Yes, you can transport a car inside a U-Haul box truck, provided you select a truck model large enough to accommodate the vehicle's dimensions and weight. The most critical factor is the internal cargo space length and height. For a standard sedan, you will likely need at least a 20-foot truck. The process requires careful , proper equipment like ramps, and securement to ensure safety.
The primary challenge is the ramp angle and ground clearance. U-Haul box trucks are not designed like car carriers; their ramps are steep. A low-slung sports car will likely scrape or get high-centered. A vehicle with higher ground clearance, like an SUV, is a better candidate. You must also consider the gross vehicle weight rating (GVWR). The combined weight of the box truck, your car, and all other cargo must not exceed the truck's maximum capacity.
Loading requires a spotter and a slow, careful approach. Once inside, the car must be securely strapped down using wheel nets or axle straps to prevent it from rolling or shifting during transit. The parking brake should be engaged, and the transmission left in park (or gear for a manual).
Here’s a comparison of common U-Haul truck models and their suitability for car transport:
| U-Haul Truck Model | Interior Length (ft) | Interior Height (ft) | Suitable for a Standard Sedan? | Key Considerations |
|---|---|---|---|---|
| 10' Truck | 9'11" | 5'7" | No | Too short and low for virtually any car. |
| 15' Truck | 15' | 6' | Unlikely | Length might be borderline for a small car, but low height is a major issue. |
| 20' Truck | 19'10" | 7'5" | Yes (with caution) | A standard sedan (approx. 15-16 ft long) can fit. Check height clearance. |
| 26' Truck | 26' | 8'2" | Yes (ideal) | Ample space for a sedan and additional household goods. |
While possible, this method is riskier than using a dedicated car trailer or auto transport service. It's best suited for moving a car a relatively short distance as part of a larger household move.

I helped my brother do this last year. It's a tight squeeze, even in a big 26-footer. The ramp is the scariest part—it's super steep. We used his old Cherokee, which handled the angle fine, but a lower car would have scraped badly. The main thing is tying it down inside. We used ratchet straps on all four wheels to make sure it didn't budge. It worked, but it's a lot of work compared to just towing a dolly.

Technically feasible, but logistically complex. The primary constraints are dimensional and weight-based. You must confirm the cargo bay's cubic volume exceeds the vehicle's envelope, with particular attention to the ramp's angle of approach. Furthermore, the vehicle's curb weight, plus the weight of all other cargo, must not violate the truck's payload capacity. Securement is non-negotiable; professional-grade wheel straps are required to immobilize the vehicle within the cargo area, as relying on the parking brake alone is insufficient for safe transport.

Sure, if you get a big enough truck. But honestly, unless you're already renting a massive U-Haul to move your entire house and just need to get the car to the same place, it's not the easiest way. The ramps aren't made for cars, so you have to be really careful not to damage the underside. For the cost and hassle of getting the right equipment and doing it safely, you're often better off just renting a proper auto transport trailer from U-Haul itself. It's lower to the ground and designed for the job.

You can, but it's all about the specifics. What kind of car are we talking about? A Cooper is a very different story than a full-size pickup truck. Measure your car's length, width, and height first. Then, call U-Haul and ask for the exact interior dimensions of the truck you're considering. Don't guess. Also, ask about their ramp weight capacity and if they have any specific rules against loading vehicles. It’s better to spend ten minutes on the phone than to get stuck with a truck that doesn’t work.
