can you rental a uhaul to tow a car behind

[StNatalie]

No, you cannot legally or safely rent a U-Haul truck to tow a car behind it using a tow dolly or flatbed trailer. U-Haul's rental agreement explicitly prohibits this practice, known as "double towing" or "towing a trailer behind a towed vehicle." This setup creates a dangerously long and unstable combination that exceeds the designed capabilities of their trucks and violates most state laws.

The primary reason is safety. A U-Haul truck towing a car creates a very long wheelbase, making it difficult to control, especially during emergency maneuvers, lane changes, or in windy conditions. The truck's brakes, suspension, and transmission are not engineered to handle the stresses of stopping and controlling two heavy vehicles at once. This significantly increases the risk of a dangerous swaying motion (trailer fishtailing) or a jackknife situation.

Most states, including major ones like California, Texas, and Florida, have strict regulations against double towing for non-commercial drivers. Even in the few states where it might be technically legal under specific conditions, U-Haul's corporate policy universally forbids it to mitigate liability and ensure customer safety.

Your safe and approved alternative is to use a U-Haul Auto Transport or Auto Trailer. These are specifically designed to carry your car, either with its wheels on the ground (on a tow dolly) or completely off the ground (on a flatbed). You would then load your personal belongings into the U-Haul truck itself.

Consideration	Why It's Not Allowed	Safe Alternative
Vehicle Stability	High risk of trailer sway and jackknifing due to excessive length.	Auto Transport trailers are shorter and engineered for stability.
Braking Performance	Truck brakes are inadequate for stopping the combined weight safely.	Auto Transports have their own integrated braking systems.
Legal Compliance	Illegal for non-commercial drivers in the vast majority of states.	Using an Auto Transport is legal and compliant with rental terms.
Rental Agreement	Explicitly violates U-Haul's contract, voiding insurance coverage.	Auto Transport rental is an approved and insured service.
Mechanical Stress	Can cause severe damage to the truck's transmission and suspension.	Proper equipment is rated for the specific load, preventing damage.

Nope, that's a hard no from U-Haul. Their rules are super clear: you can't tow a trailer that's also towing something. It's a major safety hazard. The truck isn't built to handle that much weight and length, and it's actually illegal almost everywhere. You'd be risking an accident and voiding your rental insurance. Just rent one of their car trailers instead—it's what they're made for.

I looked into this for my own move last year. The U-Haul rep told me straight up it's against their policy. It's called double towing, and it turns the whole rig into a dangerous, unpredictable snake on the highway. The legal headache alone isn't worth it; most states ban it for regular drivers. Save yourself the trouble and get the right tool for the job: a dedicated U-Haul auto hauler for your car and a truck for your stuff.

Think of it from an engineering standpoint. A U-Haul truck's chassis, brakes, and powertrain are calibrated for a specific maximum load. Hooking up a car behind a tow dolly adds tremendous stress, exceeding design limits. The physics are simple: longer wheelbases are harder to control and stop. This isn't a gray area; it's a firm prohibition for clear safety reasons. The correct method is to use a single, purpose-built auto transport trailer to carry the vehicle.

Planning a big move and trying to simplify things? I get it. But towing a car behind a loaded U-Haul is one shortcut that will backfire. Beyond being against the rules, it's genuinely unsafe. The rental counter will not allow it, and if you managed it anyway, you'd be driving an unstable vehicle that's illegal in most places. The proven, worry-free solution is to use a U-Haul truck for your boxes and furniture and a separate U-Haul car trailer for your vehicle. It's the only way to ensure a safe and legal trip.
