95. Hazard lights

Hazard lights, also called hazard warning lights, make all of a vehicle's direction indicators flash simultaneously. They are used to warn other road users that the vehicle or traffic situation presents an unusual or immediate danger.

Hazard lights may be appropriate after a breakdown, collision or when warning following traffic of a sudden hazard. They should not normally be used as a substitute for proper parking, signalling or vehicle lighting.

What are hazard lights used for?

Hazard lights warn other road users of an unusual or potentially dangerous situation involving the vehicle or traffic ahead. Common examples include breakdowns, collisions and sudden obstructions.

Do hazard lights give a driver permission to park anywhere?

No. Switching on hazard lights does not normally make prohibited stopping or parking legal. The driver must still comply with the applicable stopping and parking rules.

Can hazard lights be used to warn drivers behind of sudden congestion?

In many countries they may be used briefly to warn following traffic of an immediate danger such as a sudden queue. The exact rules governing their use vary between countries.
