Minnesota Traffic Engineering Manual (TEM)

The Traffic Engineering Manual (TEM) is issued and updated by the Minnesota Department of Transportation (MnDOT) Office of Traffic, Safety, and Technology (OTST). The purpose of the TEM is to establish uniform guidelines and procedures, primarily for use by MnDOT personnel. Counties, cities, and local units of government will also find this manual useful when striving for uniformity in traffic engineering throughout the state of Minnesota. Uniform application of guidelines and procedures aids the road user in recognizing and understanding the various traffic control devices used throughout the United States
