A patent application from GM has been published, detailing a tailgate ramp support system for safely loading and unloading small vehicles from a pickup bed.

Once you line up the ATV with the truck, place those ramps ... It is best to attach your straps onto your ramps so that they do not get in the way during the loading process.

Dirt is flying! Narrator: If you've driven any one of the many highways crisscrossing the world, chances are you've seen one of these: a truck escape ramp. Some escape ramps slope upwards.

CHP officers shut down the ramp, and a SigAlert was issued at 2:30 p.m. because of the closure. As of 3:30 p.m., the CHP was still working on tow trucks to remove the pickup and the three cars.
