Tyre Burst on the Motorway? What to Do in the First 60 Seconds
A blowout at 70mph sounds like a gunshot, the steering wheel jerks, and your instinct screams at you to brake. That instinct is the most dangerous thing in the car. Here is exactly what to do — in order.
Step 1: Do NOT slam the brakes
Hard braking with one destroyed tyre creates a massive imbalance between the wheels and is the number one cause of blowout spins. Instead:
- Grip the wheel firmly with both hands — the car will pull towards the burst tyre.
- Keep light pressure on the accelerator for a second or two. It feels wrong, but it stabilises the car before you let speed fall away naturally.
- Steer straight. Make only small, smooth corrections.
Step 2: Slow down gradually and move left
Once the car is stable, ease off the accelerator and let the drag of the flat tyre slow you down. Indicate left and cross lanes one at a time. Only brake gently once you are below roughly 30mph.
Step 3: Stop somewhere survivable
- On a motorway with a hard shoulder, stop as far left as possible with your wheels turned to the left and hazard lights on.
- On a smart motorway with no hard shoulder, aim for an orange Emergency Area (ERA). If you cannot reach one, our smart motorway survival guide covers the live-lane protocol.
- Exit through the passenger-side doors and wait behind the barrier — never sit in the car on a hard shoulder.
Step 4: Getting moving again
A burst tyre is never repairable — the sidewall and structure are destroyed. Sealant foam is useless, and a breakdown tow will only drop you at a garage that may be closed. The fastest route back onto the road is a mobile tyre fitter:
- Enter your registration on RescueFitter.co.uk — our DVLA-linked system identifies your exact tyre size.
- We locate a local 24/7 fitter with your size in stock.
- The new tyre is fitted and balanced at the roadside (or at the recovery point if you were in a live lane), and you drive away.
Note: fitters cannot work in live motorway lanes. If you are stranded in a live lane, call National Highways on 0300 123 5000 (or 999 if in danger) first — the fitter meets you at a safe location.
