Yes, you must lock the steering wheel when using a tow dolly. Failure to do so allows the front wheels to turn, which can cause the car's body to collide with the dolly's fenders during sharp turns or lane changes, resulting in significant cosmetic and structural damage. This is not a recommendation but a critical safety and operational requirement.
The primary reason is to prevent the towed vehicle's front end from swinging. A unlocked steering wheel is the single greatest risk for causing accident damage with a dolly. When the towing vehicle turns, inertia wants to keep the towed car moving straight. If the steering wheel is free, the front wheels will pivot on the dolly, allowing the car's fenders, doors, or quarter panels to smash into the dolly's own fenders or structure. Repair costs for such collisions often exceed thousands of dollars.
Industry data from major rental providers like U-Haul indicates that improper steering wheel securing is a leading contributor to tow dolly incidents. Their guidelines explicitly mandate it. The practice ensures dolly stability, particularly with common swivel-type dollies, by keeping the entire assembly predictably aligned behind the tow vehicle.
If your vehicle's steering column has a physical lock (turn the key to "lock" or "off" and remove it), use it. This is the most secure method. For vehicles without a locking column, you must manually secure the wheel.
Consequences of skipping this step are severe and immediate. Beyond body damage, a freely turning wheel can cause the dolly to fishtail or jackknife, especially during evasive maneuvers or on uneven roads, risking loss of control. It also places extreme stress on the dolly's tire straps and the towed car's suspension components.
Essential supplementary steps are non-negotiable. Always fully release the towed vehicle's parking brake. After initial setup, pull the dolly forward about 100 feet in a straight line, stop, and double-check that all tire straps are tight and the steering remains fixed. Re-check after the first 5 miles of travel, and then at every fuel stop or approximately every 50 miles. Never attempt to reverse with a tow dolly attached; the geometry will force the dolly tires to skid sideways, likely damaging the dolly, the towed car's tires, and the tow vehicle's hitch.

















I learned this the hard way last summer. I was towing my sedan cross-country and thought the steering lock was enough. I didn't double-check it was actually engaged. During a highway merge, I felt a huge jolt. Pulled over to find my front passenger door crunched against the dolly frame. A $2,800 mistake. Now, I'm paranoid about it. I don't just turn the key. I physically try to turn the wheel with all my might before I away. Then I do the seatbelt trick as a backup, every single time. That visual check isn't enough—you need to test it.

As someone who runs an RV transport service, I've towed hundreds of vehicles on dollies. The steering wheel is always job one. My process is ritual: Lock the column if it has it. If not, I use a specific, heavy-duty ratchet strap from the wheel to the brake pedal. It's faster and more reliable than a seatbelt in my experience. Then, the critical part most DIYers miss: the first few miles. You need to make a couple of gentle left and right turns in a parking lot, stop, and inspect. You're looking for any shift or movement in the steering. If it budged, you didn't secure it tightly enough. That initial test drive catches 99% of problems before they become road disasters.

Think of it like this: the dolly lifts the front wheels off the ground, so they're free to spin and turn. If you let the steering wheel move, those front wheels become casters, like on an office chair. When you turn the tow vehicle, the car's body wants to go straight, but the wheels on the dolly can swing sideways. The metal fender of your car and the metal frame of the dolly are now on a collision course. It's simple physics. Securing the wheel removes that swivel point. Just always remember to unlock it before you try to drive the car again off the dolly. It sounds obvious, but in the moment of arrival, people forget.

Beyond preventing crashes, locking the wheel is about protecting your equipment's lifespan. A constantly turning steering wheel while in tow puts unnecessary strain on the vehicle's steering rack and tie rods, even with the engine off. For the dolly, erratic forces from an unsecured wheel accelerate wear on its pivot points and bearings. My checklist always includes: 1) Key to "lock" or "off", 2) Seatbelt cinched through wheel (pull tight, click, pull tight again on the belt itself), 3) Parking brake 100% OFF (touch the lever to confirm), 4) Transmission in park or gear. Before moving, I have my partner watch the dolly and car front end as I make a sharp left and right turn in a safe area. Visual confirmation is the final step. This isn't just about following a rule; it's a systematic method to ensure a predictable, safe tow every time.
