How to Drive at Night in Ontario

At night, your field of vision shrinks dramatically. Even with headlights, you can typically see only 50-100 metres ahead clearly, compared to much greater distances in daylight. Hazards like pedestrians in dark clothing, animals, and road debris are harder to detect. Reaction time requirements increase because you have less time to respond once you spot something.

Reduce your speed at night, even if road conditions appear dry. Your headlights have a limited range, and driving at high speeds means you may not have enough distance to stop for something you see. Increase your following distance beyond the standard 2-second rule, particularly on unlit roads. More distance gives you more time to react to brake lights, stopped vehicles, or hazards the car ahead reveals.

High beams significantly extend your visibility on unlit roads. Use them whenever there is no oncoming traffic and no vehicle ahead of you that you could blind. You must switch to low beams when an oncoming vehicle is within 150 metres, or when you are following another vehicle closely. Forgetting to switch is both dangerous and can result in a fine. High beams are not appropriate on well-lit city streets where street lighting already provides adequate visibility.

Fatigue is one of the biggest risks of night driving. Your body's natural circadian rhythm dips between 2 and 5 a.m., making it harder to stay alert even if you do not feel tired. Signs of drowsy driving include difficulty focusing, frequent blinking, missing exits or turns, and drifting in your lane. If you notice any of these, pull over safely, take a break, or stop for the night.

If you hold a G2 licence, you have specific nighttime restrictions. Between midnight and 5 a.m., the number of passengers you can carry is limited based on your licence stage. Understand your specific restrictions before driving late at night to avoid a violation.
