Obtain Training on the Use of New Equipment
Both new and experienced drivers need training on how to safely use new adaptive equipment. Your equipment dealer and evaluator should provide information and off-road instruction. You will also need to practice driving under the instruction of a qualified driving instructor until you both feel comfortable with your skills. Bring a family member or other significant person who drives to all your training sessions. It's important to have someone else who can drive your vehicle in case of an emergency.
Some state vocational rehabilitation departments pay for driver training under specified circumstances. At a minimum, their staff can help you locate a qualified instructor. If your evaluator does not provide on-the-road instruction, ask him or her for a recommendation. You can also inquire at your local motor vehicle administration office.
MaintainYour Vehicle
Regular maintenance is important for keeping your vehicle and adaptive equipment safe and reliable. It may also be mandatory for compliance with the terms of your warranty. Some warranties specify a time period during which adaptive equipment must be inspected. These "check ups" for equipment may differ from those for your vehicle. Make sure you or your modifier submits all warranty cards for all equipment to ensure coverage and so manufacturers can contact you in case of a recall.
