You can’t see as much in the dark, which makes it harder to drive and increases crash risk. Headlight and tail lights serve two purposes - they help you see at night and in poor light conditions, and help other people see you, even during the day.
Slow down when driving at night to give you more time to identify and react to potential hazards.A car with only one functioning light can be mistaken for a motorcycle, or missed entirely in the dark
You must have your headlights, rear lights and number plate light on:
If your vehicle is fitted with clearance or side marker lights, the same rules apply.
You can use high beams on any road to see further ahead, but they may also dazzle oncoming drivers. To avoid dazzling other drivers, you must change to low beam when:
To alert another driver that you are about to overtake, you can briefly flash your high beams.
If dazzled - slow down, look to the left side of the road and drive to the left of your lane or pull over until recovered.
Only use fog lights in conditions that limit your vision (e.g. fog, rain, dust, smoke). You’re required to switch off the fog lights (front and rear) once conditions improve.
If driving in fog and your vehicle isn’t equipped with fog lights, you can use low-beam headlights during the day.
Hazard lights can only be used in these specific situations:
Always make sure that other road users can see your vehicle when parked - leave parking or even hazard lights on if needed (e.g. if you need to stop by the side of the road in the dark).
