The answer options
- When your direction indicators don't work
- When you are double-parked
- When your vehicle is broken down and causing an obstructionCorrect
- To warn oncoming traffic you wish to stop
Why that is the answer
Hazard warning lights should be used when your vehicle has broken down and is causing an obstruction, or on high-speed roads to warn traffic behind of sudden slowdowns ahead. You must never use them while driving in normal traffic, nor as an excuse for unsafe or illegal parking, such as double-parking. Turning on hazard lights does not give you permission to stop where it is unsafe or prohibited.
How this comes up in the real test
Questions from hazard awareness appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
