Do You Know The Car Light Rules?

The nights are getting colder and dark, so there is no time like the present to check your lights are working properly.

Many people think that you only need your lights at night-time. However, we have found this to be incorrect. Lights on your vehicle such as: Brake lights, Headlights, Fog lights and Sidelights should all be used when necessary during the day. Please see specific actions below: -

Brake lights should come on when you use the foot brake.
Headlights should be used when visibility is extremely reduced. However, it is vital to turn these off when visibility improves.
Fog lights should be used also when visibility is extremely reduced. However, exactly like headlights, these need to be turned off as soon as visibility improves.
Sidelightsshould be lit during the day, even if you think it is light enough to manage without them.

Like that of day-time lights, night-time lights are just as important. It is important that you illuminate your way on the road with sufficient lighting. This will ensure that you can see where you are going and that you can be seen, without dazzling other road users.

Did you know that you must always use your headlights at night but you must ensure that they are dipped in built-up areas or when you are behind or approaching other road users, including pedestrians, cyclists and horse riders. This will avoid dazzling other road users.

If you are on the receiving end of dazzling headlights, meanwhile, you should slow down, or if necessary stop, and only continue once you can see the road ahead properly.


Follow these rules and you'll find you're well lit on the roads. It is also important to make sure that you keep your windows clean on the inside and out, especially at this time of year to help minimise sun glare and keep clear focus on the road.
