Signs and markings are traffic control devices used to promote highway safety and efficiency by providing for the orderly movement of all road users on streets, highways, bikeways, and private roads open to public travel throughout North Carolina.
The intent of such traffic control devices is to notify road users of regulations and provide warning and guidance needed for the uniform and efficient operation of all elements of the traffic stream in a manner intended to minimize the occurrences of conflicts and inefficiencies.
To be effective, all signing and marking traffic control devices should meet five basic requirements:
- Fulfill a need
- Command Attention
- Convey a clear, simple meaning
- Command respect from road users
- Give adequate time for proper response
