Dazzled by Headlights at Night: Slow Down and Keep Control

An approaching vehicle’s headlights can briefly make the road difficult to read. The key response is to reduce your speed and, if necessary, stop. Do not continue simply because you know the road or want to keep pace with traffic.

React calmly

Highway Code Rule 115 says to slow down and, if necessary, stop when dazzled by oncoming headlights. Avoid responding with full beam: that can dazzle the other driver and adds another problem. Keep your own lights from causing discomfort to people coming towards you or travelling ahead.

Match speed to the view

Rule 126 says you should drive at a speed that lets you stop well within the distance you can see clearly. At night, darkness and glare can reduce that usable view. The posted limit does not mean that travelling at that speed is sensible in every situation.

Imagine that you are approaching a bend on an unlit road. If glare prevents you from seeing the bend clearly, the useful question is whether you can stop safely within the visible stretch. Reduce speed early enough to retain control rather than waiting for a hazard to appear.

Remember the difference

Dipped headlights reduce the risk of dazzling others. They do not guarantee that someone else will use their lights correctly. You still need to respond to the visibility you actually have.
