Chapter 5
The Driver Rehabilitation Specialist

After scoring Mr. Phillips’ performance on ADReS, you discuss the results with him. You assure him that he scored well on the cognitive tests, but that his performance on the visual and motor tasks signals the need for improvement.

You recommend that Mr. Phillips make an appointment to see his ophthalmologist, whom he has not seen in the past year. You also recommend that he begin exercising regularly by walking for 10-minute intervals, three times a day, and stretching gently afterwards. His son, who is present at the clinic visit, offers to walk and stretch with him several times a week. You ask Mr. Phillips to return to your office in one month.

When Mr. Phillips arrives for his follow-up appointment, he is wearing new glasses. His vision with the new glasses is 20/30 OU. You retest his motor skills, and he is now able to complete the Rapid Pace Walk in 8.0 seconds. His lower extremity strength has improved to 4+/5, but his range of motion on finger curl and neck rotation have not improved. With Mr. Phillips’ agreement, you refer him to a driver rehabilitation specialist for vehicle adaptive devices to help him improve his steering wheel grip and side and rear view.

Despite your interventions, your patient will sometimes continue to experience functional deficits that may impair his/her driving performance. In this case, a driver rehabilitation specialist (DRS) is an excellent resource. A DRS can perform a more in-depth functional assessment and evaluate your patient’s performance in the actual driving task. Based on the patient’s performance, the DRS may recommend that the patient continue driving with or without further restrictions or interventions, recommend adaptive techniques and devices to overcome functional deficits, or recommend that the patient retire from driving.

This chapter will provide you with information you should know before you refer your patient to a DRS.

What is a driver rehabilitation specialist?

A DRS is one who “plans, develops, coordinates, and implements driving services for individuals with disabilities.”1 DRSs are often, but not necessarily, occupational therapists who undergo additional training in driver rehabilitation. Aside from occupational therapy, DRSs also come from backgrounds such as physical therapy, kinesiotherapy, psychology, and driver education.

Many driver rehabilitation specialists receive certification from the Association for Driver Rehabilitation Specialists (ADED)* by fulfilling education and experience qualifications2 and passing a certification exam.3 Certified driver rehabilitation specialists (CDRS) renew their certification every three years by fulfilling a minimum amount of continuing education units. While many DRSs either hold certification or are in the process of obtaining the necessary education and experience, certification is not required to practice driver rehabilitation nor for ADED membership.

What do DRSs do?

A DRS evaluates the client’s driving skills and provides rehabilitation as needed to enable the client to resume or continue driving safely. Although driver rehabilitation programs may vary, most typically include the elements listed in Figure 5.1 in their evaluation.

Figure 5.1
Elements of DRS Evaluation4

Driver Evaluation

  • Clinical assessment, including review of driving history, driving needs, and license status; review of medical history and medications; visual/perceptual assessment; assessment of range of motion, motor strength, coordination, sensation, and reaction time; and cognitive assessment.
  • Functional (on-road) assessment, including assessment of vehicle ingress/egress, mobility aid management (eg, ability to transport a wheelchair or scooter), vehicle preparation, vehicle control, adherence to traffic rules and regulations, environmental awareness and interpretation, and consistent use of compensatory strategies for visual, cognitive, physical, and behavioral impairments.
  • Communication of assessment results and recommendations to the client:
    • Return to driving, with or without adaptive driving equipment.
    • Limit driving with restrictions placedon either the geographic areas or conditions in which the client drives.
    • Attend a remedial driving course to establish/maintain defensive driving skills.
    • Receive adaptive driving instructionor driver retraining using a vehicle matched to the client’s individual needs.
    • Cease driving. This is advised when a client does not demonstrate the necessary skills to resume driving, and potential for improvement with retraining is poor. In these cases, alternative transportation options should be reviewed with the client.
    • Receive re-evaluation. This option is indicated if a client’s function is expected to improve, or if a client demonstrates adequate skills to drive at present but has a progressive disorder that may cause future decline.

