Caution Gate Arm in Use One Vehicle at a Time Sign

For lots and garages with a lift arm, where only one car may pass each time the arm rises. It stops drivers from creeping through behind the car ahead and having the arm drop on their hood or roof. Parking garages, hospital lots, pay lots and gated communities post it at the arm. A black CAUTION band tops the yellow face.

Set it on a post or the pay station island just before the arm, facing incoming cars. Sign post, mounting hardware, and brackets are sold separately.
