The answer options
- High vehiclesCorrect
- Wide vehicles
- Long vehicles
- Heavy vehicles
Why that is the answer
This sign warns drivers of a height restriction and applies specifically to high vehicles, such as lorries, buses, or vehicles carrying tall loads. Drivers must know their vehicle’s exact height to avoid hitting low bridges or overhead hazards. It doesn't apply to wide, long, or heavy vehicles, which have separate signs showing width, length, or weight limits. The Highway Code stresses the importance of obeying height signs to prevent serious collisions.
How this comes up in the real test
Questions from road and traffic signs 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.
