Objectives
• Develop an occupational profile that addresses the client’s driving
needs.
• Select specific evidence-based assessments and assessment methods
to assist in determining driving readiness.
• Using the information gathered from the occupational profile,
assessments, and goals determine the need to refer client’s to the
DRS.
• Gain knowledge in the laws and agencies in the state of Texas that
determine driving fitness to assist OT practitioners in establishing
treatment plans and goals.
About the speaker
• Introduced to clinical driving evaluations in 1987
• Attended my first ADED conference in 1989?
• Developed a pre-driving clinical screen and evaluation in 2010
• Passed CDRS exam August 2013
“So, what are you going to do about driving?”
Why should occupational therapist evaluate
fitness to drive?
Things to consider
•
•
•
•
There are 20 million drivers in the U.S. 70 and older.
Every year, more than 795,000 people in the United States have a stroke.
400,000 individuals estimated to have MS.
Approximately 60,000 Americans are diagnosed with Parkinson's disease
each year, and this number does not reflect the thousands of cases that go
undetected.
• One in four adults−approximately 61.5 million Americans−experiences
mental illness in a given year
• Approximately two million Americans have mild low vision which affects
driving and reading.
Why Should OT evaluate fitness to drive?
• Because driving is an instrumental activity of daily living within the
domain of occupational therapy practice.
• practitioners should be able to accurately determine who is a safe
driver, who is at risk for unsafe driving, and who needs further
evaluation by a driving rehabilitation specialist (DRS).

Occupational Therapy Roles
• Generalist: general knowledge and understanding of performance
and processing skills related to driving.
• Advanced Training: Further education to evaluate the integration of
sub-skills associated with driving and provide specific sub-skill training
• Specialized Training: Received specialized education, examination,
and/or certification.

Let’s Start with the
law!
Texas MAB
Texas Medical Advisory Board (MAB)
• The Texas Medical Advisory Board (MAB) for Driver Licensing was
established in 1970 to advise the Texas Department of Public Safety
(DPS) in the licensing of persons having medical limitations which
might adversely affect driving.
• Guidelines established using the following:
AMA Physician’s Guide for Determining Driver Limitation
Driver Fitness Medical Guidelines (NHTSA)
The American Association of Motor Vehicle Administrators
Texas Medical Advisory Board/DPS
• The ultimate goal is to allow all who can drive safely to do so and to
continue to reduce the number and severity of motor vehicle
accidents in Texas
