Which vehicles are prohibited from using the right-hand lane of a three-lane motorway?

Why that is the answer

Vehicles towing a trailer are prohibited from using the right-hand lane on a motorway with three or more lanes. The Highway Code sets this rule to keep traffic moving smoothly, as towing vehicles are restricted to a lower speed limit of 60 mph. Other road users, including delivery vans and motorcycles, are allowed to use the right-hand lane for overtaking, provided they follow the relevant speed limits for their vehicle type.

How this comes up in the real test

Questions from motorway rules 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.
