Safety first
Safety first
If a tyre fails and the car can still be driven safely, get it off the road into a side road, a lay-by or a car park. A lay-by on a fast road is a place to stop safely, not somewhere we can work; we come to the car once it is on a side street or in a car park. On a busy road or dual carriageway, do not try to change the wheel yourself; call your breakdown cover, or 999 if the car is somewhere dangerous. We never work on the carriageway of a motorway or main road, on a hard shoulder, in a smart motorway emergency area or on a slip road.
Road operator: Transport for London (London) / National Highways (trunk sections). For its sections, the National Highways contact centre is on 0300 123 5000; in an emergency, call 999.
In London, parts of the road are red routes. We cannot stop or work on a red route; the car needs to be on a side street or private ground first.
