If you break down on a motorway, get the car as far left as possible, put on hazard lights, and get out on the side away from traffic — behind the barrier if there is one. Never stand between your car and moving traffic. On a smart motorway with no hard shoulder, if you can't reach an emergency refuge area, stay belted in with hazards on and call 999 immediately. National Highways data shows people are killed or seriously injured on hard shoulders and live lanes every year, almost always because they stayed too close to the carriageway.
At a glance
| Situation | What to do first |
|---|---|
| Standard motorway, hard shoulder available | Pull fully onto the hard shoulder, hazards on, exit passenger side, stand behind the barrier |
| Smart motorway, no hard shoulder | Get to the nearest Emergency Refuge Area (roughly every 1.5 miles) if you can reach it |
| Can't move out of a live lane | Keep seatbelts on, hazards on, call 999 — do not get out |
| A-road or country road | Pull onto verge or lay-by if possible, hazards on, use a warning triangle well back |
| Any breakdown at night or bad weather | Wear a hi-vis vest before leaving the car |
Why motorway breakdowns are more dangerous than they feel
A car sitting still at the side of a road doing 70mph traffic is one of the highest-risk situations an ordinary driver faces. National Highways has repeatedly flagged that most hard-shoulder deaths and serious injuries happen to people who stayed in or near their vehicle rather than getting clear of the carriageway. The danger isn't the breakdown itself — it's what happens in the minutes afterward if you don't put distance between yourself and live traffic.
The first 60 seconds
- Indicate and move left as early and as smoothly as possible.
- Put your hazard lights on the moment you sense trouble, not after you've stopped.
- Steer onto the hard shoulder or verge, as far left as the road allows.
- Turn your wheels away from the carriageway so the car won't roll into traffic.
- Exit through the passenger-side door if it's safer, and get behind a barrier if there is one.
Smart motorways with no hard shoulder
Sections of motorway with no permanent hard shoulder rely on Emergency Refuge Areas (ERAs), spaced roughly every 1.5 miles, and radar-based detection that closes the lane with a red X. If you feel trouble coming on, try to reach an ERA or a slip road rather than stopping in a live lane. If you can't get clear, stay belted in, keep hazards on, and call 999 straight away — control rooms can close the lane remotely once they know you're there.
Waiting for recovery
Once you're safely off the carriageway (or in an ERA), call your breakdown provider or, if you're in a live lane, 999. Wear a hi-vis vest if you have one, especially at night or in poor visibility. Keep any passengers, including pets, out of the car and behind the barrier — not standing beside it. Only use a warning triangle well back from the vehicle, and never on the motorway carriageway itself, where it's illegal and dangerous to place one.
Common mistakes that make breakdowns riskier
- Stopping in a live lane instead of pushing on to the next refuge area or exit if it's safe to do so.
- Standing behind the car to direct traffic — always move to the verge or behind a barrier instead.
- Trying to fix the fault yourself on the hard shoulder rather than waiting for recovery.
- Leaving children or pets inside the car if it's not in a place of safety.
- Not calling for help immediately because you assume you can 'nurse it' to the next services.
