In a different light

This week’s tips from the IAM’s director of standards, Mark Lewis, are about driving with the correct lights on under different circumstances on the road. Read our latest tips to find out more.

  1. Lots of cars now have dashboard warning lights to let you know of a bulb failure, however, you should still check your lights manually on a regular basis. If any bulbs need replacing, change them beforehand to reduce the risk of any road incidents taking place.
  2. Use your full beam lights only when you’re driving on an unlit road and where there is no vehicle in sight ahead of you. However, remember to switch back to your dipped headlights to avoid dazzling other road users, including pedestrians and cyclists.
  3. Dipped headlights can be used during any time of the day and should be switched on in poor weather conditions. Don’t rely on daytime running lights as the rear lights will not switch on with them – they are not sufficient in reduced visibility conditions. 4
  4. If you cannot see beyond 100 metres switch on your fog lights. It’s illegal to drive with fog lights on in clear visibility so don’t forget to turn them off.
  5. Hazard warning lights may be used when your vehicle is stationary to warn that it is temporarily obstructing traffic. However, don’t use them while you’re driving or being towed unless you are on a motorway or unrestricted dual carriageway and you need to warn drivers behind you of a hazard.
It is so important to make sure you can see and be seen at all times, so keep all lights working correctly and use them when you need to
