What type of sign is generally black and white?

The correct choice is regulatory sign, as these signs are typically designed in a black and white color scheme to convey important laws and regulations that drivers must follow. The black and white coloring is intended to catch the driver's attention and communicate serious commands clearly, such as speed limits, no parking zones, and other rules of the road. These signs are crucial for maintaining order and safety on the streets by informing drivers of their responsibilities.

In contrast, warning signs often use bright colors like yellow to alert drivers to potential hazards or changes in road conditions. Information signs generally incorporate various colors and symbols to provide guidance or details to motorists, such as directions or points of interest. Construction signs are also brightly colored, often using orange, to signal upcoming work zones and to ensure that drivers are cautious in areas where there may be changes to traffic patterns.
