It is like a regular handbrake but without the central button and the ratchet which locks the lever into place when it is pulled up. Implication being the handbrake does not remain engaged when it is pulled up and unlocks the rear wheels the instant it is released. A driving technique used to deliberately slide a car sideways either for the purpose of making a very tight bend quickly, or for turning around well within the vehicle's own turning circle is called the handbrake turn. This technique is used in some types of motorsport, for example motorkhana, rallying, autotesting and drifting. The driver starts by using steering the car and transfer weight to the outside tires; the handbrake is then used to lock the rear wheels, thus raising the difficulty of adhesion between the tires and the road surface. To prevent the handbrake from stalling the engine in a rear – wheel drive manual transmission vehicle it is also necessary to operate the clutch. Fly – Off – Handbrake is primarily a technique used to take sharp turns in motorsport but can also be used for some other purposes such as stunt or pursuit driving. Parallel parking can be completed in a single swing of motion using the handbrake for stunt purposes. This technique is often demonstrated in car shows for demonstrating the vehicle's agility and the driver's control. In pursuit driving, the same can be technique can be used for turning the car around in the width of two lanes without using a three – point maneuver, for example to bewilder a pursuer. It can also be used to quickly make sharp bends.
