The introduction of new technology continues to broaden opportunities for people with disabilities to drive vehicles with adaptive devices. Taking advantage of these opportunities, however, can be time consuming and, sometimes, frustrating. The information in this brochure is based on the experience of driver rehabilitation specialists and other professionals who work with individuals who require adaptive devices for their motor vehicles. It is centered around a proven process —evaluating your needs, selecting the right vehicle, choosing a qualified dealer to modify your vehicle, being trained, maintaining your vehicle — that can help you avoid costly mistakes when purchasing and modifying a vehicle with adaptive equipment. Also included is general information on cost savings, licensing requirements, and organizations to contact for help. Although the brochure focuses on drivers of modified vehicles, each section contains important information for people who drive passengers with disabilities.
