The answer options
- On a large goods vehicleCorrect
- On a motorway sign
- On a diversion sign
- On a railway bridge
Why that is the answer
Red and yellow reflective hazard markers are fitted to the rear of large goods vehicles to make them clearly visible, particularly in the dark or in poor weather. These bright markings warn other road users of the vehicle's extra size and length, giving you time to adjust your speed and distance safely. Railway bridges use black and yellow markings instead to highlight low height restrictions, not the red and yellow markers found on heavy vehicles.
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.
