Hazard warning lights

You shouldn’t have to use these lights very often, but it’s important to know when you should and to use them correctly. Your hazard warning lights are basically your orange indicator lights both flashing at the same time, indicating a warning to other drivers. The button to turn on your hazards is on your dashboard in the shape of a red triangle that flashes when they’re on.

These lights are generally used in the event of a breakdown. If you feel your car is losing power, put your hazards on to warn other drivers that you may be about to slow down or stop suddenly. If you break down, make sure they’re on to warn other drivers that you pose a potential hazard. Switch them on even if it’s daylight and on the hard shoulder of a dual carriageway or motorway.

You may also spot drivers using hazard lights to warn other drivers of a potential hazard ahead. If, for example, traffic suddenly starts to slow down on a motorway, drivers might put their hazards on to warn those behind them to slow down. The car behind them will then do the same, and drivers will know to slow down.

However, putting your hazards on doesn’t give you an excuse to park wherever you want, and a traffic warden will still give you a ticket whether you have them on or off. You might also see people using their hazards to thank drivers behind them. It’s best not to do this, as it can send confusing signals to drivers around you.
