What is the usual speed limit adjustment in work zones?

Answer: D — Reduced speed limits for worker safety

In work zones, the speed limit is typically reduced to enhance the safety of both workers and drivers. These areas often feature construction activities, equipment, and workers who are vulnerable to traffic. By lowering the speed limit, the risk of accidents decreases, as drivers have more time to react to sudden changes or obstructions. This adjustment is crucial in protecting those who are working on the roads and ensuring a safer environment for everyone on the road. In contrast, increasing speed limits or making no changes at all in these areas would not effectively prioritize safety and could lead to more accidents or injuries. Similarly, raising speed limits under the assumption of smoother traffic flow overlooks the potential hazards presented by the construction work and the people involved.
