What is BRAKE TEST? What does BRAKE TEST mean? BRAKE TEST meaning - BRAKE TEST definition - BRAKE TEST explanation.<br /><br />A brake test, also known as a brake check, occurs when a driver deliberately brakes very hard in front of another driver who is very closely behind, 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.<br /><br />Brake testing and tailgating are examples of aggressive driving, and both may be punishable as vehicular assault, careless or reckless driving, or vehicular homicide if death occurs.<br /><br />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.
