Before attempting to drive with ours or any other driving aid it is essential that you are evaluated by a Certified Driver Rehabilitation Specialist (CDRS). Referrals to a driver rehabilitation program or CDRS for those with disabilities can be made by physicians, specialists, eye doctors, occupational therapists, driving schools, gerontologists, parents or spouses, the individuals themselves, and other sources. A “disability” is classified as a condition impeding completion of daily tasks using traditional methods. Driver training for a person with a disability is frequently provided after a thorough driver evaluation, and should ideally be conducted by a CDRS or DRS. A driver evaluation generally consists of a clinical assessment and a behind-the-wheel assessment. The evaluation process generally includes tests of physical function, vision, perception, attention, motor function, and reaction time, in addition to actual driving performance tests. Based on the evaluation results, the CDRS or DRS will determine if any adaptive driving equipment is needed, whether the individual has the ability to drive independently or at all, and whether they require driver rehabilitation or training. Assessment can average three to eight hours, and training is customized to the unique needs of each individual. Some of the recommended vehicle adaptations could include lifts; ramps; custom seating; steering devices, such as spinner knobs and other specially-designed handles for the steering wheel; hand controls; foot pedal extensions; special mirrors; extenders and extensions for dash controls; and other adaptive tools.
