2. ROAD MARKINGS

3. Why Road Markings?
• Bare roads will lead to total vehicular confusion.
Markings are painted on the road to direct, guide
and regulate the road user.
• Road markings include all lines patters, words
and colours applied on or attached to the road
surface or kerb, for the said purpose
• These markings promote road safety and ensure
smooth flow of traffic. Sometimes, road
markings are used to supplement the message
of road signs and other devices.

4. Have you observed such
Road Markings?

5. What Do These Colours Signify?
• WHITE is generally used for carriageway
(road) markings except those indicating
restrictions
• YELLOW markings are used to signify
RESTRICATIONS.
• WHITE or YELLOW together with BLACK
are used for kerb and object marking.

6. Do We Know What Different
Types of Road Markings Signify?
Lets Check and understand them
better!!!

7. CENTER LINES
• On undivided two-way roads, the centre
line separates the opposing streams of
traffic and facilitates their movements.
• The centre line can be a single broken
line, a single continuous solid line
(barrier line), a double solid line or a
combination of solid line and broken line.

8. Types of lines used to mark lanes.
• The Divided Lines visible in the pictures above are called
Lane Lines.
• Single and double solid lines, whether white or yellow,
must not be crossed or even straddled.
• They should be treated as a wall on the road .

9. Double Lines.
• Single and double solid lines, whether white or yellow,
must not be crossed or even straddled.
• Double Continuous lines are also used where visibility is
restricted in both directions.
• Neither stream of traffic is allowed to cross the lines.
• The Double Continuous Lines can be both in WHITE or
YELLOW

10. Combination Lines
• On a road with two centre lines, of which one is solid and
the other broken, the solid line has significance only it it
is on the left side of the combination as viewed by the
driver.
• In such a case, the driver must be careful not to cross or
straddle the centre line.
• If the line on your side is broken, you may cross or
straddle it.
OverTake - but only if it is safe to do so.
• If the line on your side is continuous you must not
cross or straddle it.

11. Stop Line.
• A stop line is a single solid transverse line painted before
the intersecting edge of the road junction/ intersection.
• This line indicates where you are required to stop when
directed by traffic officer, traffic light of stop sign.
• Where a pedestrian crossing is provided, the stop line is
marked before the pedestrian crossing.

12. Give Way Line
• The give way line is usually a double dotted line marked
transversely at junctions.
• These lines are generally supplemented by a reverse
triangle give way sign painted on the road surface before
the dotted lines or by a road sign installed beside the
marking.
• Give way to traffic on the main approaching road.

13. Border Edge Line
• These are continuous lines at the edge of the
carriageway and mark the limits of the main
carriageway upto which a driver can safely
venture.

14. Parking Prohibited Lines
• A solid continuous yellow line painted on the
kerb or edge of the carriageway along with a
"No-parking" sign indicates the extent of no-
parking area.

15. YELLOW BOX JUNCTION
• These are yellow crossed diagonal lines
within the box.
• The vehicles should cross it only if they have
a clear space available ahead of the yellow
box.
• In this marked area vehicles must not stop
even briefly.

16. Pedestrian Crossing
• These are alternate black and white stripes painted
parallel to the road generally known as zebra crossing.
• Pedestrians must cross only at the point where these
lines are provided and when the signal is in their favour
at controlled crossings.
• You must stop and give way to pedestrians at these
crossings.
• Pedestrian crossings are marked to facilitate and give
the right of way to pedestrians.
