Mandatory fine elimination for school bus stop-signal arm violations

This bill removes the $500 minimum fine for drivers who fail to stop for school buses when the stop-signal arm is extended. It amends Minnesota Statutes section 169.444 to eliminate the mandatory $500 penalty, allowing courts to impose fines without a minimum amount. The law directly affects drivers who violate basic school bus stop-signal requirements. The change applies only to the standard violation penalty (not the more severe gross misdemeanor penalties for passing a bus).
