In what situation should drivers exercise extra caution?

Extra caution should be exercised when workers are present on or near the roadway because their safety is at risk, as well as that of drivers and passengers. Work zones often have unpredictable conditions, such as changing traffic patterns and debris. Workers may be moving around, and drivers need to be alert to potential unexpected situations, such as workers stepping onto the roadway or equipment being in the way of traffic. Slow down, follow any temporary signs, and be prepared to stop if necessary when in such areas.

In contrast, situations like clear road conditions, absence of signage, or driving through residential areas generally have established expectations for vehicle behavior that don't require the same heightened level of awareness as active work zones do. While caution is always important in these scenarios, the presence of workers introduces additional hazards that necessitate greater vigilance.
