of a dividing line from the give way or
stop line is preferred.
The dividing line would not normally extend beyond 10m from the kerb alignment of the
intersecting road. This length of line matches the road rule which prohibits stopping within
10m of an intersecting road.

more then one lane, lane lines should be provided. In these cases, the lane line should
commence 300mm from the prolongation of the main road kerb line. At least three line
segments are preferred.
For multi-lane minor roads approaching a major road, lane lines should cease with a full line
segment at 300mm back from the prolongation of the main road kerb line. Where a stop or
give way line exists, the full line segment should cease.
Where lane use discipline is a problem, pavement arrows should be provided.

2.17.3 Turn lines
Turn lines may be used within signalised intersections to indicate the proper course to be
followed by turning vehicles. They shall always be used within an intersection where there
is more than one turning lane for turns in a particular direction. They are not required when
the path to be followed is obvious to drivers under all conditions.
AS1742.14
Where opposing right-turn movements operate in the same phase, care must be taken with
positioning turn lines so that sufficient gap is left between opposing turning traffic.
Austroads turning path templates or recognised equivalent should be used for turn lines. It
is suggested that a gap of 1.2 to 2.0m is provided between the turning vehicle envelopes.
At major urban intersections with double right-turn lanes from opposite directions, it is
necessary to select the design vehicles for the turns, e.g. car and semi-trailer from both
directions.
Turn lines should not be carried through pedestrian crosswalks but may continue after to
continue guidance.
Turn lines location shall be determined using design turning envelope as a guide, however
each location will be different depending on, for example, approach road angles, number of
turn lanes and/or phase sequence. Where multi-turn lanes exist adequate separation shall
be provided between each adjacent design turning envelope.
Turn lines can be designed and depicted using turn line design strings.

2.17.4 Pavement arrows
Intersection pavement arrows may be provided in lanes to indicate the direction in which a
driver is legally obliged to travel through the intersection. They should only be used in lanes
from which the movements differ from the road rules. e.g. The road rules allow drivers to
turn left or travel through an intersection from the left lane. If these movements are to be
permitted within the intersection, the pavement arrow should not be provided. For simplicity,
use of Intersection Pavement Arrows table (page C-38) shows the movements for which
arrows shall be provided.
C
Intersection pavement arrows shall not be used to indicate a turn where the turn is
restricted during certain hours of the day.
When used, a minimum of 3 arrows should be provided in a traffic lane on the approach to
traffic signals. The arrow closest to the intersection shall be provided 6m from the stop line
or from the tangent point of the curve for a left turn lane. Subsequent arrows should
normally be provided at as close to 30m spacing as possible (tail to tail). However, to
ensure three arrows are provided, spacing may be reduced down to a minimum of 15m.
The last arrow shall be provided at a point where the full lane width is developed. For very
short lanes where three arrows cannot be provided (at 15m spacing) the number of arrows
may be reduced.

References
On the immediate approaches to traffic signals, the use of lane lines is essential where
the approach width will accommodate two or more traffic streams.
On the approach lane lines should cease with a full line segment at the stop line. This
may require a shorter gap segment, or a longer line segment.
C
On exits to intersections where pedestrian crosswalks exist, lane lines should start as
close as practicable (but not closer than 300mm) to the crosswalk.
For zip merges on the exit to intersections, refer to Part C 2.4.2.
For the use of continuity lines as lane lines, refer to Part C 2.7.

2.17.6 Non-reflective raised pavement markers
Vehicles my require guidance through intersections by the placement of Non-Reflective
Raised Pavement Markers (NRPM) within the intersection for non-turning traffic.
Treatment is normally applicable only to wide signalized intersections on multilane roads.
NRPM must be placed such that they do not interfere with the alignment of the cross
movement lanes.
References
AS1742.2 Section 5
Typical situations are:
Lanes on opposite sides of the intersection offset by half a lane width or more.
Drivers required to steer a curved course through the intersection.

difficult to follow.

l
Where the pedestrian refuge divides opposing traffic movements unidirectional yellow
RRPMs shall be provided at 6.0m spacings. White RRPMs shall be provided at the same
spacing where the refuge separates traffic travelling in the same direction.
Pedestrian refuges are either short lengths of raised medians used on roads for the sole
purpose of providing a staging area for pedestrians crossing the road or are long lengths of
median through which ‘cut outs’ or ‘walkthroughs’ may be provided.

