Steel anti-rollback speed bump

HERSE anti-return spike strip to deter drivers from making U-turns. Made of steel, coated in yellow epoxy paint with anti-slip patterns. Equipped with 9 stainless steel teeth that lower when a vehicle passes in the correct direction and remain raised in the opposite direction. Option to lock the teeth. Do not drive over the spike strip. For everyone's safety, we recommend installing warning signs (ab2 = speed bump + b14 = speed limit) and speed bumps before the spike strip to reduce vehicle speed. Be cautious with children. Delivered with fasteners and tooth unlocking keys. Speed bump optional.
