History of the MUTCD

The 1900’s  brought economic affluence and the automobile to America, and soon families were venturing further from home on weekend outings.  Quite often, people would become lost or confused by vague or absent directional signs. Also, it generated a need for wider roads and driving etiquette.   Groups organized to post signs for major roadways often overlapping with the efforts of other groups.  Some heavily traveled routes could boast of almost a dozen different sign markings.  Obviously, this led to confusion and demonstrated the need for a standardized sign and road marking guide which developed into the MUTCD.  For a more detailed article about the MUTCD click here.
