Which of the following is important in managing a work zone safely during maintenance activities?

Effective communication with drivers is crucial for managing a work zone safely during maintenance activities. This approach helps to ensure that drivers are aware of ongoing maintenance work, understand any lane closures or detours, and can adjust their speed and behavior accordingly. Clear communication can include using variable message signs, flaggers, and other methods to convey critical information about the work zone. This proactive engagement with drivers helps to reduce the risk of accidents and enhances the safety of both the maintenance workers and the traveling public.

In contrast, while signage is important, relying on excessive signage can create confusion and may not effectively convey information if it is not clear or direct. Barriers are essential for safety, but relying solely on them does not provide the necessary guidance to drivers. Lastly, limiting the number of workers can aid in reducing hazards, but it does not directly address the need for driver awareness and communication, which is critical for overall safety in a work zone.
