A car breakdown is a stressful and potentially dangerous event. Knowing the correct safety procedures can protect you, your passengers, and other road users. This guide provides clear, step-by-step instructions for handling a vehicle breakdown safely on any UK road, from quiet country lanes to busy smart motorways. Following these roadside emergency guidance steps ensures you are prepared for when your car stops working.
Immediate Actions: What to Do First When Your Car Breaks Down
The first thing you should do if your car breaks down is to alert other drivers and move to a safe location if possible. Your immediate priority is to minimize danger to yourself and others.
Find a Safe Place to Stop
If your car develops a problem, try to exit the flow of traffic smoothly.
- Activate Hazard Lights: Turn on your hazard warning lights instantly. This is the universal signal for a problem and warns drivers behind you.
- Pull Over: If possible, pull over to the left side of the road. Aim for the hard shoulder on a motorway, a lay-by, or a verge. Avoid stopping on bends or at the crest of a hill where visibility is poor.
- Slow Down Gradually: Brake gently to avoid sudden movements. Use your engine to help slow the vehicle by changing down through the gears.
Secure Your Vehicle
Once you have stopped, take steps to ensure your vehicle is secure.
- Engage the handbrake firmly.
- Switch off the engine.
- Put your vehicle into ‘Park’ if it is an automatic, or leave it in gear if it is manual.
- Turn your front wheels towards the kerb. This prevents the car from rolling into traffic if the handbrake fails.
- Keep your sidelights on at night or in poor visibility.
Navigating a Breakdown on Motorways and A-Roads
The dangers of breaking down on the motorway are significant due to the high volume and speed of traffic. Understanding the specific procedures for these roads is a critical part of vehicle breakdown safety.
Standard Motorway Breakdown Procedure
If you break down on a motorway with a continuous hard shoulder:
- Move onto the Hard Shoulder: Pull over as far to the left as you can, leaving space between your vehicle and the live traffic lane.
- Exit on the Left: All occupants must exit the vehicle through the left-hand doors, away from the moving traffic.
- Find a Safe Position: Move up the embankment or behind a safety barrier if one is present. Stand well away from your vehicle and the carriageway. Never stand between your car and the flow of traffic.
- Do Not Attempt Repairs: Never try to perform even minor repairs on a motorway hard shoulder. The risk from passing vehicles is too high.
What to Do on a Smart Motorway
Smart motorways use technology to manage traffic flow and sometimes use the hard shoulder as a live lane. This requires different safety precautions.
What if I break down in a smart motorway lane?
If your car breaks down in a live lane on a smart motorway because you cannot reach an Emergency Refuge Area (ERA), your actions are critical.
- Stay in the vehicle. Keep your seatbelt on.
- Activate hazard warning lights immediately.
- Call 999. Inform the police of your location and that you are in a live lane. They will close the lane using the overhead signals.
If you can, try to drive to an ERA. These are spaced regularly and marked with blue signs featuring an orange SOS telephone symbol. Once in an ERA, exit the vehicle on the left, stand behind the barrier, and use the emergency phone to contact the control centre.
Is it safer to stay in your car or get out during a breakdown?
On a motorway or high-speed road, it is safer to get out of your car. You should exit through the left-hand doors and wait for assistance behind a safety barrier or up on the verge, well away from the vehicle. On a quiet, single-carriageway road where your vehicle is not causing an obstruction and you feel vulnerable, it may be safer to stay inside with the doors locked. Assess the specific situation to make the safest choice.
How to Make Your Broken-Down Vehicle Visible
Ensuring other road users can see your stationary vehicle is a key component of car breakdown safety, especially at night or in bad weather.
Using Hazard and Sidelights
Your hazard warning lights are the most important tool for visibility. They should be the first thing you switch on and the last thing you switch off. If you break down at night or when visibility is poor, also leave your sidelights on.
How to Use an Emergency Reflective Triangle
A warning triangle provides an advanced visual alert to oncoming drivers. However, it is crucial to use it correctly and safely.
How far behind a broken down car should a warning triangle be placed?
A warning triangle must be placed at least 45 metres (147 feet) behind your vehicle on the same side of the road. This distance gives other drivers enough time to see the hazard and react safely. When placing the triangle, carry it facing oncoming traffic so you remain visible. Never use a warning triangle on a motorway, as walking on the carriageway is extremely dangerous.
Calling for Help: Getting Roadside Assistance
Once you are in a safe location, the next step is to call for help. Having breakdown cover is essential for any driver in the UK.
