Make an unavailable seat obvious

School bus seat blocker straps.

A visible webbing strap runs down the center of the seat to show riders and staff that the seating position is not available.

Simple seat control

A clear visual marker—not another hard barrier.

The strap is positioned over the seat where it remains easy to see during loading and route checks. “DO NOT SIT” lettering identifies the unavailable position without relying on a loose sign or temporary paper notice.

Standard configurations use black or red webbing with white or red applied-vinyl or embroidered lettering. A bilingual version is also available.

A seat blocker is a seating-position marker. It is not an occupant restraint and does not replace the transportation provider’s seating policy, supervision, or required securement equipment.

Built as webbing

Made to look like part of the seating setup.

The narrow webbing format keeps the message centered on the seat and visible without covering the entire seating surface.
