Loading a car onto a U-Haul tow dolly can seem daunting, but with the right preparation and a clear understanding of the process, it’s a manageable task that can save you significant time and money when moving a vehicle. This comprehensive guide will walk you through every step, from initial checks to securing your vehicle, ensuring a safe and successful towing experience. Whether you’re relocating, transporting a non-running car, or just need to move a spare vehicle, mastering how to properly load a car onto a U-Haul tow dolly is an invaluable skill.
Understanding U-Haul Tow Dollies
Before you even think about loading, it’s crucial to understand what a tow dolly is and its intended use. A tow dolly is a two-wheeled trailer that lifts the front wheels of the towed vehicle off the ground, allowing the rear wheels to remain on the road. This makes it ideal for front-wheel-drive (FWD) cars, but specific considerations apply to rear-wheel-drive (RWD) and all-wheel-drive (AWD) vehicles.
What is a Tow Dolly?
A tow dolly typically features a pivot pan, which allows the towed vehicle’s front wheels to turn with the steering of the tow vehicle, reducing stress on the towed car’s steering components. It also includes integrated ramps for driving the vehicle onto the platform and heavy-duty straps to secure the tires. U-Haul’s specific design aims for ease of use and safety, but proper application is paramount.
When to Use a Tow Dolly vs. a Car Trailer
The choice between a tow dolly and a full car trailer depends largely on the vehicle being moved and the towing distance. A tow dolly is generally lighter, less expensive to rent, and easier to maneuver, making it suitable for shorter distances or when towing an FWD vehicle. For RWD cars, it often requires disconnecting the drive shaft to prevent transmission damage from the rear wheels spinning without lubrication. AWD vehicles usually require a full car trailer to lift all four wheels, as towing with only two wheels on the ground can severely damage the drivetrain. Always check your car’s owner’s manual for specific towing instructions.
Key Features of U-Haul Tow Dollies
U-Haul’s tow dollies are designed with user-friendly features. They typically have a low-profile design for easier loading a car onto a U-Haul tow dolly, robust tire straps that cinch down securely, and a safety chain system. The pivot pan feature is central to their design, allowing for better tracking behind the tow vehicle, which is a significant advantage over rigid tow bars that can put strain on the towed vehicle’s steering.
Essential Preparations Before Loading
Proper preparation is the cornerstone of a safe tow. Skipping any of these steps can lead to dangerous situations on the road, damage to your vehicles, or even legal issues. Take your time and ensure everything is in order.
Vehicle Compatibility Check
First, verify that both your tow vehicle and the vehicle being towed are compatible with a U-Haul tow dolly. U-Haul provides a comprehensive compatibility checker on their website (or at rental locations) that takes into account the curb weight, wheelbase, and type of drivetrain for both vehicles. This is crucial for safety and preventing mechanical damage. Do not attempt to tow a vehicle that exceeds the dolly’s weight capacity or your tow vehicle’s towing limits.
Checking Your Tow Vehicle (Capacity, Hitch, Lights)
Your tow vehicle must be adequately equipped. This means:
* Towing Capacity: Ensure your vehicle’s towing capacity exceeds the combined weight of the tow dolly and the vehicle you are loading a car onto a U-Haul tow dolly.
* Hitch: A properly installed hitch receiver with the correct ball size (typically 2-inch for U-Haul dollies) is essential.
* Wiring and Lights: The tow vehicle must have a working electrical connection (usually a 4-flat or 7-way connector) to power the tow dolly’s brake and signal lights. Test these before leaving.
* Tires: Inspect your tow vehicle’s tires for proper inflation and tread depth.
Gathering Necessary Tools and Supplies
While U-Haul provides the dolly, a few additional items will make the loading a car onto a U-Haul tow dolly process smoother and safer:
* Gloves: Protect your hands from grease and sharp edges.
* Flashlight: Essential if loading in low light conditions.
* Wheel Chocks: To secure the tow dolly while loading, preventing it from rolling.
* Small Pry Bar or Screwdriver: Can be helpful for loosening stubborn strap ratchets if needed.
* Owner’s Manual: For both vehicles, especially to check specific towing instructions.
Choosing a Safe Loading Location
Select a flat, level, and paved area with plenty of space. Avoid sloped surfaces, gravel, or soft ground, as these can make loading a car onto a U-Haul tow dolly unstable and dangerous. A parking lot or a wide, quiet street are good options. Ensure there’s enough room to maneuver both vehicles safely.