Contacting Your Breakdown Service
Use your mobile phone to call your breakdown provider. Be ready to provide them with:
- Your precise location. Use a GPS app or look for driver location signs on motorways.
- Your vehicle’s make, model, and registration number.
- A description of the problem.
- Your membership number.
When Should I Call 999 if My Car Breaks Down?
You should call 999 only if you are in a position of immediate danger. This includes stopping in a live lane of traffic on a motorway or A-road, or if your vehicle is in any location that puts you or other road users at risk. You should also call 999 if someone has been injured. For a standard breakdown in a safe location, you should contact your breakdown service provider directly.
What to Do With No Mobile Signal
Breaking down with no mobile signal can be alarming, but there are procedures in place.
How do you signal for help in a rural area?
If you have no signal in a remote location, stay with your vehicle. It provides shelter and makes you easier to find. If it is safe to do so, you can raise the bonnet of your car, which is a recognised signal of a breakdown.
On UK motorways, orange SOS emergency telephones are located at regular intervals along the hard shoulder. These phones connect you directly to National Highways or the police, who can pinpoint your location and help you contact your breakdown service.
Vehicle Emergency Preparedness: Your Kit and Knowledge
Being prepared can turn a major crisis into a manageable inconvenience. A well-stocked emergency kit and basic breakdown prevention knowledge are invaluable.
The Essential UK Emergency Car Kit
While there are no items you legally must carry in your car in the UK for emergencies, a basic kit is highly recommended for your safety.
An effective emergency car kit should include:
- A high-visibility jacket or roadside safety vest for each occupant.
- A fully charged mobile phone and a portable power bank.
- A warning triangle (for use on non-motorway roads).
- A torch with spare batteries.
- A first-aid kit.
- A bottle of water and non-perishable snacks.
- Sturdy footwear.
Preparing for a Winter Breakdown
Winter adds extra challenges. Your emergency items for a car breakdown in winter UK conditions should be expanded.
- Warmth: Include a blanket, hat, gloves, and a warm coat.
- Supplies: Pack extra food, water, and a hot drink in a flask.
- Equipment: A shovel, de-icer, and an ice scraper can be essential.
If your car breaks down in winter, run the engine for 10 minutes every hour to keep the battery charged and to use the heater for warmth. Ensure the exhaust pipe is clear of snow to prevent a build-up of carbon monoxide fumes.
Portable Car Jump Starter Safety Instructions UK
A flat battery is a common cause of a car not starting. A portable jump starter can help, but you must follow safety instructions.
- Ensure both the vehicle ignition and the jump starter are switched off.
- Connect the red (positive) clamp to the positive (+) terminal of the car battery.
- Connect the black (negative) clamp to a solid, unpainted metal part of the car’s chassis, away from the battery.
- Turn on the jump starter.
- Attempt to start the car.
- Once the car starts, turn off the jump starter before disconnecting the clamps in reverse order (black first, then red).
Specific Safety Scenarios
Different situations require tailored safety considerations to ensure the well-being of all passengers.
Roadside Safety Tips for Women Driving Alone UK
Personal safety is paramount. If you break down while driving alone, consider these additional safety measures.
- If you can stop in a safe, well-lit area, it may be better to remain in your vehicle with the doors locked.
- Call your breakdown provider and a friend or family member to let them know your location.
- Do not accept help from strangers who stop. Wait for the official breakdown service or the police. If someone makes you feel unsafe, call 999.
What to Do If Your Car Breaks Down at Night with Kids
A car breakdown at night with kids requires you to focus on their safety and comfort.
- Reassure them and explain what is happening in a calm manner.
- If you must exit the vehicle on a busy road, ensure you hold onto them firmly and keep them well away from traffic, behind a barrier.
- Keep them warm with blankets and coats from your emergency kit.
- Have snacks, water, and a game or book to keep them occupied while you wait for assistance.
Simple Breakdown Prevention Tips
The best way to stay safe is to avoid a breakdown in the first place. Regular vehicle maintenance significantly reduces your risk of car trouble.
- Servicing: Follow your car’s recommended service schedule.
- Tyres: Check tyre pressures and tread depth regularly.
- Fluids: Regularly check and top up oil, coolant, and windscreen washer fluid.
- Fuel: Do not risk running out of fuel, especially on long journeys.
- Warning Lights: Never ignore a dashboard warning light. Have it investigated by a professional as soon as possible.
