Rules of the Road
Speed and space
Unless posted otherwise, Ontario's default limits are 50 km/h in cities, towns and villages, 80 km/h on highways outside built-up areas, and 100 km/h on 400-series freeways. Always obey the posted sign, including reduced school-zone and construction limits. Keep at least a two-second following distance in good conditions and double it in rain, snow, darkness or when following a motorcycle or heavy vehicle. The two-second rule is measured by counting from the moment the vehicle ahead passes a fixed object.
Right of way and markings
At an uncontrolled intersection, the vehicle on the right has the right of way; if you arrive at the same time, yield to the right. A vehicle turning left must yield to oncoming traffic and to pedestrians. Broken yellow centre lines permit passing when safe; solid yellow lines forbid it. Never pass at a railway crossing, on a hill, at a curve, or at an intersection.
Special vehicles and crossings
When a school bus displays flashing red lights, traffic in both directions must stop on an undivided road; where a median divides the road, only traffic approaching from behind the bus must stop. When an emergency vehicle approaches with lights and siren, pull to the right and stop. At a pedestrian crossover, stop and wait until pedestrians have completely cleared the roadway.
Worked example
You reach a four-way stop at the same moment as a car on your right, and a pedestrian is waiting at the corner. The car on your right goes first; you follow once it clears, and you still yield to the pedestrian if your path crosses theirs.
Rule of thumb
When in doubt about right of way, yield - a wrong guess costs seconds, not a collision.
