Which sign type indicates traffic regulations?

Regulatory signs are specifically designed to inform drivers of the laws and regulations that must be followed on the road. These signs provide essential information on things like speed limits, right-of-way rules, and other legal requirements motorists must adhere to in order to maintain safety and order on the streets. They often use red and white colors, such as stop signs and yield signs, to convey their messages clearly.

Guide signs, primarily used for navigation, offer information about directions and distances, while warning signs alert drivers to potential hazards or changes in road conditions ahead but do not stipulate regulations. Work zone signs indicate temporary changes to road use due to construction or road work but fall outside the scope of general traffic regulations. Each type of sign serves a distinct purpose, but for conveying mandatory traffic rules, regulatory signs are the clear choice.
