A height restrictor, height barrier, or height restriction barrier is a horizontal barrier mounted at the maximum allowed height, preventing taller vehicles from crossing. It is an artificial barrier. It may be placed some distance before something more substantial that imposes this limit (such as a roof), or may be used to enforce legal vehicle restrictions. Height restrictors can be found in front of underpasses, covered bridges, drive-throughs with overhanging roofs, parking garage entrances, and overground parking lots. The maximum height is usually posted either on the barrier itself or on a nearby sign.

How to map

Add the tag barrier=height_restrictor to a node along the affected highway=* way. Set maxheight=* to the posted maximum height on this node. Also split the way at this node and tag maxheight=* on the way after the node.
