Incorrect Stop Signal Arm Border/FMVSS 131
A stop arm that does not meet the dimensional requirements may be less noticeable and thereby reduce the visibility of a stopped school bus, increasing the risk of a pedestrian injury.
Woodstock will notify owners, and will send those that purchased the stop arms a replacement border decal kit, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Woodstock at 1-845-247-3429.
