You are driving on a three-lane motorway and wish to overtake a slow-moving lorry in the middle lane showing this sign. How should you do this?

Why that is the answer

Motorway maintenance vehicles often display signs directing traffic which side to pass. Although you would usually overtake on the right, the Highway Code requires you to obey these signs. If a slow-moving lorry displays a sign or arrow directing you to pass on the left, you must overtake on the left with care. Passing on the right as normal is dangerous, as that lane could be closed or blocked further ahead.

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.
