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.
A school zone sign is five-sided and has a fluorescent yellow/green background with black symbols. It warns that you are coming to a school zone. Slow down, drive with extra caution and watch for children.
A railway crossing sign is X-shaped with a white background and red outline. It warns that railway tracks cross the road. Watch for this sign. Slow down and look both ways for trains. Be prepared to stop.
A yield sign is a triangle with a white background and a red border. It means you must let traffic in the intersection or close to it go first. Stop if necessary and go only when the way is clear.
There are four other kinds of signs: regulatory, warning, temporary conditions and information and direction.
These signs give a direction that must be obeyed. They are usually rectangular or square with a white or black background and black, white or coloured letters. A sign with a green circle means you may or must do the activity shown inside the ring. A red circle with a line through it means the activity shown is not allowed.
Here are some common regulatory signs:

Information and direction signs
These signs tell you about distances and destinations. They are usually rectangular with a green background and white letters. Other signs with different colours guide you to facilities, services and attractions.
Here are some common information and direction signs:
Shows directions to nearby towns and cities.
Shows the distances in kilometres to towns and cities on the road.
Various exit signs are used on freeways. In urban areas, many exit ramps have more than one lane. Overhead and ground-mounted signs help drivers choose the correct lane to exit or stay on the freeway.
Advance signs use arrows to show which lanes lead off the freeway. Signs are also posted at the exit.
Sometimes one or more lanes may lead off the freeway. The arrows matching the exit lanes are shown on the advance sign in a yellow box with the word 'exit' under them.
Freeway interchanges or exits have numbers that correspond to the distance from the beginning of the freeway. For example, interchange number 204 on Highway 401 is 204 kilometres from Windsor, where the freeway begins. Distances can be calculated by subtracting one interchange number from another.
The term 'VIA' is used to describe the roads that must be followed to reach a destination.

Here are some other common signs:
Slow-moving vehicle sign
The "slow-moving vehicle” sign is an orange triangle with a red boarder. It alerts other drivers that the vehicle ahead will be travelling at 40 km/h or less. When on a road, farm tractors, farm implements/machinery, and vehicles not capable of sustaining speeds over 40 km/h must display the slow moving vehicle sign. Watch for these slow moving vehicles and reduce your speed as necessary.
Emergency Detour Route (EDR) sign
EDR signs are used during the unscheduled closure of a provincial highway when OPP detour all traffic off the highway. The EDR markers are located along alternative routes and provide direction to motorists around the closure and back onto the highway.
Long commercial vehicle (LCV)
This placard indicates a long commercial vehicle, which is a double trailer and can be up to 40 metres in length. It is important to be able to recognize an LCV on the highway, based on rear signage, and anticipate both extended length and limited speed when preparing to pass one on the highway.
Emergency response signs
Some information signs include a numbering system along the bottom of the sign to assist emergency vehicles and drivers
in determining an appropriate route.
Watch for these signs when driving in designated bilingual areas. Read the messages in the language you understand best. Bilingual messages may be together on the same sign or separate, with an English sign immediately followed by a French sign.
