can you put jerry cans in your car

Yes, you can transport Jerry cans in your car, but it is a significant safety risk that requires strict adherence to specific handling and legal guidelines. The primary dangers are fume accumulation, which can lead to poisoning or explosion, and fuel spillage, a major fire hazard. For safe transport, the absolute rule is to never carry a gasoline-filled Jerry can inside the passenger cabin of any vehicle, including the trunk of a car.

The only safe method is to secure the can in the bed of a pickup truck or on an external cargo carrier attached to an SUV or hatchback. Even then, the container must be a certified, DOT-approved fuel can that is specifically designed for gasoline transport. These containers are built to vent pressure safely and are less likely to leak. Before driving, ensure the seal is tight and the can is placed upright in a stable, well-ventilated area, secured with straps to prevent it from tipping over.

It's also crucial to be aware of local and state fire codes, which often limit the amount of fuel you can transport for non-commercial purposes, typically to around 5-10 gallons. For long-term fuel needs, such as for overlanding, investing in a professionally installed, permanent auxiliary fuel tank is a far safer alternative.

Safety Consideration	Key Action/Requirement	Rationale
Location	Transport in pickup bed or on external carrier only.	Prevents flammable vapor buildup inside the vehicle.
Container Type	Use DOT-approved, properly labeled Jerry can.	Ensures safe pressure venting and reduces leak risk.
Securement	Upright position, strapped down to prevent movement.	Avoids spills and potential impact damage.
Ventilation	Transport in a well-ventilated, open area.	Dissipates fumes away from ignition sources.
Legal Limits	Check state laws; typically 5-10 gallons max for personal use.	Avoids fines and complies with fire safety regulations.

I’d strongly advise against putting it inside your car. The smell of gas will soak into your upholstery and make the cabin unbearable for weeks. More importantly, those fumes are toxic and highly flammable. If you absolutely must carry extra fuel, strap a proper safety can to a hitch-mounted cargo carrier. It’s the only way to do it without turning your car into a hazard.

From a practical standpoint, the answer is no for passenger vehicles. The risk of a small leak or even just fumes building up is too high. Your best bet is a pickup truck bed. If you don’t have a truck, consider your actual need. For most road trips, planning your gas stops is safer and easier than hauling extra fuel. It’s one less thing to worry about.

Think of it this way: your car’s cabin is a sealed box. Gasoline vapors are heavier than air and can pool on the floor. A single spark from a seat motor, a light switch, or even static electricity could ignite them. It’s a preventable disaster. I only use a Jerry can for my lawnmower gas, and even then, I transport it in the trunk of my sedan for the short trip home, with all the windows rolled down.

I learned this the hard way on a camping trip. We put a sealed Jerry can in the back of our SUV, and within an hour, the headache from the fumes was unbelievable. We had to pull over and air everything out. It was a stupid risk. Now, if we need extra fuel for a remote journey, we use a trailer or rent a vehicle with an external storage option. The convenience is never worth the danger.
