You have stopped in the emergency area at the side of a motorway. Before you rejoin the main carriageway, what must you do?

Why that is the answer

You must use the emergency telephone provided before leaving an emergency area. The control centre operator will tell you when it is safe to rejoin the motorway and can set electronic signals or close the nearside lane to help you merge safely. Moving off on your own, even with hazard lights on, is extremely dangerous because vehicles in the live lane are travelling at high speeds.

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.
