All traffic-related controls on all Maine roads open to the public must follow the national "Manual on Uniform Traffic Control Devices" (MUTCD). This manual provides guidance for traffic signs, pavement markings, work zones, school areas, and much more.

MUTCD

• The Manual on Uniform Traffic Control Devices (MUTCD) serves as the national, state, and local standard for traffic control during all operations on public streets and highways in the United States.  These minimum standards apply to all public roads regardless of type, class, or agency having jurisdiction over them.  It's important that the driving public sees and reacts to similar traffic control devices whether there is a local or state road crew, a utility truck, a contractor's crew, or emergency vehicles, etc

The Maine Local Roads Center provides training, technical assistance, and information to those municipal and county personnel who are responsible for constructing, maintaining, and managing local roads and bridges in Maine. Administered by the Maine Department of Transportation, the Maine Local Roads Center is one of over 50 “technology transfer” centers established by the Local Technical Assistance Program (LTAP) of the Federal Highway Administration.

Working to Move Maine: MaineDOT's Family of Plans

MaineDOT’s Family of Plans is a set of multimodal and modal transportation planning documents that lay out the department’s vision for Maine’s transportation system, present recommendations for how to achieve the vision, and lay out the path to implementing them.  

The Bureau of Planning is MaineDOT’s primary point of contact for Maine’s Metropolitan Planning Organizations (MPOs), Regional Planning Organizations (RPOs), municipalities, other stakeholders, and members of the public for all modes of transportation. It is also home to MaineDOT’s Tribal Liaison. The Bureau of Planning carries out long-range planning efforts and helps develop MaineDOT policies. For municipal support, the MaineDOT Community Services Division and the Maine Local Roads Center are located in Planning.

The Public Transit Advisory Council is a voluntary board established in statute to advise the State Legislature and the Maine Department of Transportation on public transit services in the state. Council members are appointed by the MaineDOT Commissioner and represent a broad range of perspectives. The Council is administered by MaineDOT.
