What to Do When Your Car Breaks Down — Complete UK Guide

A car breakdown is stressful at the best of times. At the worst of times — in the dark, on a busy motorway, in the rain — it can feel genuinely frightening. But knowing exactly what to do before it happens makes all the difference. This complete guide covers every scenario: motorway, A-road, town centre, and car park.

Immediate Steps — Whatever the Location

Whatever the situation — motorway, A-road or town centre — the very first things to do are the same:

Breaking Down on a Motorway

Motorway breakdowns carry the highest risk due to traffic volume and speed. Follow these steps exactly:

Pull onto the hard shoulder (or ERA)

Drive as far to the left as possible. On Smart Motorway sections with no hard shoulder, look for orange Emergency Refuge Areas (ERAs) — signed every 500 metres.

Exit the vehicle — passenger side only

Never exit from the driver's door on a motorway. Open the passenger door and exit left, away from the carriageway. Get all passengers and pets out immediately.

Stand behind the crash barrier

Move everyone up the bank or behind the barrier. Never stand between the barrier and your car. If your car is hit by a passing vehicle, you want to be completely clear.

Call for recovery

Use your mobile phone or the free orange SOS telephone boxes (located every mile). Give your location — use the marker posts beside the hard shoulder to identify your position (these show your exact motorway location).

Breaking Down on an A-Road or Dual Carriageway

A-roads present a different challenge — there's no hard shoulder, but traffic speeds are still high. The key steps are:

• Turn into a lay-by, side road or entrance if one is close enough — even if it means losing momentum
• If you cannot reach a lay-by, try to stop on the nearside verge as far from the carriageway as possible
• Switch on hazard lights and place warning triangles approximately 45 metres behind your vehicle (at least this distance on A-roads, unlike motorways)
• Stay away from fast-moving traffic — stand in front of your car or on a verge, away from the road
• Be especially careful at night — wear a hi-vis if you have one

Breaking Down in a Town Centre

Town centre breakdowns are the least dangerous but can cause traffic congestion. Here's what to do:

If you can move the car

If the engine has stalled or cut out but the car can be restarted or pushed, move it to a nearby side street, car park or bus stop recess — anywhere out of the flow of traffic. Switch on hazard lights and contact recovery.

If you cannot move the car

Stay in the car with hazard lights on. Place warning triangles if you have them and it's safe to do so. Call recovery and, if the car is blocking traffic, consider calling 101 (non-emergency police) to inform them and request traffic management if needed.

Breaking Down in a Car Park

Car park breakdowns are relatively low-risk but have their own complications — particularly multi-storey car parks with low clearance.

• Try to coast to a parking bay rather than blocking traffic lanes
• Switch hazard lights on
• When calling recovery, specify whether it's ground level or multi-storey — flatbed trucks cannot enter multi-storey car parks with low-clearance decks
• Many breakdowns in car parks are battery-related — a jump start can often get you moving without recovery

Common Causes of Breakdowns — and What to Check

While waiting for recovery, you can often identify the cause (though rarely fix it safely on the roadside). The most common causes are:

Flat Battery

The most common breakdown cause in the UK. Signs: car won't start, clicking noise when turning the key, warning lights appearing without engine starting. A jump start from recovery may get you going — or the battery may need replacing.

Flat or Burst Tyre

Signs: sudden change in steering, pulling to one side, thumping noise from a wheel. If it's a slow puncture you may notice it deflating while driving. Only change a tyre yourself if you are completely off the road and it is safe to do so.

Overheating Engine

Signs: temperature gauge in the red zone, steam from the bonnet, burning smell. Stop the car immediately. Do not open the bonnet or the coolant cap — boiling coolant under pressure can cause serious burns. Call recovery and let the engine cool for at least 30 minutes before any attempt to investigate.

Alternator Failure

Signs: battery warning light comes on while driving, electrical systems starting to fail (lights dimming, radio cutting out). The alternator charges your battery while the engine runs. If it fails, you'll have limited time before the battery drains completely.

Run Out of Fuel

Signs: fuel warning light, then the engine cutting out. Keep in mind that running out of diesel can damage the fuel injection system — it's not just an inconvenience. We carry jerry cans and can deliver fuel to your location as part of our roadside assistance service.

What Information to Have Ready When You Call Recovery

When you call us, having this information ready speeds up your recovery:

• Exact location: Road name, junction number, nearest landmark or postcode
• Vehicle details: Make, model, colour and registration
• What happened: Any warning lights, sounds, or symptoms
• Can the car roll? Is it in neutral, are the wheels intact?
• Destination: Where do you need the car taken?
• Your phone number so we can call if we need to find you

Should You Try to Fix the Problem Yourself?

In some situations, yes — but only if it is completely safe to do so:

• Flat tyre in a safe location: Changing a wheel is fine if you're in a car park or well off the road with hazard lights on
• Jump start: If another driver stops to help and your battery is flat, a jump start is safe in most locations
• Never attempt repairs on a motorway hard shoulder — even if you think you can fix it quickly. The risk is too high.
