What to Do If Your Car Breaks Down – Driving Theory Learner App Guide

Breaking down can happen to any driver - whether it's a flat tyre, engine trouble, or a warning light you didn't expect. Knowing what to do if your vehicle breaks down is essential for your safety and is an important topic for the UK driving theory test.
This guide explains what to do step by step, how to stay safe, and how to prepare in advance.
⚠️ If Your Vehicle Breaks Down
1. Pull Over Safely as Soon as Possible
At the first sign of trouble, slow down and pull over as soon as it's safe to do so. Avoid harsh braking or sudden steering.
- Use a lay-by or parking area if available
- If not, stop on the left-hand side of the road
- On a motorway, aim for the hard shoulder (if available)
Once stopped:
- Turn your wheels away from the road
- Apply the handbrake
- Switch off the engine
Try to stop somewhere visible, away from bends, junctions, or hills so other drivers can see you clearly.
2. Warn Other Road Users
Making your vehicle visible is crucial to prevent collisions.
You should:
- Switch on your hazard warning lights immediately
If it's safe to do so, you can also:
- Wear high-visibility or reflective clothing
- Raise your bonnet to signal a breakdown
- Place a warning triangle on the road at least 45 metres (147 feet) behind your vehicle
(Do not use warning triangles on motorways)
⚠️ Never place warning devices if it puts you in danger, and do not use flares if there is a fuel leak.
3. Get Yourself to a Safe Place
Your safety comes first.
- If you're on a motorway, exit the vehicle via the left-hand door
- Move behind a barrier, up a bank, or well away from traffic
- Keep passengers together and away from the road
If you're on a quiet road and it's safer to stay inside:
- Remain in the car with your seatbelt fastened
- Keep hazard lights on
4. Call for Help
Use your phone to contact:
- Breakdown or roadside assistance
- Emergency services (999) if you're in danger
- Motorway emergency phone if available (these give your exact location)
Be ready to share:
- The road name or motorway number
- Direction of travel
- Nearby landmarks or junction numbers
Stay with your vehicle (or in a safe place nearby) until help arrives.
