How to Safely Transport a 5gal Gas Can in a Pickup Truck? | Rules That Work

Transport a 5-gallon gas can in a pickup bed upright, secured against tipping, and never fill it inside the truck.

Hauling gasoline in a pickup is routine, but the difference between safe and dangerous comes down to a few rules people skip. A loose can in the bed can slide, tip, and vent fumes into the cab—or worse. The core of safe transport is an approved container kept upright and tied down, with the fill-up done on the ground, not in the truck. Here’s what the rules actually require and how to set it up right.

What Kind Of Gas Can Is Legal To Transport?

Consumer containers and transport-rated cans are not the same thing, and the rules treat them differently. For consumer portable fuel containers, the Consumer Product Safety Commission (CPSC) requires compliance with ASTM F2517 packaging standards for child resistance, plus a flame mitigation device under the Portable Fuel Container Safety Act of 2020. Those rules apply to gasoline, kerosene, and diesel containers up to 8.45 gallons (32 L).

Transport adds another layer. The crucial distinction: an EPA-approved can is not automatically DOT-approved, and NFPA or CARB compliance does not equal DOT approval either. If you plan to haul regularly, look for a can explicitly labeled for DOT transport.

How To Secure A 5-Gallon Can In The Bed

The NY DOT guidance is direct: 5-gallon cans should be fastened in a vented box or lashed to the vehicle body with web straps, using two eyebolt anchor points per can with backing plates. For a consumer pickup, the same principle applies at smaller scale—the goal is zero movement.

• Place the can upright in the bed, never on its side.
• Strap it down with ratchet straps hooked to the bed’s tie-down points, not just wedged against cargo.
• Keep it away from anything that could puncture it—tools, lumber, or loose metal.
• Keep the cap and spout sealed; check the closure seals before loading.

How many cans are legal? That’s a state-agency limit, not universal law, but it’s a reasonable ceiling for any pickup hauling gasoline.

Can You Fill A Gas Can Inside The Truck Bed?

No. Gasoline should not be filled inside a vehicle or pickup bed.

After filling, place the can back in the bed upright and re-strap it. Never carry a filled can in the cab or passenger area—vapors can accumulate even from a sealed can, and a confined space turns a small leak into a real hazard. If the bed is enclosed with a cap, crack a vent or keep the can near the tailgate for airflow.

What Else Should You Know Before Hauling Gasoline?

One common mistake is assuming “approved for gasoline” means approved for road transport. CPSC’s rules govern how containers are sold; DOT rules govern how fuel moves. A consumer-grade can from a hardware store is fine for a short trip to the mower, but it is not automatically rated for sustained highway transport. If you haul fuel regularly, invest in a can built for that job.

Also avoid leaving containers loose in the bed for any length of time. Heat builds up in a closed bed, and pressure changes can push vapors past the seal. If you’re moving a serious quantity of fuel or doing this weekly, it’s worth checking whether your state’s DOT has specific rules like New York’s—most do not, but the safe practices are the same everywhere.
