Exit Sign
Exit signs on Ontario highways show the exit number, the name of the road or town at that exit, and the distance or immediate turn required. Ontario numbers exits based on the kilometre post where the exit is located.
Last updated: April 4, 2026
Ontario uses distance-based exit numbering. Exit numbers correspond to the kilometre post along the highway where the exit ramp begins. For example, Exit 55 is located at kilometre 55 of that highway. This system allows drivers to estimate how far apart exits are by subtracting numbers. Exit signs appear in advance and at the exit ramp itself.

What does the Exit Sign mean?
Ontario uses distance-based exit numbering. Exit numbers correspond to the kilometre post along the highway where the exit ramp begins. For example, Exit 55 is located at kilometre 55 of that highway. This system allows drivers to estimate how far apart exits are by subtracting numbers. Exit signs appear in advance and at the exit ramp itself.
What to do when you see it
Note the exit number you need before starting your trip. Count down to the correct exit by watching the exit numbers increase along the route. When your exit approaches, signal early and move to the right lane. Exit signs are posted 1.5 kilometres and 500 metres before the exit on most Ontario highways.
Where you'll see it in Ontario
Exit signs are on all 400-series highways and most provincial highways in Ontario. Some older highways and municipal expressways may use sequential numbering rather than distance-based numbering.
G1 test relevance
G1 test questions on highway driving include how to plan an exit and how far in advance to signal and change lanes. The standard taught is to signal and begin merging toward the exit at least 400 metres before the ramp begins.
Common mistakes drivers make
Leaving an exit too late and cutting across the solid painted line at the ramp entrance is a common error. Once the solid white line begins, you must not cross it. Plan your exit several kilometres in advance.
