There are several types of tow trucks in operation today, from the simplest to the very specialized.

From this concept, an axle-mounted tow truck was lowered, which was equipped with a single clamp that could lift the front end of the damaged vehicle into the air for easy towing. The lifting mechanism is actuated hydraulically or pneumatically. This is probably the fastest way to drag and is often used in motion control.
Flat boards are used for pulling long distances. The flat board offers room for the entire handicap vehicle. This is accomplished by lowering a flat metal surface to the ground allowing the damaged vehicle to be towed from the back of the truck. There are also various tow truck combinations described above.
