Your vehicle has broken down on the motorway and you need to call the for help. It is better to use an emergency telephone rather than a mobile phone. Why is this?

Why that is the answer

Emergency telephones connect directly to the police or motorway control centres, automatically pinpointing your exact location. This ensures emergency services know precisely where you are without delay. Although mobile phones work on motorways, describing your exact position can be difficult, especially when stressed. Using the emergency roadside phone removes any guesswork, helping recovery teams and emergency services reach you as quickly as possible.

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.
