Reversing (also known as backing up) is the process of driving a vehicle in the reverse direction in order to maneuver. Rear view mirrors are somewhat standard equipment for this endeavor. Reversing a vehicle is used as an intermediate step to complete a three point turn , J-turn , parallel park , or similar maneuver.
As a result of increased sales of full electric vehicle and hybrid electric vehicles in several countries, some members of the blind community have raised concerns about the noise reduction when those vehicles operate in all-electric mode, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and think quiet hybrids could pose an ...

Back-up beepers or an observer are required by OSHA for earth-moving vehicles with an obstructed view to the rear and no one on the ground to help guide the driver. [9] OSHA regulation 29 CFR Part 1926.601(b)(4) requires "a reverse signal alarm audible above surrounding noise level", but only when the motor vehicle has "an obstructed view to the rear".
The wagon-wheel effect is exploited in some engineering tasks, such as adjusting the timing of an engine. This is also done in some turntables for vinyl records. Since the pitch of music reproduction depends on rotation speed, these models have regular markings on the side of the rotating platter.
A bootleg turn is a driving maneuver intended to reverse the direction of travel of a forward-moving automobile by 180 degrees in a minimum amount of time while staying within the width of a two-lane road. [1] This maneuver is also known as a smuggler's turn, powerslide, or simply bootlegger.
The turn is achieved by transferring the momentum of the car by reversing quickly in a straight line then turning the wheel sharply while using a brake to lock the front wheels. The driver changes into a forward gear as the nose comes about.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
