How often should traffic control devices be inspected in a workzone?

The recommended frequency for inspecting traffic control devices in a work zone is before each shift. This practice is crucial to ensure that all devices such as cones, signs, barriers, and lights are in proper condition and positioned correctly to maintain safety for both workers and motorists. Inspections conducted before each shift allow for the immediate identification of any damage, displacement, or obsolescence of the devices, which can occur due to traffic, weather, or other factors over time. This proactive approach minimizes potential hazards and ensures that the traffic control measures are functioning effectively throughout the duration of the work period.

While daily inspections may seem sufficient, the dynamic nature of work zones necessitates more frequent checks to address any issues that arise that could compromise safety. Weekly inspections may overlook issues that could be addressed more promptly, and only inspecting when changes are made does not account for day-to-day variations that could affect traffic conditions and worker safety. Therefore, the protocol of inspecting devices before each shift aligns with best practices in traffic control to promote a safe work environment.
