What is meant by uniformity of traffic control devices?

Uniformity means treating similar situations in the same way. This simplifies the task of the driver because it aids in instant recognition and understanding.

 

Uniformity aids police, courts, and road users by giving everyone the same interpretation. It aids public highway officials through economy in manufacture, installation, maintenance, and administration.

 

The "Michigan Manual on Uniform Traffic Control Devices" is the publication that sets forth the basic principles which govern the design and use of traffic control devices. The Manual was prepared by a State Advisory Committee which included state, county, and municipal representation.

 

The standards in this Manual, with certain exceptions, apply to all streets and highways regardless of the governmental agency having jurisdiction.
