Key takeaways

  • A qualified accompanying driver must sit in the front passenger seat.
  • G1 drivers must maintain zero blood alcohol and cannot drive from midnight to 5 a.m.
  • Most 400-series highways and high-speed expressways are prohibited unless a certified Ontario driving instructor accompanies the learner.

Supervision and passengers

The accompanying driver needs a full licence and at least four years of driving experience, and must meet Ontario's blood-alcohol requirement. That person must be the only other person in the front seat.

  • Every passenger needs a working seatbelt.
  • The accompanying driver must be ready and legally able to supervise.
  • Passenger choices must never interfere with safe control of the vehicle.

Time, alcohol, and road restrictions

G1 drivers may not drive between midnight and 5 a.m. and must maintain zero blood alcohol. Ontario also restricts G1 driving on 400-series highways and listed high-speed expressways, subject to the certified-instructor exception.

  • Plan practice sessions outside the prohibited hours.
  • Choose roads appropriate for the learner's current ability.
  • Confirm that any supervising instructor is certified in Ontario.

Check for changes

Restrictions are legal requirements, not study tips. Verify the current Ontario page before driving, especially after a policy or licence change.
