ABSTRACT:
A canopy assembly for use at fast food restaurants or the like and beneath which vehicles normally drive. An over-height impact bar is carried by a frame of the canopy assembly and when struck, first energizes an alarm and then travels over a first lost motion distance enabling a driver to react to the alarm and stop the vehicle before it strikes the canopy. Should the driver not stop, the impact bar travels a second lost motion distance to cause a latch to be unlatched and permit the assembly to be swung by the oncoming vehicle clear of its path of movement.
