What is the MUTCD?
The MUTCD stands for the Manual on Uniform Traffic Control Devices. It is published by the U.S. Department of Transportation (DOT) Federal Highway Administration. All state level DOTs are required to adhere to the MUTCD. The MUTCD states that “all workers exposed to the risks of moving roadway traffic or construction equipment should wear high-visibility safety apparel meeting the requirements of ANSI/ISEA 107-2004 standard performance for Class 1, 2 or 3 risk exposure.” The manual also spells out specific class requirements for flagging crews (must wear Class 2 during the day and should wear Class 3 at night).
