I. Driving at night and in bad weather
 
Glare
 

Glare is dazzling light that makes it hard for you to see and be aware of what others around you are doing.

It can be a problem on both sunny and overcast days, depending on the angle of the sun’s rays and your surroundings. Glare can also be a problem at night when you face bright headlights or see them reflected in your mirrors.

When meeting oncoming vehicles with bright headlights at night, look up and beyond and slightly to the right of the oncoming lights. In daytime glare, use your sun visor or use a pair of good-quality sunglasses. When you enter a tunnel on a bright day, slow down to let your eyes adjust to the reduced light. Remove your sunglasses and turn on your headlights when driving through a tunnel.

Cut down glare at night by following the rules of the road for vehicle lights. Use your low-beam head­lights within 150 metres (500 ft.) of an oncoming vehicle or when following a vehicle within 60 metres (200 ft.). On country roads, switch to low beams when you come to a curve or hilltop so you can see oncoming headlights and won’t blind oncoming drivers. If you can’t see any headlights, switch back to high beams.