Step-by-Step Guide: How to Load a Car Onto a U-Haul Tow Dolly
This section provides the precise steps required to safely and effectively load a car onto a U-Haul tow dolly. Pay close attention to each detail to avoid mistakes.
Step 1: Position the Dolly and Prepare the Area
Before bringing the towed vehicle anywhere near the dolly, ensure the dolly itself is properly secured and ready.
Securing the Tow Dolly
Park your tow vehicle and the attached tow dolly on a flat, level surface. Engage the parking brake on your tow vehicle. Place wheel chocks behind the tow dolly’s wheels (the dolly itself, not the tow vehicle’s wheels). This prevents the dolly from shifting or rolling while you are loading a car onto a U-Haul tow dolly. The ramps should be laid out on the ground in front of the dolly.
Connecting the Tow Dolly to the Tow Vehicle
Ensure the tow dolly is securely hitched to your tow vehicle. The coupler should be fully seated over the hitch ball, and the latch firmly closed. Attach the safety chains crisscross underneath the hitch, connecting them to your tow vehicle’s frame or hitch receiver. Finally, connect the lighting harness from the dolly to your tow vehicle’s electrical connector. Test the brake lights, turn signals, and running lights before proceeding. If any lights aren’t working, troubleshoot immediately. This connection is critical for safety and legal compliance.
Step 2: Drive the Vehicle Onto the Dolly
This is often the most nerve-wracking part, but taking it slow and being precise will make it straightforward.
Aligning the Vehicle
Position the vehicle you intend to tow directly in front of the tow dolly, centered with the ramps. Leave enough space to make a smooth approach. Ensure the steering wheel is straight and the tires are aligned with the dolly’s ramps. If the car is non-operational, you’ll need assistance to push it into position.
Slow and Steady Approach
Slowly and carefully drive the vehicle up the ramps. Aim for the center of each ramp. Have someone spot for you if possible, guiding you with hand signals, especially if visibility is limited. Drive until the front wheels are fully seated in the cradles of the tow dolly. You should feel a slight resistance as the tires settle into position. Do not drive past the wheel stops. Overrunning the stops can damage the dolly or the vehicle.
Ensuring Correct Tire Placement
Once the vehicle is on the dolly, check that both front tires are fully and squarely within the wheel cradles. They should be centered side-to-side and resting against the front stops. This proper placement is vital for secure strapping and balanced towing.
Step 3: Secure the Vehicle
This is the most critical step for safe towing. The vehicle must be firmly secured to the dolly to prevent any movement during transit.
Applying the Wheel Straps
U-Haul tow dollies use over-the-tire straps with ratchets.
1. Drape the straps: Place each strap over the center of the front tire. Ensure the strap is flat and not twisted.
2. Feed through the ratchet: Feed the loose end of the strap through the ratchet mechanism, which is usually located on the dolly’s frame.
3. Crank until tight: Use the ratchet handle to crank the strap until it is extremely tight. The tire should be compressed slightly, and there should be no slack. Wiggle the car to ensure it doesn’t move. You may need to tighten the straps further after driving a short distance.
4. Secure excess strap: Secure any excess strap length so it doesn’t flap in the wind.
Engaging the Safety Chains (or Secondary Securing)
Many tow dollies, including U-Haul’s, come with secondary safety chains or straps that wrap around the vehicle’s frame or lower control arms. These act as a backup in case the primary wheel straps fail. Attach these chains securely, ensuring they are not dragging on the ground and have no excessive slack. Always refer to the specific instructions provided by U-Haul for your particular dolly model.
Steering Wheel and Parking Brake
For FWD vehicles, it is generally recommended to leave the steering wheel unlocked (ignition in the “ACC” position, if applicable) so the wheels can pivot with the dolly’s pan. Place the vehicle in park (P) or neutral (N) and release the parking brake. For RWD vehicles where the driveshaft is disconnected, leave the transmission in neutral and the parking brake off. If you are unable to disconnect the driveshaft for RWD vehicles or towing an AWD vehicle, a tow dolly is not appropriate.

Step 4: Final Checks Before Departure
Before hitting the road, perform a thorough final inspection.
Double-Checking All Connections and Straps
Walk around the entire setup. Check the hitch connection, safety chains, light harness, wheel chocks (remove them!), and especially the wheel straps and secondary safety chains. Give everything a good tug to ensure it’s tight. A loose strap can lead to disaster.
Testing Lights and Brakes
With the engine of your tow vehicle running, have someone observe as you test the brake lights, turn signals (left and right), and running lights of the tow dolly. All lights must be operational and clearly visible. Also, test the tow vehicle’s brakes while the dolly is attached to get a feel for the added weight.
