Which is the safest type of rear-view mirror to use when towing a caravan?

Why that is the answer

Extended-arm wing mirrors are the safest choice because a caravan is usually wider than the towing vehicle. Standard interior and wing mirrors will be blocked by the caravan body, creating large, dangerous blind spots behind and along the sides. Extended mirrors project further out, giving you an unobstructed view past the caravan. DVSA guidance and UK law require you to fit suitable towing mirrors so you can see clearly behind your vehicle.

How this comes up in the real test

Questions from other types of vehicle 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.
