If your car catches fire, act fast and put people first: pull over and stop, switch off the engine, get everyone out and well clear, and call emergency services. Only attempt to fight a small, contained flame with an extinguisher if it is safe and you have a clear escape; never reopen a closed bonnet on a roaring engine fire. The single best preparation is carrying a charged unit within reach, so it pays to know the extinguisher worth keeping in your vehicle before you ever need it.
Stop, Signal, and Get Everyone Out
The moment you smell smoke, see flames, or notice the temperature gauge spiking with a burning odour, signal and pull over to the side of the road as safely as you can. Switch off the engine to cut the fuel supply, set the handbrake, and get every passenger out immediately. Do not waste time gathering belongings. Move everyone at least a safe distance away from the vehicle and upwind of the smoke, because toxic fumes from burning plastics and fluids are as dangerous as the flames themselves. People first, possessions never.
Call Emergency Services and Warn Others
Once you and your passengers are clear, call the fire and rescue service right away and give your location precisely. A car fire can spread to grass, other vehicles, or buildings, and it can produce thick smoke that endangers passing traffic. If you are on a busy road, warn approaching drivers as safely as you can, and keep bystanders back. Even if you think you can handle the flames, making the call first means help is already on the way if the situation worsens, which car fires often do within seconds.
When to Use an Extinguisher and When Not To
An extinguisher is only useful on a small, contained fire that you can approach safely with a clear path to retreat. If flames are already large, if the fire is under a closed bonnet, or if you would need to lean over the engine, stay back and let professionals handle it. Opening the bonnet on an engine fire feeds it a rush of oxygen and can send flames into your face. If you do fight a manageable fire, a mounted best car fire extinguisher kept within reach makes the difference between acting in seconds and not acting at all.
How to Aim and Discharge Correctly
If the fire is small and you choose to fight it, remember the basic technique: aim at the base of the flames, not the tips, because the base is the point at which the fuel is burning. Stand back a sensible distance, sweep the discharge across the base, and watch for the fire reigniting. For an engine bay fire that you cannot reach safely, you can sometimes direct an extinguisher through a gap such as the grille or a slightly cracked bonnet rather than fully opening it. The instant the fire grows beyond easy control, drop the extinguisher and retreat to safety.
After the Fire: Stay Clear and Report
Even once flames appear to be out, keep your distance. Smouldering wiring and hot fuel can reignite, and a damaged battery or fuel tank remains a hazard. Let the fire service confirm the vehicle is safe before anyone approaches. Afterwards, notify your insurer, document the scene if it is safe to photograph from a distance, and have the cause investigated so it does not repeat in a replacement vehicle. Then make sure your next car carries a working, properly mounted extinguisher from day one.
Frequently Asked Questions
Should I open the bonnet to fight an engine fire?
No, not fully. Opening the bonnet floods the fire with oxygen and can send flames toward you. If you must act, direct the extinguisher through the grille or a small gap. For anything beyond a tiny flame, stay clear and wait for the fire service.
How far away should I move from a burning car?
Move well clear, a good distance away and upwind of the smoke. Burning fluids, tyres, and the fuel tank create real hazards, and toxic fumes spread fast, so keep passengers and bystanders back rather than watching from close range.
Can a car fire be put out with water?
Water is a poor and sometimes dangerous choice for car fires, which usually involve fuel and electrical components. A dry powder extinguisher rated for those fire classes is far more effective and safer than throwing water onto burning fuel or live wiring.
The Bottom Line
If your car catches fire, the priorities never change: stop safely, get everyone out, move clear, and call for help before you think about fighting flames. Use an extinguisher only on a small, reachable fire with a clear escape, and never reopen a bonnet on a serious blaze. The best way to give yourself that option is preparation, so keep a charged, properly rated unit within arm’s reach and review a reliable extinguisher for your car today.
