Rock crawling

Rock crawling is an extreme form of off-road driving using specialized vehicles ranging from stock to highly modified, to overcome obstacles. In rock crawling, drivers typically drive highly modified four-wheel-drive vehicles such as trucks, Jeeps, and "buggies" over very harsh terrain. Driving locations include boulders, mountain foothills, rock piles, mountain trails, etc.

Rock crawling is about slow-speed, careful and precise driving, and high torque generated through large gear reductions (100:1 or more) in the vehicle's drivetrain. Rock crawlers often drive up, down and across obstacles that appear impassable.

Rock crawling competitions range from local events to national series. These consist of 100–200-yard (91–183 m) long courses with obstacles set up with gates, similar to a slalom ski race.
