Speed management rules are vital topics tested on the Ontario G1 written exam. Driving at an appropriate speed ensures you have sufficient time and distance to react to unexpected road hazards. On the G1 test, applicants are evaluated on default unposted speed limits, school zone regulations, and heightened penalties in designated safety zones.

Here is a breakdown of Ontario speed rules, followed by 8 original practice questions.

1. Default (Unposted) Speed Limits

Under the Ontario Highway Traffic Act, if no speed limit signs are posted on a road, statutory default limits automatically apply:

  • Within a city, town, village, or built-up area: Default limit is 50 km/h.

  • Outside built-up areas (rural roads and highways): Default limit is 80 km/h.

2. School Zones and School Crossings

School zones are designated areas near educational institutions where speed limits are reduced—typically to 30 km/h or 40 km/h—during school hours. Speed signs in school zones may feature flashing yellow lights or specific time-of-day indicators. Drivers must exercise extreme caution and watch for children crossing.

3. Community Safety Zones

Community safety zones are sections of roadway designated by municipal bylaws where public safety is a special concern (such as near daycare centers, senior residences, or parks). While the posted speed limit remains the governing speed, monetary fines for speeding infractions committed within Community Safety Zones are doubled.
