Carpool Policies and Procedures

The Portland Bureau of Transportation administers the on-street carpool parking program in order to improve access to the Central City and reduce the number of single-occupancy vehicles throughout the metropolitan area. Eligible carpoolers may purchase monthly permits to park within the designated carpool permit zones.
