The answer options
- When passing a left turn
- When driving at the maximum speed limit
- When driving at the minimum speed
- When turning right or overtakingCorrect
Why that is the answer
You should always stay in the left-hand lane of a dual carriageway unless you are overtaking slower traffic or preparing to turn right. The Highway Code outlines that the right-hand lane is for overtaking or turning right only. Once finished, you must return to the left lane. Driving at the maximum speed limit does not justify staying in the right-hand lane, as lane hogging disrupts traffic flow and creates an unnecessary hazard.
How this comes up in the real test
Questions from rules of the road 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.
