7. TRAFFIC SIGNS

Many collisions and near crashes occur as a result of drivers who

ignore or fail to respond appropriately to traffic signs. It is essential

that the meaning of traffic signs be interpreted correctly. Signs

are classified according to their function: regulatory, warning and

information.

The easiest way to identify traffic signs is to learn to recognize

their shapes and colours. For safe driving, you must recognize and

obey traffic signs without hesitation.

A sign-conscious driver is a safe driver. Keep a constant look-out

for signs as you move your eyes in the field of view ahead of you.

7.1 Six Basic Sign Shapes Every Driver Must Know

Stop

The stop sign, a red octagon with white

lettering, means come to a full stop and be

sure the way is clear before proceeding.

Yield

Yield Right of Way signs are triangular and

have a red border on a white background.

A yield sign means you must reduce speed

when approaching an intersection. Give right

of way and stop if necessary if any other traffic is in, or closely

approaching, the intersection.

Regulatory

Regulatory signs are white rectangles or

squares with black or other coloured lettering.

These signs state the law, such as speed

limits, parking regulations and turning and

passing movements.

Warning

Warning signs are diamond shaped and are yellow or orange

with black letters or symbols. They warn of dangerous or unusual

conditions ahead, such as a curve, turn, dip or side road.

Railway Crossing

The crossbuck is the traditional symbol at roadway-railway crossings. Signs with a red reflective border on a white reflective background have replaced the older sign with “Railway Crossing” in black lettering.

School Zone

This five-side (pentagonal) sign indicates a school zone. When children are present in a school zone, slow down, watch for children and exercise extreme caution. The maximum speed permitted is 50 km/h unless otherwise posted. Regardless of the speed limit posted in a school area, your speed must be reasonable and prudent for existing conditions. 7.2 Standard Sign Colours

Each colour has a particular meaning.

Red – Stop or prohibition

Blue – General information or service road information

Green – Indicates traffic movement such as turns which are

permitted or directional guidance

Yellow – General warning danger/caution

Fluorescent Yellow – School zone and school crosswalk ahead

signs

White – Regulatory

Orange – Construction and maintenance warning

Brown – Off road facilities/motorist services

Parking Signs

Parking Signs Lane Designation Signs

These signs may be mounted above (or to the side of) the roadway. When mounted above, each sign is centred over the lane it controls. These signs indicate pedestrian movement, either at an intersection or mid-block. You must yield to pedestrians within the crosswalk. This lane must turn left This lane must turn right This lane left or through This lane right or through This lane left or right This lane all movements This lane through only Two-way left turn lane

7.4 Warning Signs

Warning signs are yellow and diamond shaped, and use symbols

instead of words. They give warning of some condition of the road

ahead that calls for special care on the part of the driver.

the most simple, direct method possible.
