Before You Open a Car Door: Make Space for Cyclists

Driver checks behind before opening a closed car door

The journey is not over until everyone has got out safely

Parking safely includes checking what is happening beside and behind your vehicle before you open a door. A cyclist or motorcyclist may be approaching, and a door opened into their path can leave very little time to react.

Check all around, then use your mirrors

Highway Code Rule 239 requires you to make sure you do not hit anyone when opening a door. Look around and use your mirrors to check for cyclists and other traffic. Keep the door closed while someone passes, and check again before opening it.

A useful habit: reach with the opposite hand

Where you can, use the hand furthest from the door to open it. For a door on your right, this means using your left hand. The movement helps turn your head towards your shoulder so you can check behind. It supports your observations; it does not replace them.

Think about passengers too

Passengers should check before opening their doors as well. It is safer, especially for children, to leave the car on the side beside the kerb. Even there, check for people using the pavement.

Try this on your next journey

Before anyone gets out, pause with the doors closed. Check mirrors, look all around and confirm the space beside the vehicle is clear. Make that final check part of parking rather than an afterthought.
