Final answer:
A black and white traffic sign typically provides regulatory information and law enforcement details, guiding drivers on traffic laws to follow for safe driving.
Step-by-step explanation:
A black and white traffic sign typically conveys regulatory information and law enforcement. These signs indicate traffic laws and regulations which drivers must follow, such as speed limits, no turn on red, stop, yield, and pedestrian crossing areas.
Black and white signs do not typically warn about potential hazards, provide directions and guidance, or give information about services and facilities. Instead, yellow signs are used for warnings, green for directions, and blue for services and facilities.
Understanding these sign colors and their meanings contributes to safer driving and helps in avoiding traffic violations.
