This bill proposes regulations on the use of the reversible high-occupancy vehicle (HOV) lane on Interstate Highway 394 in Minnesota. It mandates that the lane must generally be maintained in the eastbound direction. However, the Minnesota Commissioner of Transportation may temporarily switch the lane to westbound use under specific conditions:

1. A major planned event is occurring in the metropolitan area that affects traffic patterns.
   
2. The public is notified at least 48 hours in advance about the change in the lane's hours and direction.
   
3. The lane is restored to its eastbound direction as soon as practicable after the event.
   

The bill defines a "major event" as arts and cultural events, sporting events, entertainment events, or other significant attractions that impact traffic flow.
