Excerpted from the Department of Transportation Regulations on "Transportation Services for Individuals with Disabilities" at 49 CFR Part 37
(a) Application. This section applies to all purchases or leases of vehicles by private entities which are not primarily engaged in the business of transporting people, in which a solicitation for the vehicle is made after August 25, 1990.
(b) Fixed Route System. Vehicle Capacity Over 16. If the entity operates a fixed route system and purchases or leases a vehicle with a seating capacity of over 16 passengers (including the driver) for use on the system, it shall ensure that the vehicle is readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs.
(c) Fixed Route System. Vehicle Capacity of 16 or Fewer. If the entity operates a fixed route system and purchases or leases a vehicle with a seating capacity of 16 or fewer passengers (including the driver) for use on the system, it shall ensure that the vehicle is readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs, unless the system, when viewed in its entirety, meets the standard for equivalent service of §37.105 of this part.
(d) Demand Responsive System, Vehicle Capacity Over 16. If the entity operates a demand responsive system, and purchases or leases a vehicle with a seating capacity of over 16 passengers (including the driver) for use on the system, it shall ensure that the vehicle is readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs, unless the system, when viewed in its entirety, meets the standard for equivalent service of §37.105 of this part.
(e) Demand Responsive System, Vehicle Capacity of 16 or Fewer. Entities providing demand responsive transportation covered under this section are not specifically required to ensure that new vehicles with seating capacity of 16 or fewer are accessible to individuals with wheelchairs. These entities are required to ensure that their systems, when viewed in their entirety, meet the equivalent service requirements of §§37.171 and 37.105, regardless of whether or not the entities purchase a new vehicle.
For purposes of §§37.101 and 37.103 of this part, a fixed route system or demand responsive system, when viewed in its entirety, shall be deemed to provide equivalent service if the service available to individuals with disabilities, including individuals who use wheelchairs, is provided in the most integrated setting appropriate to the needs of the individual and is equivalent to the service provided other individuals with respect to the following service characteristics:
(a) (1) Schedules/headways (if the system is fixed route);
(2) Response time (if the system is demand responsive);
(b) Fares;
(c) Geographic area of service;
(d) Hours and days of service;
(e) Availability of information;
(f) Reservations capability (if the system is demand responsive);
(g) Any constraints on capacity or service availability;
(h) Restrictions priorities based on trip purpose (if the system is demand responsive).
A private entity not primarily engaged in the business of transporting people which operates a demand responsive system shall ensure that its system, when viewed in its entirety, provides equivalent service to individuals with disabilities, including individuals who use wheelchairs, as it does to individuals without disabilities. The standards of §37.105 shall be used to determine if the entity is providing equivalent service.
