{{For|the air combat maneuver also known as the "J-Turn"|Herbst maneuver}}
A '''J-Turn''' is a driving maneuver used to reverse a backwards-traveling vehicle so as to continue driving in the same direction, but with the vehicle pointed forward. The J-Turn is also called "[[moonshine]]r's turn", based on the elusive driving tactics used by [[rum-running|bootlegger]]s. A J-turn differs from a [[bootleg turn]] in that the vehicle starts out reversing.

This maneuver is also known as a "Rockford", referring to the TV show "[[The Rockford Files]]" due to the prevalent use of the stunt in the show.

==Technique==

The maneuver is performed by quickly turning the wheel to one side and using the foot brake to lock the front wheels while turning. The vehicle is shifted into a forward gear as the nose comes about.

In front-wheel drive vehicles the clutch must be pressed when performing the maneuver.

==World Record==
The narrowest J-Turn was performed in a [[Renault Twingo]], between barriers set 378 centimeters apart. The diagonal length of the car, 370 centimeters, meant stunt driver [[Terry Grant]] had only a gap of 4 centimeters on each side. This happened at the [[National Exhibition Centre]] in [[Birmingham]], [[UK]], at the Pistonheads show 11-13 January 2008.
