Traffic signs with black and white letters are primarily classified as which type?

Traffic signs with black and white letters are primarily classified as regulatory signs. These signs are designed to inform road users of specific laws and regulations that must be obeyed. For instance, they include speed limit signs, no parking signs, and stop signs, which communicate essential information related to vehicle operation and road use.

Regulatory signs are critical for maintaining safety and order on the road. Drivers are required to follow the instructions on these signs to avoid legal penalties and accidents. Understanding the function of regulatory signs is vital for all road users, as compliance is not optional—failure to adhere to these signs can result in fines or dangerous driving situations.

This classification is distinct from warning signs, which typically use bright colors to alert drivers of potential hazards, guide signs that provide directional information, and construction signs that announce upcoming road work or changes. Each type of sign serves a unique purpose in traffic management, but black and white signs are specifically indicative of regulatory messages.
