Car sidelights: what are the driving rules and regs?

Monday, November 22nd, 2010

When we hear the term ‘sidelights’, most drivers will automatically think of the small / dim lights on the front of the vehicle.

However, this term also includes the rear number plate light.

In some cars, these lights come on automatically when the engine is switched on.

It is true to say that sidelights are of limited use when compared with headlights, particularly in winter weather conditions.  However, there are certain times where their use is vitally important.  We’ll cover this in our fifth winter driving blog post:

Sunset and Sunrise

Sidelights must be switched on between sunset and sunrise even in brightly lit areas as they will help other road users to see your vehicle.

If you have a dark coloured car, you may consider switching on these lights earlier.

Parking

Sidelights must be switched on when your car is parked on a road (or a lay-by on a road) where the speed limit is greater than 30mph.  This will make it easier for other road users, particularly motor vehicles, to see you.

They must also be switched on if your vehicle, for unavoidable reasons, is parked on any road in fog.

In summary; although sidelights do not provide enough light for you to effectively plan your drive at night, they can, when used correctly, provide valuable information to other road users, thus reducing the risk of you and your vehicle being involved in a road traffic incident.

Next week we’ll look at driving in snow and ice to prepare you for the impending colder weather!

 

Car headlights – when to use and when not to use

Do you know when you should be using your car headlights and the rules for usage and best practice?

Read our guide on headlights, which forms the third part of our winter driving series.

Headlights help you to see and be seen by others and must be used when visibility is seriously reduced.

They need to be checked regularly and kept clean or they will be less effective.

Key tips for headlight usage:

•    At night or during the day with poor visibility
Use the main beam on unlit roads as this enables you to see the greatest distance, unless you are following another vehicle or meeting oncoming traffic.  In these cases, dip your lights to avoid dazzling other road users.  Keep headlights dipped in built up areas.

•    In fog
Don’t use the main beam headlights in fog as the fog will reflect the light back and could dazzle you.  Use dipped headlights instead, along with fog lights.  These will be seen from a greater distance than sidelights.

•    In heavy rain or snow
Poor weather conditions can drastically reduce your visibility, so use headlights to make your presence clear to other roads users.

When driving, avoid looking directly at oncoming headlights as this can cause disorientation; if an oncoming vehicle leaves its main beam on, don’t retaliate by leaving yours on.

Headlights on a left-hand bend need to be dipped earlier as they will cut across the vision of anyone coming towards you.

Remember that extra weight at the rear of the vehicle could raise the angle of the headlight beam and dazzle other road users.  In many modern vehicles you can adjust this.

Switch off headlights when parked or they can confuse and dazzle other road users.
