An Army truck towing a wrecker jack-knifed and caused damage to both vehicles. How many units are involved, and how are they recorded?
The towed vehicle is considered part of the towing vehicle, the same as a trailer, making this a one-unit crash. Record information on the towed vehicle in the remark section. If there is an occupant behind the steering wheel of the towed vehicle, record them as a passenger in Unit #1, and position number one, the same as the towing vehicle driver.
