Prepare for the UK Driver CPC exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: What is the minimum legal tyre tread depth for commercial vehicle tyres in the UK?
Answer: B. 1.6 mm
Explanation:
The answer is 1.6 mm. That is the legal minimum, and it applies across the central three-quarters of the tread width, not only at one spot on the tyre.
1.0 mm is wrong because it is below the legal minimum. 2.0 mm and 2.5 mm are wrong because they are higher than the legal limit. They might be sensible points to replace a tyre, but they are not the law.
The rule to remember: the legal minimum is a floor, not a target. Check tread across the central part of the tyre as part of your daily walkaround, and replace tyres before they reach the limit if wear is uneven or close.
Question: What is the correct ratio of chest compressions to rescue breaths in adult CPR?
Answer: B. 30 compressions to 2 breaths
Explanation:
The answer is 30 compressions to 2 breaths. This is the ratio for adult CPR, and the compressions are delivered at 100-120 per minute, pressing down 5-6 cm on the centre of the chest.
15 to 1 is wrong because it does not match the adult ratio. 5 to 1 gives far too few compressions between breaths. 10 to 3 has the balance the wrong way round, with too many breaths and too few compressions.
The rule to remember: blood only moves around the body when the chest is pressed, so compressions are the priority. If you cannot or will not give breaths, continuous compressions alone can still help.
Question: How should a professional driver deal with road rage from other road users?
Answer: B. Remain calm, avoid eye contact, do not react, and report the incident if necessary
Explanation:
The answer is to remain calm, avoid eye contact, not react, and report the incident if necessary. This keeps the situation from escalating and keeps you in control of your vehicle.
Retaliating to teach them a lesson is wrong because it feeds the conflict and puts everyone at risk. Speeding up to get away is wrong because you take on danger to escape it. Blocking their path is wrong because it is deliberate obstruction and can provoke a worse reaction.
The rule to remember: a professional driver never takes part in aggression. Stay calm, stop safely if you need to, and report it.
