DVSA theory test explanation

Drivers and riders may switch on their hazard warning lights to warn following traffic of an obstruction or danger ahead. This only applies on motorways and dual carriageways that are subject to the national speed limit. The hazard warning lights should be turned off again when it's clear the warning has been seen.
