The bill mandates the transportation commissioner to adopt revisions to traffic engineering studies and investigations specifically for setting speed limits. By July 1, 2024, the commissioner is required to implement the standards and guidance from the 11th Edition of the Manual on Uniform Traffic Control Devices for Streets and Highways, as established by the United States Department of Transportation. This implementation will override the existing requirements of the Minnesota Manual on Uniform Traffic Control Devices.

Additionally, the bill includes a provision that this section will expire once the relevant revisions to the Minnesota Manual on Uniform Traffic Control Devices are adopted. The commissioner is tasked with notifying the revisor of statutes about the expiration, either electronically or in writing. The effective date of this section is set for the day following its final enactment.