Passenger Vehicle Evaluation

  • Assessment of vehicle, vehicle modifications, and equipment needed for the client’s safe transport as a passenger.
  • Consideration of the needs of the patient’s family (for example, certain lifts or tie-down systems may be preferable due to an assisting family member’s physical limitations).

Treatment and Intervention

  • Adaptive driving instruction or driver retraining, with or without vehicle modifications.
  • Coordination of vehicle modifications—
    • Vehicle consultation: The DRS serves as a consultant to clients who are purchasing a new vehicle to ensure that the vehicle will accommodate the necessary adaptive equipment.
    • Vehicle modification recommendations: The DRS provides written recommendations for all vehicle/equipment needs to the client, third party payer, and vehicle/equipment dealer.
    • Vehicle inspection: The DRS assists the client and adaptive equipment dealer in a final fitting to ensure optimal functioning of the recommended vehicle/equipment.

An initial driver evaluation can last one to four hours, depending on the client’s presenting disabilities and driving needs. Following the clinical assessment, clients undergo an on-road assessment if they meet the minimum state standards for health and vision, and the client holds a valid driver’s license or permit. The on-road assessment is performed in a driver rehabilitation vehicle equipped with dual brakes, rear-view mirror and eye-check mirror for the DRS, and any necessary adaptive equipment.

Please note that clients who perform poorly on the clinical assessment may still undergo on-road assessment. In these cases, the DRS may recommend on-road assessment for one of two reasons: (1) Clients who perform poorly on individual components of the clinical assessment may still demonstrate safe driving due to overlearning the driving task; and (2) clients and family members may need concrete evidence of unsafe driving, which can only be documented through observation of behind-the-wheel performance.

Who can DRSs help?

Driver assessment and rehabilitation are appropriate for a broad spectrum of physical and cognitive disabilities. DRSs work with clients who have dementia, stroke, arthritis, low vision, learning disabilities, limb amputations, neuromuscular disorders, spinal cord injuries, mental health problems, cardiovascular diseases, and other causes of functional deficits.

Driver rehabilitation can be as straightforward as providing extended gear shift levers, padded steering wheels, and extra mirrors to patients with arthritis, and training them in their use. It can also be as complex as working with a client with dementia and his/her caregivers to determine the client’s driving needs, plan driving routes for the client, supervise practice drives, and provide close and extended follow-up.

What is the cost of driver assessment and rehabilitation?

While the cost of driver assessment and rehabilitation varies between programs and according to the extent of services provided, it is typically $200 to $400+ for a full assessment and $100 an hour for rehabilitation. If adaptive equipment is required, it can cost approximately $70 for a spinner knob, $300 for a left foot accelerator, $700 for hand controls, and thousands of dollars for reduced-effort steering systems, wheelchair lifts, and raised roofs and dropped floors on vans.

Two programs consistently pay for all driver assessment, driver rehabilitation, and vehicle modifications; namely, each state’s Workers Compensation and Vocational Rehabilitation programs. Unfortunately, many older drivers do not qualify for either program, and insurance coverage from Medicare, Medicaid, and private insurance companies is variable. In general, Medicare does not reimburse for driving services, and private insurance companies—basing their coverage on Medicare’s covered services—act accordingly. However, some driver rehabilitation programs have successfully pursued insurance reimbursement from Medicare and other providers. (Note that while Medicare may provide partial or full reimbursement for driver assessment and rehabilitation, it does not cover the cost of adaptive equipment.) At present, the American Occupational Therapy Association (AOTA) is actively lobbying for consistent Medicare coverage of OT-performed driver assessment and rehabilitation, with the assertions that these services fall under the scope of OT practice and that driving is an instrumental activity of daily living (IADL).

Because rates and extent of insurance reimbursement vary between driver rehabilitation programs, you will need to ask each individual driver rehabilitation program about its rates, insurance coverage, and payment procedures (eg, patient pays up-front and is reimbursed when insurance payments are received, or payment is collected directly from the insurance provider).

Where can I find a DRS?

