MnDOT publishes two documents on standard signs and standard markings designs referenced in the Minnesota Manual on Uniform Traffic Control Devices (MN MUTCD) and MnDOT Traffic Engineering Manual.

2020 MnDOT Standard Signs and Markings Summary

The 2020 MnDOT Standard Signs and Markings Summary (PDF) is a quick reference guide of commonly used standard codes, sizes and MnDOT stock numbers.  New in 2020, MnDOT upgraded the standard signs to align with the federal standard signs. The font changed to 2k and some sign codes, designs and sizes changed. Added a pavement marking section which includes installation and removal sizes of different types of pavement markings.
The Standard Sign and Marking Summary Update (XLS) spreadsheet is an ongoing list of changes that have been made to the 2020 MnDOT Standard Signs and Markings Summary since it was initially published. This spreadsheet and the summary are reviewed and updated quarterly.

2020 MnDOT Standard Signs and Markings Manual

The 2020 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 2020 manual is based off of 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 also has some updated sign designs. The designs in the 2012 book take precedence over the 2004 book.
