Possible outcomes

Caution

Get out of the line of traffic first

Turn on your hazard lights immediately. If the car can still move, steer it onto the hard shoulder or the nearest safe place. If it cannot move, stay buckled and call for help, but only leave the vehicle if staying inside is more dangerous. Never stand between your car and oncoming traffic.

Emergency

Smoke or fire: get away and call the fire service

Get everyone out and move well away from the vehicle, uphill and upwind if you can. Do not open the bonnet or go back for belongings. Call the fire service. Warn other traffic only if it is safe to do so.

Caution

Overheating: pull over and let it cool

Pull over safely and switch off the engine. Do not open the radiator cap or coolant reservoir while it is hot. Wait at least 20-30 minutes before checking anything. If it keeps overheating, do not keep driving; call for assistance.

Info

Likely a battery or starting problem

If the lights are dim or you hear a click, the battery is the likely cause. Do not repeatedly crank the engine. Call roadside assistance or ask for a jump start if you have cables and a willing helper. Note any warning lights for the mechanic.

Info

It cranks but will not start

It is probably fuel, spark or a sensor issue. Do not keep cranking until the battery dies; stop after two short attempts. Check you are not simply out of fuel. Call roadside assistance and describe the sound.

Info

Not sure? Call for roadside help

Describe the symptoms exactly: what you see, hear and smell, and which warning lights are on. Stay with the vehicle in a safe place until help arrives. Do not attempt repairs in traffic.
