United Kingdom motorway breakdown: Get left, get safe and get help. If you can, leave the motorway at the next exit or reach a service area. If stopped in a live lane or you cannot get to safety, keep your seat belt and hazards on and call 999 for police immediately.
Do these 12 things now — motorway breakdown checklist
- Try to leave the motorway safely. If the car can still be driven safely, use the next exit or service area instead of stopping on a fast road.
- Go left if you cannot leave. Signal and reach an emergency area or the hard shoulder if available; get as far left as conditions safely allow.
- Put hazard warning lights on. Use sidelights at night or in poor visibility.
- Stop with room to exit away from traffic. Turn wheels left where advised and stop safely without obstructing other drivers more than necessary.
- Get out on the side away from moving traffic if safe. Make sure passengers, including children, use the safe side when possible.
- Move behind a safety barrier. Stand well away from the vehicle and carriageway; watch for hidden drops, debris and poor ground.
- Never put a warning triangle on the motorway. Do not attempt a roadside wheel change or repair beside fast-moving traffic.
- Use an emergency SOS telephone when you can reach it safely. In an emergency area, use its phone before rejoining the motorway.
- Call your breakdown provider. If in England, National Highways may be contacted on 0300 123 5000 for road assistance and coordination.
- Call 999 for police if trapped in a live lane, unable to exit safely or in danger. Keep hazards on and seat belts fastened while awaiting instructions.
- Tell responders your exact location. Use the motorway number, carriageway direction, junctions, driver-location signs or the vehicle’s SOS and mapping features.
- Do not return to the vehicle for belongings. Follow police, traffic officer and recovery personnel’s directions before moving or rejoining the road.
If you are currently stranded in moving traffic, call 999 immediately and ask for police. Follow the Highway Code and the call-taker before reading the longer explanations.
A car stopping on a UK motorway is not an ordinary parking problem. Fast traffic, a lack of stopping space, limited visibility and people leaving the vehicle can quickly turn a mechanical fault into a collision hazard. The Highway Code puts personal safety before repairs, documentation and recovery arrangements.
This guide explains motorway breakdown safety across Great Britain using the Highway Code. The National Highways operational phone number and road-service examples apply to England; Scotland and Wales have their own road-operating authorities, while the 999 emergency number applies across the United Kingdom.

The most important decision: where can the car stop?
The safest breakdown stop is usually a place designed for parking, such as a service area, if the vehicle can still be driven safely. If that is unavailable, a designated emergency area, hard shoulder or suitable verge may offer a place of relative safety. The hard shoulder is not equivalent to a secure car park: traffic is passing at high speed.
The Highway Code says a driver developing trouble should leave at the next exit or pull into a service area if possible. Do not try to continue driving a dangerously defective vehicle simply to reach a particular landmark. If the car is losing power, use your indicators and hazard lights as appropriate and move left as safety permits.
What an emergency area looks like
On some motorways there are marked emergency areas with orange surfacing and SOS telephone signs. These are spaces intended for emergencies, not breaks, phone calls or routine rest stops. If you pull into one, use the emergency telephone to speak with the road operator; before rejoining, the Highway Code requires following the operator’s advice because a lane may have to be controlled.
If there is a hard shoulder, try to stop beyond an emergency telephone when possible and safely leave room for occupants to get out away from traffic. Do not reverse along the hard shoulder to find a more convenient phone or junction.
How to leave the vehicle and wait safely
Switch on hazard lights. When there is a safe route from the stopped car to land away from moving traffic, occupants should exit from the side furthest from traffic. On a typical UK motorway, that is the left-hand side. Where a safety barrier exists and it is safe to reach, move behind it while remaining alert for uneven ground, sudden drops or roadside hazards.
The car is not a shelter once you are already safely outside. A second collision can strike a stationary vehicle without warning, and being next to it can be dangerous. Do not stand between the vehicle and approaching traffic, in front of it or at the back checking the boot.
Keep children under direct adult supervision and ensure nobody moves toward the carriageway. Where a pet cannot be controlled safely outside, follow the Highway Code: animals should generally be kept in the vehicle or controlled on the verge in an emergency. Do not release a dog that might run into traffic.
Wear high-visibility clothing if it is readily available without wasting time or exposing yourself to danger. Otherwise concentrate on getting clear, contacting help and remaining visible from a safe position.
If the car stops in a live traffic lane
This is a high-risk situation. If you cannot move the car left or cannot safely get out and reach a place well away from traffic, stay inside, keep your seat belt fastened and hazard lights flashing, and call 999 immediately asking for police. If the vehicle has an SOS or eCall feature, it may provide another route for assistance.
Do not attempt to push the car, set out warning triangles, change a tyre or wave traffic around the vehicle. A lane could be closed by the road operator after receiving your report. The driver should tell emergency services exactly where the car is so responders can locate and protect it.
Where a safe exit route becomes available, follow emergency personnel’s instructions. Avoid sudden movements into live lanes. An elevated risk can arise at night, in rain, fog or near a bend where oncoming drivers may have little time to react.
Who to call and what information to give
999: For immediate danger, a live-lane breakdown, inability to exit safely, injury, a crash or a medical emergency. Ask for police and provide your location. National Highways 0300 123 5000: for road assistance and coordination on its England network. Breakdown recovery provider: for roadside recovery once you and passengers are safe and emergency services are informed when necessary.
An emergency roadside telephone is useful because it links to road operations and can help locate your position. On an emergency area, use the phone and follow the advice about leaving the refuge. Do not walk along the hard shoulder a long distance to find a phone if doing so is unsafe. Use your mobile or vehicle SOS function instead.
