It is recommended that, if stopped (other than in traffic), you do not leave your headlights on and switch to your ‘side’ or ‘parking’ lights instead. You should not leave headlights on when parked.
What to do if you are dazzled by another vehicle’s headlights or by the sun
Slow down and stop if necessary.
Always watch for pedestrians or cyclists on your side of the road.
If the dazzle is from an oncoming vehicle or you are being blinded by the sun then you can avoid this by looking towards the verge (edge of your side of the road) until the effect has passed. If the dazzle is from a vehicle behind you and reflected in your mirror, operate the night-driving mode on the mirror.
Driving carefully behind other vehicles
Section 8 covers the importance of keeping a safe distance behind vehicles in front of you. In particular, don’t drive on the tail lights of the vehicle in front. It gives a false sense of security and may lure you into driving too close or too fast, or both. If you see red vehicle lights in front of you, dip your headlights to avoid dazzling the driver of the vehicle ahead.