Driver rehabilitation programs and DRSs in private practice are often affiliated with hospitals, rehabilitation centers, driving schools,and state driver licensing agencies. DRSs can sometimes be found through Area Agencies on Aging, universities, and area Departments of Education as well.

To locate a DRS in your area, you may wish to start by calling the occupational therapy departments in your local hospitals and rehabilitation centers. The Association for Driver Rehabilitation Specialists’ (ADED) online directory is another good place to start. The directory, which can be found by clicking on the ‘Directory’ button at www.driver-ed.org or www.ADED.net, lists all 637 ADED members as of January 2003. You can search the directory by state, country, type of facility, services offered, and professional background of the DRS, as well as by name of the DRS or name of the driver rehabilitation program. Please note that not all ADED members provide assessment and rehabilitation services; some are involved solely in vehicle modification, as indicated in their ‘program and services’ field.

When selecting a DRS or driver rehabilitation program, there are several things you should ask:

Making the referral

Prior to making the referral, let your patient know why he/she is being referred, what the assessment and rehabilitation will accomplish, what these will consist of, and how much he/she can expect to pay out of pocket for these services.


For example, you could tell Mr. Phillips

“Mr. Phillips, I’m pleased that you can see better with your new glasses, and that your physical fitness has improved with your walking and stretching. I’d like you to keep up the good work. However, I’m worried about your poor hand grip and I’m concerned that you can’t see around you well enough to drive safely. I’d like to send you to someone who can help you with these things.”

“This person, who’s called a driver rehabilitation specialist, will ask you some questions about your medical history and test your vision, strength, range of motion, and thinking skills—similar to what we did the last time you were here. He/she will also take you out on the road and watch you while you drive. Afterwards, he/she might recommend some accessories for your car, such as extra mirrors, and show you how to use them.”

“The cost of this assessment is $400. Training costs $100 an hour, and the car accessories may cost around $100 to $200. However, your insurance will pay for 80% of the assessment and training. This means that you’ll pay $80 for the assessment, and—if you need them—$20 an hour for training and $100 to $200 for accessories.††† I know this sounds like a lot of money, but I think this is important for your safety. If you were to ever get into a car crash, your medical bills could end up costing you more money, and you might suffer a great deal of pain and disability. I’d like to prevent that from happening.”



When writing the prescription, list a specific reason for assessment and rehabilitation. Assessment because the patient is “elderly,” “debilitated,” or “frail” does not provide much guidance to the DRS and can complicate insurance reimbursement. On the other hand, “OT driver evaluation for poor finger flexion and neck rotation secondary to arthritis,” “DRS evaluation for hemianopia secondary to stroke,” and “CDRS evaluation for cognitive deficits secondary to Alzheimer’s Disease” provide more guidance for the DRS and are more likely to be reimbursed by insurance.

Remind your patient to follow up with you after he/she undergoes evaluation. If your patient is safe to drive (with or without restrictions, adaptive devices, and/or rehabilitation), reinforce any recommendations made by the DRS. When applicable, family and caregivers should be informed of these recommendations. Also remember to counsel your patient on the Tips for Successful Aging and Safe Driving Tips, and encourage your patient to start planning alternative forms of transportation in case they ever become necessary. If your patient is not safe to drive, then you will need to counsel your patient on driving cessation. This is discussed in the following chapter.

What if driver assessment is not an option?

Unfortunately, driver assessment and rehabilitation may not always be feasible options for your patients. In some areas, DRSs simply are not available. Even if a DRS is available, your patient may refuse further assessment or be unable to afford it.

If driver assessment is not an option, you have several choices:

Before referring patients to driving schools for driver assessment and rehabilitation, physicians are urged to ascertain that the staff has training and experience in driver rehabilitation. A background in driver education alone may be insufficient for appropriate assessment of medically impaired drivers and correct interpretation of the assessment.

†† Please note that DRS counseling does not preclude the need for physician follow-up. Many times, the patient may be too distressed at the time of DRS counseling to absorb information. Physician counseling is crucial for reinforcement of this information, and it demonstrates to the patient the physician’s involvement and support.
