How to Tow a Car With a Tow Dolly: Loading, Strapping and Drivetrain Rules
A two-wheel tow dolly lets you move a car behind a pickup, SUV or motorhome without a full trailer, but it is only safe when loading, strapping and drivetrain rules are followed in order. This guide walks through each stage, from hitch checks to unloading, and explains why the towed car's drive layout decides which end gets lifted.
What a Two-Wheel Tow Dolly Does and When It Is the Right Tool
A tow dolly is a short trailer with a single axle and two wheels, built to carry just one axle of the towed car. The lifted wheels sit in cradles on the dolly, which you reach by fold-out ramps or a tilting bed, while the other axle rolls on the pavement behind. Because only half the car is off the ground, a dolly is lighter and easier to store than a full car trailer, and it adds less weight to the tow vehicle's load.
The parts you will handle are the coupler and tongue at the front, the ramps, the tire straps or wheel nets that hold the lifted tires, the safety chains, and the lighting harness. A dolly suits moving a compact or midsize car on a relocation, or towing one behind an RV. The towed car's owner's manual and the dolly's own manual always override general advice. This guide covers hands-on use only, not shopping or rentals.
Pre-Tow Checks on the Tow Vehicle, Hitch and Dolly
Start with weight. Add the dolly's empty weight, printed on its data plate, to the towed car's curb weight from its door placard or manual, then compare the total with the tow vehicle's rated towing capacity. The hitch receiver and ball also need ratings that cover the load. Match the ball diameter to the size stamped on the coupler, close the latch fully, insert the locking pin, and confirm the dolly sits level once it is coupled.
Inspect the dolly itself before any car goes on. Inflate its tires to the pressure on the sidewall or data plate, spin and rock each wheel to feel for bearing play or roughness, and look for bent or cracked ramps. Replace any strap with cuts or fraying. Plug in the lighting harness and have a helper confirm the brake, turn and running lights work. A heavy-duty dolly carries more weight and may have wider cradles, but the tow vehicle's own limits still apply.
Loading Order: Getting the Car Onto the Dolly Safely
Couple the dolly to the tow vehicle first, on firm, level ground, with the tow vehicle in park and its parking brake set. Pull the ramps out fully and lock them. Line the car up straight behind the dolly with the wheels that will be lifted pointed dead ahead. A helper standing off to the side, never in the car's path, guides the driver while the car creeps up the ramps at walking pace, keeping both tires centered on the cradles.
Stop the moment the tires touch the wheel stops. Put the car in park or gear, set its parking brake for now, and get out to check that both tires sit squarely in the cradles. Then stow and secure the ramps or tilt bed. Loading alone or on a slope is a common cause of off-center or runaway loads. Back down and try again if the car sits crooked, a tire hangs past a cradle edge, or a ramp shifts during the climb.
Strapping, Wheel Nets and Safety Chains Step by Step
Lay each tire strap or wheel net over the top of the tread, hook the ends into the dolly's anchor points, and take up slack on the two sides in turns so the car stays centered instead of being pulled toward one side. Tighten until the webbing is snug with no visible sag and the ratchet is locked closed. Tie off or tuck the loose tail so it cannot flap in the wind or wrap around a spinning wheel.
Attach the dolly's safety chains to the frame or to the tow points named in the car's manual, crossing them underneath with enough slack for turns but not enough to drag. Release the car's parking brake, set the transmission as the manual directs, unlock the steering if the manual requires it, and keep the key somewhere secure. Shake the car firmly, walk around the whole rig, and stop after the first few miles to re-tighten straps that have settled.
Towing a Front-Wheel-Drive Car on a Dolly
For a front-wheel-drive car, the front wheels normally ride on the dolly. That lifts the driven wheels, so the transmission and axles stay still while the rear wheels simply roll freely like trailer wheels. The front is also usually the heavier end of these cars because the engine and transaxle sit there, so carrying it on the dolly puts more of the load on the dolly's axle and less on the car's rear tires and suspension.
Still check the owner's manual. It should say whether dolly towing is approved for that model, which transmission position to use, and whether the steering has to stay unlocked. Some front-wheel-drive models carry restrictions despite their layout, so the manual decides. Before leaving, set the rear tires to the pressure on the door placard and look under the rear for exhaust hangers, low trim or hitch hardware that could scrape once the nose is raised.
Rear-Wheel-Drive and All-Wheel-Drive Cars: Special Rules
A rear-wheel-drive car loaded nose-first leaves its driven wheels on the road, where they turn the driveshaft and parts of the transmission. In many automatic transmissions the fluid pump only runs with the engine, so those parts spin without proper lubrication and can be badly damaged. Some manuals allow towing backward with the rear wheels on the dolly. Others call for disconnecting the driveshaft, which is a job for a professional.
Towing backward carries its own risks. The front wheels now on the road must be locked or strapped straight, the weight balance shifts, and some manuals forbid it entirely. Most all-wheel-drive and four-wheel-drive vehicles should not go on a dolly at all unless the manual describes a specific procedure, because all four wheels are linked to the drivetrain. If the manual says no, says nothing, or is unclear, use a flatbed or professional transport.
Driving With a Loaded Dolly: Speed, Turns and Backing Up
Follow the dolly maker's speed limit or your state's speed limit for vehicles pulling trailers, whichever is lower, and slow down further in crosswinds, rain or on broken pavement. The combination takes noticeably longer to stop, so leave extra following distance. Take turns wider than usual so the towed car's rear wheels clear the curbs, and expect the car to swing out behind the dolly in tight spaces like parking lots and gas stations.
Backing up a loaded dolly is generally impractical: the rig pivots at two points and can jackknife quickly, damaging the car or the dolly. Pick pull-through gas pumps and parking spots so you never have to reverse. At every stop, check strap tension, chain position, dolly tire temperature, lights, and the car's tires and steering. Unload on level ground in reverse order, then inspect the car's tires and suspension before driving it away.
