Brake test

From Wikipedia, the free encyclopedia

A brake test, also known as a brake check, occurs when a driver deliberately brakes very hard in front of another driver who is tailgating, causing the second driver to swerve or otherwise react quickly to avoid an accident. Often, a brake check also refers to simply pressing the brakes hard enough to activate the brake lights, signaling to the other driver that an increased space cushion is needed.

Brake testing and tailgating are examples of aggressive driving, and both may be punishable as vehicular assault,[1] careless or reckless driving, or vehicular homicide if death occurs.

Because of the aggressive and dangerous nature of this move in motor sports, a driver who makes such a move is often penalized. Penalties given for such actions can vary from time penalties, to exclusion from a race or event.
