Many communities offer some sort of transportation for persons with disabilities such as an accessible city bus system, paratransit buses, accessible taxis, or private service companies. School systems may be required to provide transportation to events, field trips, and other activities. Parents should discuss their needs with school district personnel. Independent living resource centers, developmental disability organizations, and other regional agencies sometimes have transportation options as well. Under the ADA, community parks and recreation classes and programs must make reasonable accommodations for persons with disabilities. Some adapted sports programs offer transportation services.
