Fire on a Car: What to Do, Warning Signs and What Happens Next

What to Do Right Now if Your Car Is on Fire

Signal and pull over to a safe spot as quickly as you can, away from fuel pumps, buildings, dry grass and other vehicles if possible. Put the transmission in Park or engage the parking brake, and switch off the ignition to cut fuel flow and electrical power. Get everyone out immediately. Help children, older passengers and anyone with limited mobility first. Leave belongings behind. Move well away from the car and stay upwind and uphill if you can. Fire safety guidance commonly recommends a distance of at least 100 feet, and keep bystanders and traffic back as well. Call 911. Give your location, say that a vehicle is on fire, and mention if it is a hybrid or electric vehicle, if anyone is hurt, or if anyone is still inside. Do not return to the vehicle for any reason, even if the flames seem to die down.

Why You Should Not Open the Hood

Smoke or flames from the engine bay are a strong temptation to look underneath. Lifting the hood lets a rush of fresh air reach the fire, which can make it flare up suddenly toward your face and upper body. Leave the hood closed and let firefighters handle it. They have protective equipment and know how to approach a burning vehicle.

Should You Use a Fire Extinguisher?

Only if the fire is very small, everyone is already out and safe, and you have an extinguisher rated for the job. For a car, that generally means a unit rated for flammable liquids and electrical fires (Class B and C), and multipurpose ABC extinguishers are a common choice for vehicles. Stand back with your exit behind you, aim at the base of the flames rather than the smoke, and sweep side to side. If the fire does not go out quickly, or it is coming from under the hood, the fuel system or a battery pack, stop and move away. Never use water on a burning gasoline or oil fire, as it can spread the burning liquid.

Warning Signs That a Car May Catch Fire

Many vehicle fires give some warning before flames appear. Treat any of the following as a reason to pull over and investigate safely, or to have the car inspected promptly.

Smoke coming from under the hood, the wheels, the dashboard or the exhaust area. A smell of burning plastic, rubber or electrical insulation. A strong smell of gasoline or diesel when the car is running or parked. Fluid leaks under the car, especially fuel or oil near hot parts. Fuses that blow repeatedly, flickering lights or other unexplained electrical faults. The temperature gauge climbing into the red, or an overheating warning. Rapid changes in fuel level or oil level that you cannot explain. Cracked, loose or chafed wiring, or recent amateur wiring work. For hybrids and EVs: battery or high-voltage system warnings, hissing or popping sounds, or unusual smells from the battery area.

Common Causes of Vehicle Fires

A fire needs fuel, heat and oxygen, and a car contains all three. Most vehicle fires trace back to one of a few broad causes.

Fuel system leaks: gasoline or diesel escaping from lines, injectors or fittings and reaching a hot surface or spark. Electrical faults: damaged wiring, failed components, poor connections or improperly installed aftermarket accessories that overheat. Overheating: an engine or exhaust system running far hotter than normal can ignite nearby fluids or materials. Oil and other fluid leaks: engine oil, transmission fluid and some other fluids are combustible when they drip onto exhaust parts. Hot exhaust components: catalytic converters run very hot, and parking over dry grass or leaves can start a fire underneath the car. Collisions: crash damage can rupture fuel lines or damage battery packs and wiring. Poor maintenance or unaddressed recalls: worn parts, ignored leaks and open safety recalls increase the risk. Arson or items left in the car: deliberate fires happen, and lighters or some electronics left in a hot cabin can also be a hazard.

How Fires Differ by Powertrain

The basic response is the same for every vehicle: get out, get away, call 911. What differs is how the fire behaves and how it is put out. Risk levels also vary by specific model, age, condition and recall history, so these are general patterns rather than rankings.

Powertrain | Typical fire sources | How the fire tends to behave | What it means for you; Gasoline | Fuel leaks, electrical faults, overheating, hot exhaust | Can spread quickly once fuel is involved | Evacuate fast; do not open the hood; Diesel | Fuel and oil leaks, electrical faults, overheating | Diesel is harder to ignite than gasoline but burns intensely once alight | Same evacuation steps; Hybrid | Fuel system plus a high-voltage battery and wiring | Can combine a fuel fire with a battery fire | Tell 911 it is a hybrid; stay well back; Battery electric (EV) | Battery damage, manufacturing defects, charging faults, crashes | Battery fires can burn very hot, release toxic gases and reignite later | Do not attempt to extinguish; tell 911 it is an EV; keep far away

Electric Vehicle Battery Fires

EV and hybrid fires deserve a separate note because lithium-ion battery fires behave differently from fuel fires. A damaged or defective battery cell can enter thermal runaway, a self-sustaining chain reaction in which one overheating cell heats its neighbors. These fires can be very hard to extinguish, may require large amounts of water and specialized tactics from firefighters, and can release toxic and flammable gases.

A battery that appears to be out can reignite hours or even days later. That is why firefighters may monitor a burned EV, and why tow operators and storage yards often isolate damaged electric vehicles. If your EV has been in a fire or a significant crash, do not park it in a garage or near buildings until it has been assessed, and make sure everyone handling it knows it is an electric vehicle.

If an EV starts showing smoke, hissing or popping from the battery area while charging, stop the charge only if you can do so without approaching the car, get away from it, and call 911.

After the Fire Is Out

Let firefighters confirm the scene is safe before going anywhere near the vehicle. Seek medical attention for any burns or smoke inhalation, even if symptoms seem mild. Ask for the incident or report number from the fire department or police; your insurer will likely ask for it. Photograph the vehicle and the scene once it is safe, and note what happened before the fire. Contact your insurer promptly. In general, fire damage is covered under comprehensive coverage rather than liability-only policies, but the details depend on your specific policy. Arrange towing through your insurer or roadside assistance, and tell the tow operator if the car is a hybrid or EV. Do not try to drive a car that has had any fire, even a small one that was quickly put out, until a qualified technician has inspected it. Check whether your vehicle has any open recalls. If you believe a defect caused the fire, you can report it to the National Highway Traffic Safety Administration (NHTSA).

Reducing the Risk of a Car Fire

Check for open safety recalls on your vehicle regularly and have recall repairs done promptly. Follow the manufacturer's maintenance schedule, including inspections of fuel lines, hoses and wiring. Fix fluid leaks and burning smells right away rather than waiting. Have aftermarket electrical accessories, lighting or audio installed by qualified technicians. Avoid parking over dry grass or leaves, especially after driving. Do not carry spare fuel inside the cabin, and keep lighters and aerosol cans out of a hot interior. For EVs, use proper charging equipment, avoid damaged cables or adapters, and have the battery inspected after any impact to the underside of the car. Consider keeping a vehicle-appropriate fire extinguisher mounted securely in the car, not loose where it could roll around.

The Bottom Line

A fire in a car is a get-out-and-get-away emergency, not a repair problem. Stop safely, shut the car off, evacuate everyone, move far back and call 911, telling the dispatcher if the vehicle is a hybrid or EV. Keep the hood closed, use an extinguisher only on a tiny fire with a safe exit, and never go back for belongings. Paying attention to warning signs, keeping up with maintenance and recalls, and having the car inspected after any incident are the most practical ways to lower the chance of it happening at all.
