What kind of signs are considered regulatory in work zone settings?

Regulatory signs in work zone settings are specifically designed to communicate laws, rules, and regulations that must be followed by road users. These signs inform drivers about speed limits, detours, lane closures, and other critical information necessary for maintaining safety and efficient traffic flow.

In contrast, signs that provide directions are primarily orientational and help guide drivers along the route or to a destination but do not impose a legal obligation. Signs intended for advertising serve a completely different purpose and do not convey regulatory information related to traffic control. Therefore, regulatory signs are essential for emphasizing compliance with the traffic laws specific to the work zone, ensuring both driver safety and adherence to necessary regulations.
