49 CFR Parts 37 & 38 - Department of Transportation (DOT) ADA Regulations

The definition of "wheelchair'' includes a wide variety of mobility devices. This inclusiveness is consistent with the legislative history of the ADA (See S. Rept. 101-116 at 48). While some mobility devices may not look like many persons' traditional idea of a wheel chair, three and four wheeled devices, of many varied designs, are used by individuals with disabilities and must be transported. The definition of "common wheelchair,'' developed by the Access Board, is intended to help transit providers determine which wheelchairs they have to carry. The definition involves an "envelope'' relating to the Access Board requirements for vehicle lifts.
