When driving in an active work zone, what must drivers do?

When driving in an active work zone, it is essential for drivers to reduce their speed, as this is a critical safety measure to ensure the safety of both the workers present and other road users. Work zones typically present unique hazards, such as sudden lane changes, construction vehicles entering and exiting the roadway, and workers moving about. Reduced speeds provide drivers with increased reaction time and greater control over their vehicle, helping to prevent accidents.

While turning on headlights can improve visibility, especially in low-light conditions, it is not a specific requirement unique to work zones in the same way that reducing speed is. Similarly, using hazard lights and sounding the horn frequently may not be appropriate or effective in all situations and could potentially lead to confusion or misinterpretation of a driver's intentions. Therefore, focusing on reducing speed is the most crucial action required when approaching and navigating through an active work zone.
