Neuropsychology
and Driving
Role of Executive Functioning in Driving
– What is executive functioning?
The ability to formulate a plan and
execute the plan
Planning, decision making and response
selection
Problem solving, planning and judgment
Volition, planning, purpose of action-
effective performance
78
Executive Functioning
Volition = what one needs or wants, initiation, self
awareness, motivation
Planning = identify and organize steps
Purpose of Action = put plan into activity, manage
sequences in orderly manner
Effective Performance = monitor, self-correct and
regulate intensity
Wheatley and Davis 2005
79
Neuropsychology and Driving
“The same cognitive skill they require to be able to
accurately assess their own difficulties is also at the
root of their other dysexecutive problems”
Burgess, et.al. 1998 p555;
Wheatley and Davis 2005
80
Neuropsychology and Driving
Performance on tasks of executive functioning is
predictive of on road driving ability and
accident risk, strong correlations researched
81
Neuropsychology and Driving
Executive Functions = selective and divided attention,
tested best with UFOV (Useful Field of Vision/View)
UFOV (Useful Field of Vision/View) - has strong
predictive validity for crashes and driving evaluations
and correlated strongly with Trails B*
Other test options: CLQT, Stroop*, Rey Osterrieth-
Complex Figure Test, Matrix Reasoning, Letter
Number Sequencing, Colored Trails Test, Tower of
London, Wisconsin Card Sorting Test, Rey Complex
Figure, MVPT, Clock Drawing Test, Benton Visual
Retention Test, Block Design Test, ACLS
82
Michon Hierarchy of Driving
1. Operational - Basic Vehicle Control = steer, brake,
accelerator
2. Tactical - In Traffic = speed, wipers, lights, lane
placement
3. Strategic - Hazards = route choice, strategies
83
Executive Function and Deficits
Can be masked in structured assessments.
Fatigue, anxiety and distractions affect
executive function.
Speed of responses is critical.
Last to develop and last to return after injury.
Self awareness precedes initiation of strategy
or compensation.
84
Role of Insight of Deficit in Driving
Self regulation, self reflection and self awareness are
executive functions.
Self awareness is key to decide if one will be able to
learn and utilize compensatory strategies.
Decreased self awareness is important in predicting risk
for accidents to increase.
If intact, less likely to put themselves and others in
harm; if unaware of deficit then no reason to change it.
85
Neuropsychology and Driving
“Overestimate is common across
tasks/abilities, but driving encourages poor
insight because it is a high value task,
supporting: roles, independence, selfesteem, quality of life, and mood.”
Davis and Stern; Katz et al. 1990
86
Neuropsychology and Driving
“Results from research have revealed that most
individuals fail to recognize their decline in
driving competence and adjust to lower levels
of (performance naturally) such as visual acuity,
reaction time and cognition.”
Hunt, Morris, Edwards & Wilson 1993
Kartje 05
87
Decreased Self Awareness / Insight
Equals:
Decreased compliance with restrictions
Decreased Motivation
Decreased Decision Making
Increased Resistance to Treatment
Increased Risk Taking
Clients struggle with understanding how
tests relate to skills required to drive.

Medications as Predictors
of Driving Performance
Medications as Predictors of
Driving Performance
An increase in age leads to an increase in medical
conditions/disabilities which leads to an increase in
medications and decrease in memory (higher risk also
for Alzheimer’s Disease and Depression) which can
lead to impaired driving performance
“Older clients’ driving skills may deteriorate as a
result of medications, not a loss of inherent skills.”
Kartje 2005 and OT Practice 3/5/07
91
Medications as Predictors of
Driving Performance
Three or more drugs increases the risk of functional
decline in elderly by 60%
Decrease in functional ability secondary to increase in
polypharmacy (2-10 meds) = increases risk of MVA
PharMetrics Database Analysis reported that 64% of
drivers 50+ with a MVA was on a PDI within 60 days
OT Practice 3/5/07
92
Medications as Predictors of
Driving Performance
Potentially Driving Impaired (PDI) prescription
medications effect CNS, blood sugar level, blood
pressure and vision
Side effects of PDI: sedation, blurred vision,
dizziness, fainting and loss of coordination
Most common conditions are for HTN, Arthritis,
Heart disease, Cancer, Diabetes and Sinusitis
93
Medications as Predictors of
Driving Performance
Prescriptions and/or over the counter drugs can
create accessory functional problems such as motor
performance, vision, attention and information
processing and undermine driving performance.
Older drivers may be less aware of their surroundings
and less able to react in inappropriate and timely
manner to a dangerous situation on the road.
Pellerito 2006 p 198 and Stav 2004 p 21
94
Medications as Predictors of
Driving Performance

Tool for those who need to educate and
counsel older clients about medications
and associated driving risks
OT Practice 3/5/07

