WTA’s paratransit service provides curb-to-curb (and if needed, door-to-door) transportation to riders whose disability prevents them from riding our fixed route bus system.
You may use paratransit for any trip purpose, other than a medical emergency. Paratransit riders use the bus to get to work or school, to visit friends and family, to go shopping, or to church, to see movies, enjoy parks and trails, keep medical or dental appointments, and many other trip purposes. By law WTA may not give one trip purpose priority over another.
Everyone who rides paratransit must qualify and be approved before riding.
