DVSA Theory Test Questions Everyone Gets Wrong
2026-07-27
Why the same handful of topics keep coming up
DVSA leans on a set of rule categories that matter most for safety, not obscure trivia — priority, distance, and the couple of Highway Code updates that older revision material has not caught up with. Below are real practice questions in DVSA style covering the ones learners get wrong most often.
A quick caveat before you read on: we are not DVSA-licensed, and these are DVSA-style practice questions written to match the real exam’s topics and difficulty — not official or leaked papers. The rules behind them are the same rules DVSA tests.
Priority at roundabouts and unmarked junctions
Q: "When approaching a roundabout, you should normally give priority to:" The correct answer is traffic approaching from your right, unless signs or road markings say otherwise. Most learners get this half right — they know right has priority — but forget the exception: local signs, markings or traffic lights can override the default, so check the roundabout in front of you rather than assuming the general rule always applies.
Q: "Who has priority at an unmarked crossroads?" The correct answer is no one — proceed with great care. This is the question most new drivers get wrong, because every instinct says someone must have right of way. Nobody does: slow right down, make eye contact with other drivers where you can, and be ready to stop.
Stopping distances and what makes them up
Q: "What is the typical overall stopping distance at 30 mph in good, dry conditions?" The answer is 23 metres (75 feet) — about six car lengths. At 70 mph it is 96 metres (315 feet), more than four times further, because braking distance grows with the square of your speed while thinking distance only grows in a straight line. Learners often guess a number that scales in a straight line with speed and land on an answer that is far too short.
Q: "What two elements make up the overall stopping distance?" The answer is thinking distance plus braking distance. Thinking distance is how far you travel in the time it takes to react before you even touch the brake; braking distance is what happens once you do. Mixing the two up, or forgetting thinking distance entirely, is a common wrong-answer pattern.
Alcohol limits and the 2022 Highway Code updates
Q: "In England and Wales, what is the legal maximum blood alcohol level for drivers?" The answer is 80 milligrams of alcohol per 100 millilitres of blood — but as the explanation stresses, driving ability is impaired well below that figure, so the only fully safe choice is not to drink at all before driving. Do not round this down to "a couple of drinks is fine": the legal limit and the safe limit are not the same number.
Q: "How much room should you leave when overtaking a cyclist at speeds of up to 30 mph?" The answer is at least 1.5 metres — a genuine clear gap, not just a car door’s width. This rule came into the Highway Code as part of the 2022 update, so anyone revising from an older book or an out-of-date app will answer with the wrong, smaller gap.
Motorway breakdowns
Q: "Your vehicle breaks down on a motorway. What should you do after stopping on the hard shoulder or in an emergency area?" The answer is to exit through the left-hand door and wait behind the safety barrier, away from the carriageway. The instinctive wrong answers — staying belted in the car, or standing behind the vehicle with a warning triangle — are both explicitly wrong on a motorway: never place a warning triangle on a motorway carriageway.
FAQ
Are these official DVSA exam questions?
No — we are not DVSA-licensed. These are DVSA-style practice questions built to match the real exam’s topics, wording style and difficulty, with explanations extended from the same rules DVSA tests.
What is the fastest way to fix a weak category?
Drill that category alone until you are consistently scoring above the 86% pass mark, then retest it inside a full 50-question mock so it holds up under exam pacing.
Why do stopping distance questions trip up so many learners?
Because braking distance does not scale in a straight line with speed — it roughly matches the square of your speed — so an intuitive guess is usually far too low at higher speeds.
Has the Highway Code changed recently?
Yes — the 2022 update introduced the Hierarchy of Road Users and the 1.5 metre cyclist overtaking distance, both of which now appear regularly in the question bank.
