Which factor is crucial in reducing accidents in a work zone?

Adhering to posted signs and signals is crucial in reducing accidents in a work zone because these signs and signals are specifically designed to inform drivers about conditions that may be different from normal traffic situations. They provide essential information about speed limits, lane closures, detours, and other hazards associated with construction or maintenance activities. When drivers follow these signs and signals, they can adjust their behavior accordingly, leading to a safer environment for both themselves and the workers present.

In work zones, the likelihood of incidents increases due to unfamiliar conditions, so clear communication through signage is vital. By ensuring that signs and signals are visible and adhered to, the risk of accidents can be significantly minimized. Additionally, compliance with these instructions helps to create a predictable driving environment, which can further enhance safety in the area.
