Below is a free Incidents, Accidents & Emergencies mock test for the UK DVSA car theory test: multiple-choice questions in the official four-option format, each with the correct answer, a plain-English explanation and a Highway Code reference. What to do at the scene of an incident, breakdowns, first aid basics and warning devices.
Incidents, Accidents & Emergencies practice questions
Q1. You're first at the scene of a crash where a motorcyclist is injured. When should their helmet be removed?
- Straight away, so they can breathe more easily
- Only if it's essential — for example, to restore breathing
- As soon as the ambulance is called
- Whenever the rider asks, regardless of injuries
Answer: B. Removing a helmet can worsen head and neck injuries. Leave it on unless it's essential to keep the casualty's airway open, and get medical help urgently. Reference: The Highway Code — rule 283 and Annexe 7: First aid on the road
Q2. Your car breaks down on a two-way road. How far behind it should you place a warning triangle?
- At least 45 metres, on the same side of the road
- 5 metres, next to the boot
- At least 150 metres, on the opposite side
- Warning triangles are illegal in the UK
Answer: A. Place the triangle at least 45 metres (147 feet) behind the vehicle on the same side of the road to give approaching drivers time to react. Never use one on a motorway. Reference: The Highway Code — rule 274
Q3. You're involved in a collision that causes damage or injury and you don't exchange details at the scene. What must you do?
- Nothing further, provided you stopped
- Report it to your insurer within 30 days only
- Report it to the police as soon as reasonably practicable, and within 24 hours
- Leave a note on the other vehicle
Answer: C. You must always stop at a collision involving injury or damage. If you don't give your details to anyone with reasonable grounds to ask, you must report to the police as soon as practicable — at most within 24 hours. Reference: The Highway Code — rules 286–287
Q4. When may you use your hazard warning lights while moving?
- When you're being towed
- On a motorway or unrestricted dual carriageway, briefly, to warn drivers behind of a hazard or obstruction ahead
- Whenever you're driving slowly
- When parking on double yellow lines
Answer: B. Hazard lights are for when you're stationary causing a temporary obstruction — the one moving exception is briefly warning traffic behind of a hazard ahead on a motorway or unrestricted dual carriageway. Reference: The Highway Code — rule 116
Q5. Smoke starts coming from under your bonnet as you drive. What should you do?
- Drive quickly to the nearest garage
- Open the bonnet fully to cool the engine
- Pull over safely, get everyone out and away, and call the fire service — don't fully open the bonnet
- Pour water over the engine immediately
Answer: C. Opening the bonnet feeds a fire with air. Stop somewhere safe, get everyone well clear, and call 999. Only tackle a very small, accessible fire if you can do so without risk. Reference: The Highway Code — rule 280 and Annexe 7
Q6. In the DR ABC first-aid routine, what does the B stand for?
- Bleeding
- Breathing — check for normal breathing for up to 10 seconds
- Burns
- Bones
Answer: B. Danger, Response, Airway, Breathing, Circulation/Compressions. After opening the airway, check for normal breathing; if there is none, start chest compressions and send for help. Reference: The Highway Code — Annexe 7: First aid on the road
Q7. A casualty has a wound that is bleeding heavily, with nothing embedded in it. What should you do?
- Apply firm pressure over the wound with a clean pad and raise the limb if possible
- Wash the wound with water and leave it uncovered
- Apply a tourniquet immediately
- Give them a hot drink
Answer: A. Firm, direct pressure with the cleanest material available slows serious bleeding, and raising a limb (if it isn't fractured) helps further. Keep pressure on until help arrives. Reference: The Highway Code — Annexe 7: First aid on the road
Q8. Something falls from your vehicle on a motorway. What should you do?
- Stop on the carriageway and pick it up quickly
- Reverse along the hard shoulder to retrieve it
- Stop at the next emergency telephone and report it — never try to retrieve it yourself
- Carry on and report it when you get home
Answer: C. Never stop on the carriageway or walk on a live motorway for a dropped load. Use the next emergency phone (or 999 in an emergency area) so the operator can arrange safe removal. Reference: The Highway Code — rules 279–280
