By law, while driving a vehicle, you are required to switch on headlights a half hour before sunset until a half hour after sunrise and when visibility is reduced to 60 metres.

Other recommended practices include:

• sharply reducing your normal driving speed
• turning your headlights on low beam to reduce the glaring reflection from dense fog or snow (Fog lamps are even better.)
• reducing your speed further on seeing headlights or taillights (The headlights may be on a vehicle being driven down the centre of the road, and the taillights may be a vehicle stopped on the road or just barely moving.)
• if driving at a greatly reduced speed, turning your hazard/emergency flashing lights on (This will make you more visible and warn other drivers that you are travelling at a reduced rate of speed.)
• being prepared for emergency stops (If the visibility becomes so poor that you can barely see, cautiously pull off the pavement and stop. Wait until visibility improves.)
