Minn. Stat. § 219.24: ADDITIONAL SAFEGUARD.

If the commissioner of transportation finds in an investigation instituted upon the commissioner's own motion or upon complaint and after notice and hearing, that conditions at a grade crossing require additional safeguards to protect life and property, such as crossing gates or other suitable devices, the commissioner shall specify the nature of the devices required and may order the railway company operating the railroad at the crossing to install them.
