A Flatbed Tow Carries the Car Instead of Pulling It
On a flatbed, your vehicle rides rather than rolls. The bed tilts down to the road, the car is winched or driven up onto the deck, and all four wheels sit on the truck, strapped or chained down with nothing touching pavement. Operators call these rollbacks or car carriers.
Because no wheel is turning, nothing in the transmission or the differential is spinning during the trip. That single fact is why flatbed towing is the default for vehicles that should not be towed on their own wheels at all, for cars with front-end or suspension damage, and for anything low, collectible or expensive. The trade-off is footprint: a carrier needs length behind it to tilt the bed and clear room to work.
A Wheel Lift Raises One Axle and Tows on the Other Two Wheels
A wheel lift slides a metal yoke under one pair of wheels, lifts that axle clear of the road, and tows the vehicle with the remaining two wheels rolling behind. UDOT's incident management trucks carry exactly this setup, which crews call a stinger, and they use it to pull disabled vehicles a short distance out of live travel lanes to somewhere safer.
That is the wheel lift's genuine strength. It is fast, it needs very little setup, and it fits into places a carrier simply cannot enter, which is why wheel lift towing is what clears a blocked lane or backs into a tight garage. It also means two wheels are turning for the whole tow, and that is where its limits begin.
