Challenging conditions (continued)
Visibility is reduced at night. Do not overdrive your headlights. Travel at a speed that allows you to respond safely or stop in the distance lit by your headlights.
Glare
Glare from the sun, reflections, and the lights of other vehicles can affect your vision in the daytime or at night. If glare makes it difficult to see the road, reduce your speed. Ensure your vehicle’s windows are properly cleaned inside and outside to improve visibility.
Smoke and fog
Use low beam headlights in smoke and fog, as high beams reflect the light back to you, creating glare. If visibility becomes so poor that it is no longer safe to continue driving, slow down and move your vehicle well off the road to a safe location. Turn on your hazard warning lights. Do not attempt to drive until conditions improve. If a safe place to park is not available, ensure that you and your passengers move to a safe location away from the vehicle in case it is hit.
When driving at night
Road surface conditions that affect traction
Black ice
Black ice is caused by moisture freezing on the road surface. Often a driver cannot see it. However, if the asphalt looks shiny and black instead of grey-white, be cautious, and reduce your speed without braking.
Shaded areas
Shaded areas may still be icy even after the sun has melted the ice on other parts of the road.
Bridges and overpasses
Bridge decks and overpasses tend to form slippery patches more readily than other road surfaces. Use extra caution and try to avoid unnecessary lane or speed changes.
Use your low beam headlights when you are following within 150 metres (one-and-one-half city blocks) of another vehicle .
Use your low beam headlights when you are within 300 metres of oncoming vehicles.
