How long can a Short Duration work zone last?

A Short Duration work zone is defined as a temporary work area that has a limited impact on road traffic and is typically in place for a brief period. The correct choice is that a Short Duration work zone can last less than 1 hour. This classification is primarily used for activities that do not require extensive preparations or setups and can be done quickly, thus minimizing disruption to traffic.

This type of work zone is often associated with tasks like maintenance or utility work that can be completed swiftly without the need for lengthy detours or significant traffic control measures. The goal of such work zones is to provide maintenance or construction work while ensuring a minimal interruption to vehicular and pedestrian traffic.

Longer durations, such as 1-3 days or more than 3 days, would typically fall into categories labeled as long-term work zones or short-term work zones, which have different traffic management strategies and implications for road users. Nighttime work lasting more than 1 hour could also lead to a different classification since it suggests a more extended and potentially more congestive impact on traffic flow.
