Use of vehiclesQuestion #15499Multiple correct
In which cases must the hazard warning lights be switched on?
Explanation
The rules list specific situations where the hazard warning lights must be switched on. They include a forced stop in a no-stopping place, a road accident, being stopped by an officer, driving with a fault, towing, being dazzled, and warning of danger. Saying thank you is not one of their official purposes.
KET reference: KET 91: The hazard warning lights must be on: after a forced stop; in a road accident; when the vehicle is being towed; when the driver is dazzled.
