An emergency brake lock assembly that locks an emergency brake actuator in an engaged position to prevent the vehicle from moving while a lift assembly contained on the vehicle is being operated. The emergency brake lock assembly includes an emergency brake switch that is positioned to detect movement of the emergency brake actuator between an engaged position and a disengaged position. When the emergency brake actuator is in the engaged position, the emergency brake switch generates a brake engaged signal. An auxiliary door switch is positioned to detect the movement of an auxiliary door contained on the vehicle. When the auxiliary door opens, the auxiliary door switch generates a door open signal. Upon receiving both the door open signal and the brake engaged signal, a solenoid actuator moves a locking member to a locked position to retain the emergency brake actuator in the engaged position. The lift assembly positioned in the auxiliary door is energized only when the auxiliary door is open and the emergency brake actuator is locked in the engaged position, preventing the vehicle from moving during lift operations.
