3. Traffic signs that regulate roadways to help drivers use
the roadways in an orderly fashion.
Regulatory signs use the following shapes:
Cricular, octagon , equilateral triangle with the point
down and vertical rectangle
The colors used for regulatory signs are red and
white .
18. This signs are used to warn drivers and allow adequate time for
a cautious response.
This signs are often diamond-shaped , pentagon-shaped
and equilateral triangle pointing upward.
The colors used for warning signs are yellow, red and black
because these are brighter color makes these signs more visible
in foggy or rainy conditions.
40. Informative traffic signs, also known as guide signs.
Informative signs are green, blue or white.
Informative signs are often horizontally rectangular,
while roadway designation signs can be shaped like
shields or rectangles.
48. Temporary signs that road work crews post in
construction zones to warn of danger or regulate .
This traffic are orange, and often in the shape of a
diamond or horizontal rectangle.
53. INTRODUCTION
“Code of Practise for Road Markings”, IRC;35-1970
was published by the Indian Roads Congress (IRC) in
1970.
This code revised and the modified draft was
approved by the executive committee in its meeting
held on 19.4.1995.
Road Markings perform an import function of
guiding and controlling traffic on a highway.
54. SCOPE
The object of this Code of Practice is to establish
a uniform system for road marking in India with
paints/thermoplastic material.
Recommendations of the code are applicable to
all categories of roads both in rural and urban
areas.
55. DEFINITION
Road markings are defined as lines, patterns,
words or other devices, except signs, set into
applied or attached to the carriageway or kerbs
or to objects within or adjacent to the
carriageway, for controlling, warning, guiding and
informing the users.
56. AUTHORITY
A uniform set of markings applicable throughout the
country.
Road markings on a particular stretch of public road
should be decided by Road Authorities in
consultation with Police, wherever felt necessary.
Pavement and kerb markings being exclusively within
the boundaries of public road should be installed by
public authority.
57. MATERIALS
Paints used for road markings should conform to IS :
164-1981 “Specifications for ready mixed paints for
road markings”.
Improved night visibility in Road Markings is obtained
by the use of minute glass beads.

59. CLASSIFICATION OF MARKINGS
The road markings may be classified as:
1. Carriageway Markings
Longitudinal markings
• Centre lines
• Traffic lanes
• No passing zones
• Warning lines
• Border of edge lines
• Bus lane markings
• Cycle lane markings
60. Markings on intersections
Stop lines
Give way lines
Pedestrian Crossings
Cyclist Crossing
Marking on approaches to intersections
Marking on speed change lanes
Direction arrows
Protected right turn lanes
Marking on rotaries
Box markings
Continuity lines
Markings at hazardous locations
Carriageway width transition
Road-Rail level crossings
Check Barriers
61. Markings for parking
Parking space limit
Parking restriction
Bus stops
Word Messages
Stop
Slow
Bus
Keep Clear
School
Exit Only
2. Object Markings
Objects within the carriage way
Object adjacent to the carriageway
Marking on kerbs
65. OBJECT MARKINGS ARE APPLIED TO
TRAFFIC ISLANDS, CULVERT
HEADWALLS, PIERS, ABUTMENTS,ETC
66. Kerbs
• A curb or kerb is the edge where
a raised pavement / sidewalk
/footpath, road median, or road
shoulder meets an unraised
street or other roadway. Typically
made from concrete, asphalt or
long stones (often granite), the
purpose is twofold: first as a
gutter for proper drainage of the
roadway, and second for safety, to
prevent motorists from driving
onto the shoulder, median,
sidewalk or pavement.
67.
68. ABUTMENT
An abutment is, generally, the point
where two structures or objects
meet.
Specifically, an abutment may be:
• the part of a structure that supports
an arch.
• the tooth or teeth that support a
fixed or removable bridge.
• the part of an implant that acts as a
connection between the implant and
the crown.
69. TRAFFIC ISLAND
A traffic island is a solid or
painted object in a road that
channelizes traffic. It can also be a
narrow strip of island between
roads that intersect at an acute
angle. If the island uses road
markings only, without raised
kerbs or other physical
obstructions, it is called a painted
island.
70. General principles of longitudinal
pavement markings
• Solid lines are restrictive in nature & it is an
offence to cross or straddle such a line.
• Broken lines are restrictive in character &
vehicles can cross such a line provided this can
be done with safety.
• When a combination of a solid & broken lines
is used, a vehicle should not cross the
continuous lines adjacent to
• Double lines indicate maximum restriction.