Location details that make your call more useful
- Motorway number, for example M1, M4 or M62.
- Whether you are travelling north, south, east or west; if unsure, state the direction of the last place you passed.
- Nearest junction number, service area, emergency refuge or named exit.
- Driver-location signs or marker-post numbers and letters, when visible from a safe position.
- Vehicle description and whether you are in a live lane, hard shoulder, verge or emergency area.
- Any trapped occupants, injuries, mobility needs, children or pets.
- Weather, darkness, fire, debris or other hazards that may make the location particularly dangerous.
If you do not know the junction, say what you can see. A phone map may give an approximate point, but road direction matters because the opposite carriageway can be inaccessible to response vehicles. Give the operator the best facts you know rather than guessing.
Children, disability, older passengers and drivers alone
Children in the back seats
Children should not get out on the traffic side. If you can safely exit, organise their movement through the safest door and quickly guide them behind a barrier. Keep them within reach and away from the vehicle and carriageway. If you cannot safely move the children, stay secured in the vehicle and call 999.
Someone cannot leave without help
The Highway Code recognises that disability and mobility limitations may prevent ordinary evacuation. Keep hazards on, stay belted in when exiting is unsafe and call 999 asking for police. Explain the person’s access needs, the position of the vehicle and the assistance required. Never improvise a dangerous wheelchair transfer on the edge of a live lane.
Travelling alone at night
Do not return to the car because it is cold or raining once you have reached a safe protected location. Give the recovery provider and road operator your position and that you are alone. Keep your phone charged and visible, but stay alert to traffic rather than concentrating continuously on the screen.
How different motorway layouts change the response
Traditional motorways may have a continuous hard shoulder. Some all-lane-running sections use emergency areas rather than a hard shoulder. Other high-speed roads have lay-bys or verges. The practical principle is the same: leave the high-speed traffic lanes when safe, move out of danger, and request help as early as necessary.
A red X on an overhead gantry means the lane is closed and should not be used. Drivers approaching a breakdown must obey signals and police or traffic officer directions. Do not assume passing vehicles will follow warnings, which is why waiting far away from the stopped car matters.
What changes in Scotland, Wales or Northern Ireland?
The British Highway Code guidance is designed for England, Scotland and Wales, but the road-operating organisations can differ. National Highways manages strategic roads in England rather than every motorway in the UK. In Northern Ireland, follow local government and police road-safety guidance. For a life-threatening emergency anywhere in the UK, call 999.
Common errors that make a breakdown more dangerous
- Placing a warning triangle on a motorway. The Highway Code explicitly says not to do this.
- Attempting a tyre change or engine repair by traffic. Request professional roadside support.
- Standing between the vehicle and traffic. A stationary car may be pushed by a collision.
- Crossing live motorway lanes to reach a barrier. Only leave by a genuinely safe path and follow emergency directions.
- Returning to a stranded car for bags, a coat or to charge a phone. Stay protected once safely clear.
- Believing that hazard lights make the car safe to remain in. Hazards warn drivers; they do not protect occupants from collision.
- Using an emergency area for a routine stop. These are reserved for emergency situations.
- Driving out of an emergency area without operator advice. The Highway Code requires using the provided phone and following directions.
What if there has also been a collision?
A crash with injury or immediate danger calls for 999 and emergency services. Give the number of injured people if known and do not put yourself into live traffic to inspect damage. Move uninjured people to a safe location when possible. Do not move seriously injured people unless immediate danger requires it and emergency responders advise an action.
Exchange details and arrange insurance or towing only once the scene is controlled and people are safe. Do not stop in another lane to take photographs. Responders may need a rolling roadblock, lane closure or controlled recovery, and they will tell you when access is permitted.
Before a long motorway journey: five-minute safety preparation
- Check tyres, warning lights, fuel or charge, windscreen and visible leaks before departure.
- Keep a charged phone and emergency contacts, including recovery membership or insurer assistance.
- Carry weather-appropriate clothing, drinking water and essential medication.
- Know what an SOS emergency area and a motorway location marker look like.
- Tell passengers what to do if they must exit away from traffic.
- Plan suitable rest stops and avoid driving when the vehicle is showing a serious fault.
- Ensure any special mobility or medical equipment has a realistic emergency plan.
- Review the current Highway Code before driving if you are unfamiliar with British motorways.
Frequently asked questions
Should I get out of the car on the motorway?
If it is safe and possible to exit on the side away from traffic and reach a protected place, yes. If the vehicle is in a live lane or you cannot safely leave, remain seat-belted with hazards on and call 999 immediately.
Do I put a warning triangle behind the car?
No. Warning triangles must not be placed on motorways.
Can I use the hard shoulder to change a tyre?
Do not attempt repairs beside live motorway traffic. Move clear of the vehicle and contact breakdown recovery.
What does an orange SOS sign mean?
It indicates an emergency area or emergency assistance point. Follow posted signs and use the phone if you have stopped there.
Should I call the AA, RAC or 999 first?
Call 999 first for immediate danger, being stranded in a live lane or inability to reach safety. Contact the relevant road operator and your recovery provider for recovery where the situation is not an immediate emergency.
How do I rejoin the motorway from an emergency area?
Use the emergency telephone and follow the operator’s instructions. The road operator may need to control the adjacent lane.
The rule that is easy to remember
Go left. Get safe. Get help. A breakdown does not need to become a second collision. People and safe positioning come before repairs, valuables or insurance details.
