JP 10 was a jeep owned by Jurassic Park. The Jeep was first used by Robert Muldoon and Ellie Sattler during their search for the rest of the group. It differed from other Jeeps used by the park in that it lacked a safety bar/roll cage in case of turnovers and it also lacked a roof. During the Tyrannosaurus rex escape, the vehicle's top as well as windshield were damaged by a low-hanging branch. It was later used by all of the surviving visitors to escape from Jurassic Park.
