What to Do If Your Car Breaks Down in Northern Ireland

A vehicle breakdown can happen on a city street, a rural road or a motorway in Northern Ireland. The immediate priority is not diagnosing the fault. It is reducing danger to the occupants and other road users before arranging assistance. The safest next step depends on where the vehicle has stopped.

If the vehicle can still move

If possible, get off the carriageway and stop in a safe, legal location away from moving traffic. Switch on hazard warning lights if the vehicle is obstructing the road. Keep side lights on when it is dark or visibility is poor. Avoid stopping on a bend or immediately after a hill if you can safely continue to a clearer location.

Once stopped, secure the vehicle and assess whether everyone can leave safely. If you are beside fast-moving traffic, do not stand between the vehicle and the road. Keep passengers clear of the traffic and avoid opening doors into passing vehicles.

Warning other drivers

On an ordinary road, the Northern Ireland Highway Code advises placing a warning triangle at least 45 metres behind a broken-down vehicle on the same side of the road, where it can be done safely. Never place a warning triangle on a motorway. Do not risk walking into traffic simply to set one out.

On a motorway, use an emergency area or hard shoulder if you can reach one safely and follow the specific safety guidance for that location. Motorway traffic creates different risks from a quiet lane. If it is unsafe to exit or move away from the vehicle, seek urgent professional guidance rather than attempting a roadside repair.

Getting help and giving your location

Contact a breakdown assistance provider or the vehicle hire contact specified in your agreement. Give the road number, travel direction, nearest junction or identifiable landmark and a description of the fault. A phone's map position can help, but do not operate it while driving.

Use 999 or 112 for a genuine emergency, such as immediate danger to life or a serious collision. Ordinary mechanical problems without an immediate emergency should be dealt with through breakdown assistance.

If the car is hired, ask what actions are authorised before arranging recovery or repair independently. Make a note of the vehicle registration and the location where assistance is needed so the handover is unambiguous. Keep records of the incident and any instructions received. Even where the fault seems minor, do not resume driving until the vehicle can be operated safely.
