What to do if you run out of fuel on the road

It happens to careful drivers too: a jammed gauge, a longer gap between stations than expected, or a low-fuel light ignored one time too many. The good news is that running dry is almost always a fixable inconvenience rather than an emergency, provided you keep calm and put safety first. Here's how to handle it and get back on the road with minimum fuss.

First, get to safety

The moment the engine hesitates or the charge warning turns urgent, your priority shifts from reaching your destination to stopping safely. Don't fight a stumbling engine. Signal early, steer smoothly toward the hard shoulder, a lay-by, or the nearest safe verge, and use whatever momentum you have left to coast well clear of moving traffic before you lose power steering and brake assistance.

Switch on your hazard lights the instant you begin to slow, so drivers behind understand you are a developing problem. Try to stop somewhere straight and visible rather than on a blind bend or the crest of a hill, and steer the car as far from the live lane as the space allows.

Make yourself visible, then step clear

Once stopped, think about being seen and being out of harm's way. On a motorway or fast dual carriageway the safest place is usually out of the vehicle, behind the barrier, and away from the direction of traffic. Take everyone with you and leave pets in the car if you can't manage them safely.

• Hazards on, sidelights on in poor visibility or at night so the car reads as stationary.
• Wear a high-visibility vest before you step out if you have one, and keep it where you can reach it without walking into traffic.
• Exit on the side away from traffic: usually the passenger side, and don't stand between the car and oncoming vehicles.
• Warning triangles have their place, but not on motorways, where placing one puts you in danger. On a quiet road, set one well back to give others time to react.

Work out how far help is

With everyone safe, take a breath and assess. Open the map and find the nearest station or charger. Knowing the exact distance, and whether it is open and stocks your fuel or offers your connector, is what tells you whether this is a short walk with a can or a job for roadside assistance. For EV drivers, look for the nearest working charger with the right connector and check its recent status before pinning your hopes on it.

Getting moving again

There are really only three routes back onto the road, and the right one depends on where you are and what you drive.

• Breakdown or roadside cover: for most drivers this is the simplest and safest option. Recovery services will usually bring enough fuel to reach a station, or load the car onto a truck and take you to one. Have your location, membership details, and a description of the car ready when you call.
• A fuel can: only if a station is genuinely walkable and the route to it is safe: never along a motorway. Buy an approved container, carry the smallest sensible amount, and don't overfill. A few litres is enough to reach the pumps.
• EV recovery: there is no roadside equivalent of a jerry can. A flat battery almost always means a flatbed. Call your breakdown provider, explain it's an electric vehicle out of charge, and wait safely for recovery to the nearest working charger.

Restarting after you refuel

Getting fuel into the tank is not always the end of the story. Petrol engines generally restart without drama once there's fuel to draw on. Diesels are fussier: running a diesel completely dry can pull air into the fuel lines, and the engine may need several extra seconds of cranking, or a manual priming step using a pump on the fuel filter, before it fires. Crank in short bursts to avoid flattening the battery, and check your handbook, because some modern diesels self-prime and others do not.

Whatever you drive, fill up properly at the first proper opportunity rather than adding the bare minimum and hoping. A splash of fuel to reach the forecourt is fine; leaving with a quarter tank is far better than repeating the whole ordeal an hour later.

A real-world example

Picture a family driving home late on a motorway. The low-fuel light has been on for a while, but the next services are "only a few miles". The engine starts to surge on an incline. Instead of pressing on, the driver signals, eases onto the hard shoulder while there's still momentum, and puts the hazards on. Everyone climbs out on the passenger side, slips on the hi-vis vests kept in the door pocket, and moves behind the barrier. From there the driver checks the map, sees the services are too far to walk safely, and calls breakdown cover with an exact location. Twenty minutes of waiting in a safe spot replaces what could have been a dangerous walk along a live carriageway. Uncomfortable, yes, but never unsafe.

Make sure it doesn't happen again

Running out is almost entirely preventable, and the habits that prevent it are small. Treat the low-fuel warning as "act now", not "a while yet", and aim to refuel around a quarter of a tank rather than on fumes. Before a long or remote stretch, plan your stops in advance and don't assume the next station is open or has fuel: check first.

EV drivers benefit from the same discipline in a different form: plan charging stops around real-world range in cold weather or at speed, keep a comfortable buffer, and have a backup charger in mind in case the first is busy or out of service. A little planning turns a potential roadside drama into a non-event.
