Minn. Stat. § 171.163

An agency, court, or public official in Minnesota shall not mask, defer imposition of judgment for, or allow an individual to enter into a diversion program that would prevent a conviction for a violation of a state or local traffic control law, except a parking violation, from appearing on the driving record of a holder of a commercial driver's license, when the violation is committed in any type of motor vehicle, or on the driving record of an individual who committed the violation in a commercial motor vehicle.
