Line 11:
The MUTCD was first released in 1935, and set standards for both road signs and pavement markings. Since that time, eight more editions of the manual have been published with numerous minor updates occurring between, each taking into consideration changes in usage and size of the nation's system of roads as well as improvements in technology.
 
In 1966, Congress passed the Highway Safety Act, P.L. 89-564, 72 Stat. 885 (1966), which is now codified at 23 U.S.C. § 401 ''et seq.'' It required all states to create a highway safety program by [[December 31]], [[1968]], and to adhere to uniform standards promulgated by the U.S. Department of Transportation as a condition of receiving federal highway-aid funds.<ref>Edward C. Fisher, Vehicle Traffic Law (Evanston, IL: Traffic Institute, Northwestern University, 1961) (1967 supp.): 11.</ref> The penalty for noncompliance was a 10% reduction in funding. In turn, taking advantage of broad rulemaking powers granted in 23 U.S.C. § 402, the Department simply adopted the entire MUTCD by reference at 23 CFR § 655.603. Thus, what was formerly a quasi-official project became an official one. States are allowed to supplement the MUTCD but must remain in "substantial conformance" with the national MUTCD and adopt changes within two years after they are adopted by FHWA.
 
The [[National Committee on Uniform Traffic Control Devices]] (NCUTCD) advises FHWA on additions, revisions, or changes to the MUTCD.