2.24 FLOODWAYS AND CAUSEWAYS
Floodways and causeways are sections of road that are subject to flooding. When water is
over the roadways delineation is reduced because the edgelines and particularly the
standard dividing line (3m line, 9m gap) is very difficult to see through the water. However, it
is important not to unreasonably restrict traffic movement by providing an continuous dividing
line.
C
To increase delineation qualities of the dividing line while still allowing the line to be crossed,
a special purpose broken dividing line ( i.e. 9m line, 3m gap) shall be used across the
section of road regularly subject to flooding.

3.0 RURAL TREATMENTS
References
This section details the pavement marking differences between the general or urban
treatments and those in rural areas. In cases other than those listed below, treatments should
be the same for both built up urban and rural situations.
3.1 DIVIDED RURAL ROADS
Although most of the design details for treatments between intersections in this section relate
to undivided roads, the same principles, with the exception of dividing lines, should be applied
for divided roads.
3.2 MULTI-LANE UNDIVIDED RURAL ROADS
Multi-lane undivided roads shall not be used in high speed rural environments with the
exception of specific treatments such as overtaking lanes, CHR and CHL intersection
treatments.
3.3 DIVIDING LINES ON RURAL ROADS
Dividing lines shall be installed in accordance with AS1742.2 other than at isolated
intersections treatments. The use of single continuous barrier lines as dividing lines are not
recommended in high speed rural environments. Although such lines prohibit certain crossing
movements, including u-turns, they do not prohibit entering or leaving the road (see Barrier
Lines on Rural Roads).
AS1742.2 Section 5
Any assessment for the need for dividing lines needs to consider the following:
l
All rural ‘arterial’ roads shall be provided with dividing lines and should be augmented with
RRPM’s.
l
All rural ‘collector’ roads should be provided with dividing lines.
l
Local rural roads may be provided with dividing lines. Installing dividing lines on narrow
roads may have implications for parking.
l
Where provided between major rural intersections dividing lines should be broken, and
shall be standard width for 2 lane roads and enhanced for multi lane roads.
l
Where provided on minor or local rural roads at intersections, short sections of single
continuous barrier line may be provided.
l
Dividing lines on rural arterial roads through minor road intersections are generally broken
(see Part C 3.8 Standard Rural Intersections).
3.4 BARRIER LINES ON RURAL ROADS
A single continuous barrier line should be used through rural townships as an alternative to
double two-way barrier lines. This allows the line to be crossed by traffic entering or leaving
the road.
Barrier lines on high speed rural roads shall only consist of double lines, either ‘Double One
Way Barriers’ or ‘Double Two Way Barriers’ to create ‘No Overtaking Zones’ and shall be
restricted to locations with either horizontal or vertical sight restrictions or both and only be
determined in accordance with AS1742.2.
Double barrier lines, one way or two way, are not generally used in SA to prohibit overtaking
at isolated locations unless there are sight restrictions which meet requirements for such
lines.
The only exceptions to the above requirement include:
l
l
l
Railway level crossings in accordance with Australian Standards Manual of Uniform Traffic
Control Devices (AS1742).
Overtaking lanes in accordance with this document and Operational Instruction 2.15
Ferry approaches in accordance with Australian Standards Manual of Uniform Traffic
Control Devices.

3.5 LANE LINES ON RURAL ROADS
References
Lane lines i.e. lines dividing lanes of the same direction traffic, must be provided on roads
where traffic is expected to travel in more than one line of traffic.
Lanes should not be marked on a rural road where it would result in lane widths of less than
3.2 metres. Restricted access routes may require greater lane widths.
C
Lane lines are normally standard broken. However, unbroken lane lines may be used
between exclusive through and exclusive turn lanes on approaches to intersections.
Lane lines on rural roads should be continued through minor road intersections.
All multi lane divided rural roads shall be provided with enhanced edgelines and outlines.

3.6 EDGELINES ON RURAL ROADS
Edgelines are provided on most rural arterial roads. They provide a clear definition of the
lane and discourage traffic from travelling on shoulders.
AS1742.2 Section 4
AS1742.2 Section 5
GRD Part 3
They are particularly effective at night.
Edgelines shall be provided on all rural roads to ensure the desirable alne width does not
exceed 3.5 metres.
Practices regarding lane and sealed shoulder widths including the issues relating to
pavement depth, should be considered before providing an edgeline.
Part C 3.6.1 and 3.6.2 show best practice in regard to installation of dividing lines and
edgelines.
Part C 3.6.3 and 3.6.4 indicates a required treatment.
