The reduced speed in work zones is for the safety of both motorists and workers. Slower speeds give drivers more time to safely negotiate work zones. About 85 percent of work zone fatalities are motorists.

A driver must always obey the posted work zone speed limit. Standard speed limits may be reduced due to the presence of workers or because normal driving conditions do not exist in a work zone. There may be narrow lanes, drop-offs between lanes or at the edge of pavement, lane closures, or construction equipment or obstructions near open lanes of traffic. The speed limit may be further reduced when workers are present.
