How long does the automatic barrier arm take to drop at the parking lot?

The automatic barrier in the parking lot will drop 20 seconds after passing through. However, typically, it is triggered by the vehicle's presence; it will only lower when the car moves away.

The parking boom barrier uses inductive loops before and after the boom to detect if a vehicle has passed the barrier position. Upon detection, there is a brief delay before the barrier lowers. More advanced boom barriers also feature anti-crushing mechanisms, which may be used if the vehicle is smaller. Needless to say, those manually controlled boom barriers are a different matter.
