Which federal agency provides guidelines for MOT?

The Federal Highway Administration (FHWA) is the agency responsible for providing guidelines and standards related to the safety and management of traffic in maintenance operations. The FHWA plays a crucial role in ensuring that motor vehicle travel remains safe and efficient, especially during construction and maintenance activities. Their comprehensive guidelines for Maintenance of Traffic (MOT) help state and local agencies develop plans that minimize disruptions and enhance safety for both workers and the public. The FHWA's focus on traffic control and management based on established best practices makes it the primary authority in this area.

While the other agencies mentioned have important roles in transportation safety and environmental concerns, they do not specifically focus on traffic maintenance and management practices in the same way that the FHWA does. For example, the Environmental Protection Agency (EPA) deals with environmental regulations, the National Transportation Safety Board (NTSB) investigates transportation accidents, and the Federal Motor Carrier Safety Administration (FMCSA) focuses on regulations affecting commercial motor vehicles. Therefore, the FHWA is clearly the expert agency in providing the necessary guidelines for Maintenance of Traffic.