Adjusting Mirrors
The added length and width of the tow dolly and towed vehicle will affect your visibility. Adjust your side mirrors to ensure you have a clear view down both sides of the entire setup. Consider using extended towing mirrors if your vehicle doesn’t offer adequate visibility.
Important Considerations for Safe Towing
Safe towing goes beyond just proper loading. It involves understanding the dynamics of towing and adapting your driving style accordingly.
Weight Distribution and Balance
A properly loaded vehicle on a tow dolly will be balanced. The majority of the towed vehicle’s weight should be over the dolly’s axle, with a portion of the tongue weight resting on the tow vehicle’s hitch. Incorrect weight distribution can cause sway, making the setup unstable and dangerous. Ensure the towed vehicle is centered on the dolly.
Driving with a Tow Dolly (Speed, Turns, Braking)
- Speed: Reduce your speed, especially on highways. Most states have lower speed limits for vehicles towing trailers.
- Turns: Make wider turns than usual to avoid clipping curbs or other vehicles with the dolly.
- Braking: Allow for significantly longer braking distances. The added weight means it takes more time and distance to stop. Apply brakes smoothly and gradually.
- Hills: Be aware that climbing and descending hills will put extra strain on your tow vehicle’s engine and brakes. Downshift on descents to use engine braking.
Regular Checks During Travel
During long trips, pull over periodically (every 50-100 miles or at fuel stops) to re-check all connections. This includes the hitch, safety chains, and especially the wheel straps. Straps can sometimes loosen due to vibration and road conditions. Feel the hubs of the tow dolly and the towed vehicle’s rear wheels for excessive heat, which could indicate bearing issues.
Fuel Efficiency and Towing
Expect a significant decrease in fuel economy when towing. The extra weight and aerodynamic drag will make your tow vehicle work harder. Plan your fuel stops accordingly.
Legal Requirements and Regulations
Familiarize yourself with the towing laws of the states you will be traveling through. These can vary regarding speed limits, lighting requirements, and even specific types of towed vehicles. Always err on the side of caution.
Troubleshooting Common Loading Issues
Even with careful preparation, you might encounter minor hitches when learning how to load a car onto a U-Haul tow dolly.
Difficulty Aligning
If you’re struggling to align the car on the ramps, don’t force it. Back off slowly, realign the car, and try again. Sometimes a slight adjustment in the angle of approach can make all the difference. Having a spotter is invaluable here.
Straps Not Tightening Properly
Ensure the strap is not twisted and is fed correctly through the ratchet mechanism. If the strap seems to slip or not get tight enough, check for debris in the ratchet or ensure the strap material isn’t damaged. Sometimes, a tire may need a slight adjustment in the cradle to allow for proper strap tension.
Car Not Centered
If the car is not perfectly centered after driving onto the dolly, you might need to slightly adjust its position. For minor adjustments, you might carefully push or pull the steering wheel a bit while the car is in neutral and secured. If it’s significantly off, it’s safer to partially unload and then realign and reload.
Unloading Your Vehicle from a U-Haul Tow Dolly
Unloading is essentially the reverse of loading, but it requires the same attention to detail.
Finding a Safe Unloading Spot
Just like loading, choose a flat, level, and safe area for unloading. Avoid busy streets or sloped driveways.
Reversing the Loading Steps
- Secure the Dolly: Apply wheel chocks to the dolly’s wheels.
- Release Straps and Chains: Loosen and remove the wheel straps and secondary safety chains. Carefully unclip them.
- Unlock Steering/Engage Parking Brake: If the steering was unlocked, lock it now (e.g., remove key). If the parking brake was off, engage it. Put the car in park.
- Back Off Slowly: Carefully and slowly back the towed vehicle off the dolly ramps. Again, a spotter can be very helpful. Once the car is entirely off the dolly, engage its parking brake.
- Remove Wheel Chocks: Once the car is safely off, remove the wheel chocks from the dolly.
Disconnecting the Dolly
After the vehicle is safely unloaded, you can disconnect the tow dolly from your tow vehicle by reversing the connection steps: unplug the lights, unclip the safety chains, and finally unlatch the coupler from the hitch ball. Store the dolly’s ramps and straps properly.
Safely loading a car onto a U-Haul tow dolly requires patience, attention to detail, and adherence to safety guidelines. By following these comprehensive steps, you can confidently transport your vehicle, knowing you’ve taken every precaution for a smooth journey. Remember, safety is paramount, and a methodical approach will ensure your vehicle arrives at its destination without incident.
