Abstract: A gear selector lock structure is provided and is operative to unlock the gear selector of a vehicle against movement from the non-drive position to the drive position thereof when the lock structure is in the locked position. The lock structure is spring biased toward the locked position and an electric solenoid is operatively associated with the gear lock structure for shifting the latter from the locked position to the unlocked position when the solenoid is electrically actuated. The solenoid is electrically connected to the brake light circuit of the associated vehicle and is, therefore, actuated when the brake pedal of the vehicle is moved from the brake release position to the brake applied position.
