In a normal turn, rear wheels follow the front ones because resistance to motion in the forward direction (in which the wheels turn) is significantly less than in the sideways direction. The latter provides the centripetal force that makes the rear end of the car follow the turn. When the driver locks the rear wheels with the handbrake, both ...
Drivers of cars with a handbrake connected to the rear wheels can enter a controlled turning skid by employing the handbrake, locking the wheels, and turning the steering wheel sharply in either direction. This maneuver can also be called a bootleg turn, but is more precisely described as a handbrake turn. Using the handbrake to break the ...

[2] [3]While automatic transmission vehicles have a "Park" gear that immobilizes the transmission, it is still recommended to use the parking brake, as the parking pawl in the gearbox could fail due to stress or another vehicle striking the car ...
The locking knob on the hand brake is usually replaced with a spin turn knob; this stops the hand brake locking on when pulled. Nearly all drivers move the hand brake location or add an extra hydraulic hand brake actuator for greater braking force.

The second method is to extend the right arm perpendicular to the body, pointing in the same direction as the intended turn.
