What should I do if I cannot safely leave my car after breaking down on a Northern Ireland motorway?

If you cannot safely leave a broken-down vehicle on a Northern Ireland motorway, keep hazard lights on, call emergency services or police and clearly explain that you are trapped in a live-traffic situation.

The Northern Ireland position should be checked against current nidirect/DfI guidance and the NI Highway Code. The Highway Code says leave only when you can safely get clear of the carriageway. A disabled occupant, live-lane stop or barrier configuration can make normal exit advice unsafe.

For this exact issue — “What should I do if I cannot safely leave my car after breaking down on a Northern Ireland motorway?” — the Northern Ireland motorway rule has to be applied with high-speed safety in mind. Check the live signs, lane status and whether you are dealing with normal driving, congestion or a genuine emergency. Hard shoulders, emergency areas and motorway lanes are controlled spaces, so actions that would be ordinary on a local road can be prohibited or extremely dangerous here.

Keep seat belts fastened if you must remain inside and follow emergency-service instructions rather than attempting a dangerous crossing. Keep evidence such as photographs, policy wording, vehicle plates or official notices where they could matter later; this is especially useful if an incident, fine or insurance question follows.
