On a vehicle equipped with electric park brakes, the park brake will not apply if the vehicle is in motion.

Electric park brakes are controlled by an electric motor and can be commanded by a switch or by automatic safety features. Some systems include functions like Auto Hold or hill-start assist that engage the brake to keep the car stationary, and in certain situations the parking brake can be applied while the vehicle is moving (for example during an emergency activation or if the driver deliberately engages the switch at low speed). Because of these possibilities, the statement that the park brake will not apply if the vehicle is in motion isn’t universally true. In many designs, engagement at very low speeds or under specific safety/fault conditions can occur, while at higher speeds the system will typically prevent abrupt engagement for safety.
