Burst tyreThe A41 bypass and the M25
If the car can still be driven slowly and safely, leave the A41 at the next exit and stop on a side road or in a car park. On the M25, use the next junction or services; junction 20, reached along the A41, is the nearest to the town.
If the car cannot move, wait behind a barrier if there is one, and call your breakdown cover, or National Highways on 0300 123 5000 on a motorway. Call 999 if anyone is in danger. When the car has been taken somewhere safe, call us with its location.
