Repairing and Maintaining Traffic Safety Equipment

Attenuators, arrow boards, and message boards need upkeep to stay reliable and compliant. A steady maintenance program keeps equipment ready and crews protected.

Traffic safety equipment protects people, so its upkeep is not optional. An attenuator that fails to deploy or a board with dead lamps puts crews and drivers at risk. A steady maintenance program is what keeps the gear ready and compliant.

What needs regular attention

• Attenuator deployment and hydraulics, tested through the full raise and lower cycle.
• Impact hardware such as blades or cartridges, inspected and replaced after any hit.
• Arrow board and message board lamps, checked for dead or dim elements before each shift.

Repair and re-certification

A repair on a crash-rated device is only complete when the unit is confirmed to still meet its standard. Re-certification verifies that a repaired attenuator performs the way its FHWA eligibility letter says it should. Pairing repair with re-certification is how a unit returns to service with its rating intact.
