Traffic signs give you important information about the law, warn you about dangerous conditions and help you find your way. Signs use different symbols, colours and shapes for easy identification.

Here are some of the many signs you will see on Ontario roads:

A stop sign is eight-sided and has a red background with white letters. It means you must come to a complete stop. Stop at the stop line if it is marked on the pavement. If there is no stop line, stop at the crosswalk. If there is no crosswalk, stop at the edge of the sidewalk. If there is no sidewalk, stop at the edge of the inter­section. Wait until the way is clear before entering the intersection.
