MnDOT Standard Signs and Markings Manual
The MnDOT Standard Signs and Markings Manual is a supplement to the FHWA Standard Highway Signs and Markings book. The MnDOT manual includes sign and marking designs for Minnesota specific signs as well as designs not found in the FHWA book. It also includes punching codes for signs mounted on MnDOT sign structures.
MnDOT’s manual is based off the two FHWA’s Standard Highway Signs and Markings book; 2004 Edition and the 2012 Supplement to the 2014 Edition. The 2012 Supplement has standard signs not included in the 2004 Edition and has some updated sign designs. The designs in the 2012 book take precedence over the 2004 book.
