What is a common hazard for workers in a work zone?

Answer: B — Unpredictable traffic flow

Unpredictable traffic flow is a significant hazard for workers in a work zone. This situation arises when vehicles are diverted, detoured, or otherwise rerouted, which can lead to erratic driving behavior from motorists. Drivers may not expect to encounter construction zones or changing traffic patterns, causing them to react in unexpected ways. The presence of construction equipment, machinery, and other workers in close proximity to moving vehicles adds to the potential for accidents. Thus, managing traffic flow safely and effectively is crucial to protect the health and safety of workers on-site. Adequate traffic control measures, such as signage, cones, and flaggers, must be implemented to mitigate the risks associated with unpredictable traffic.