2 Classen Studies’ Findings
1. Pharmacological intervention is cornerstone of
CVA management and prevention:
– increases in polypharmacy.
– increases associations between drugs.
– increases adverse drug reactions.
– increases nonadherence to regimes.
– increases in IPD with multiple meds.
– increases drug drug interactions with more
than 3 meds.
96
2 Classen Studies’ Findings
2. Correlation between number of comorbidities and
number of medications.
3. Correlation between number of comorbidities and
number of IPDs (Inappropriate Prescribed Drugs).
4. The Beers Criteria identified 28 medications
potentially harmful to older adults.
5. Polypharmacy associated with increased risk of
potential drug-drug interactions (PDDIs).
6. Increase in number of meds and increase in age leads
to polypharmacy.
97
2 Classen Studies’ Findings
7. Increase in age and gender (being male) = decrease
in cognition.
8. Association between number of medications and
variables such as age, gender and total chronic
illnesses.
9. Increase age/increase number of
medications/increase in chronic illness= increase
morbidity, decrease cognition, decrease IADLs,
decrease health, decrease QOL, decrease in
functional status.
98
Potential Effects of Medications
Slower reaction time
Difficulty visually tracking objects
Alteration of depth perception
Diminished coordination while steering the
vehicle and accessing the braking system
Lack of attention
Confusion
Drowsiness
99
Potential Effects of Medications continued
Lack of awareness of surroundings
Decreased accuracy of movements
Decreased ability to perceive hazards
and identify risks

102
Driving Simulators
Best Practices and Appropriate Role
Until more research is conducted,
driving simulation should not replace
an on-the-road driving evaluation.
Gold standard is to test the client
behind the wheel so how and why are
simulators utilized?
104
Driving Simulators
Road tests are considered costly to
administer, dangerous, sometimes
unavailable and can be stressful and
impractical for routine testing of older
persons where as simulators allow
ability to repeatedly practice high-risk
skills safely and cost-effectively.
AJOT 2003 & Pellerito 2006
105
Driving Simulators
Helpful for clients to practice driving and see their
abilities and limitations. Assist with
insight/awareness with driving and other IADLs.
Increase willingness to follow
suggestions/recommendations.
Help identify drivers that are at risk for traffic
violations and accidents.
Assess challenging stimuli (inclement weather,
animate and inanimate obstacles, night driving).
106
Driving Simulators
Help connect abstract interventions with a personal
significant goal (such as strengthening, ROM or
cognition).
Allow practice of adapted driving aids in low risk
virtual environment before getting on the road.
Allow remediation and training of driving skills in a
controlled environment.
Help predict failure of on the road evaluation and
elevated crash risk
Help decide the optimal time to test on the road
(Watch Out for Simulator Sickness)
107
AJOT 2003 Findings
Visual attention skill declined with age was consistent
with the literature and validated the driving simulator
as an effective screening tool for older adult drivers.
Visual attention skill as the most important outcome
measure of traffic violations and automobile crashes.
Visual attention/speed of reaction times skill slowed
down during the second half across a time of 45
minutes simulated driving test.
108
AJOT 2003 Findings - continued
STISIM was validated as an off-road
screening tool for older adult drivers in
respect to their visual attention skill.
Suggests working memory or performing 2
tasks simultaneously may be tested with a
similar approach (selective attention and
divided attention mentioned too)
Suggests driving simulators are economical
and efficient clinical tools to measure skills
for driving
109
AJOT 2003 Findings - continued
PC-based Driving simulators were able to identify
unsafe older drivers at risk of traffic violations if
appropriate simulated driving tasks were used such as
working memory and use of indicator. They were able
to generate complex traffic scenarios comparable to
the on-road environment and conditions.
Confirms that a low-cost driving simulator can be used
by OTs as an off-road screening tool to identify older
drivers at risk of traffic violations.
Simulator technology can be employed for training
incompetent drivers too.
110
AJOT 2003 Findings - continued
Confirmed that cognitive skills such as working
memory, ability to make rapid decisions, judgment
under time pressure and confidence in driving at high
speed, were associated with the crash event.
Assess various levels of visual attention skill.
Could explain/reflect over 67% of on-road driving
behaviors and functions.
Confirmed that driving skills generally decline with age
(well-timed reaction and dexterous motor coordination
may deteriorate with physiological aging).
111
AJOT 2003 Findings - continued
Should target working memory and correct use of
indicator when assessing older adults for safe driving.
Use of indicator-Drive around “road work” obstacles
blocking the road and return to the inner lane as soon
as possible.
Working memory- remember 5 street names and 5
maneuvers marked on a route on a road map to a
fictitious park in 5 minutes and recall them after 10
minutes’ simulated driving.
Used the STISIM Driving Simulator for the study.
112
Doron Precision System’s Simulator
Strong validity in predicting road
performance with adults with CVAs and
adolescents with disabilities.

On-Road Evaluation
Determine Route by the Client’s Goal
Standard route vs. specialty routes
Standard- 2-3 hour route in all areas such
as rural, residential, commercial and
highway (50 minutes minimum on road)
Specialty- preplanned routes with
directions; i.e., house to the grocery
132
On-Road Evaluation – Common
Practices and Test Procedures
Common practices and test procedures increase the
reliability of outcomes, if followed.
Follow a standard, predetermined, clear documented
route.
Score predetermined aspects of behavior at
predetermined points along the route.
Include directions to the driver that are documented
clearly in the same form each test.
133
Common Practices and Test
Procedures - continued
Assessment criteria are operationally
defined and documented in specific terms
Follow a closely defined scoring procedure
Entails extensive training of testers
Pellerito 2006 p 264
134
Typical On Road Evaluation
Components
Basic Operations- in vehicle
Basic Maneuvers- in empty parking lot
Minimal Traffic- rural roads
Moderate/Heavy Traffic
Speed Control
Defensive Driving
Navigation
135
Key Factors of Assessment
Must have license with them.
Explain AE in vehicle.
“Follow the rules of the road.”
Are they comfortable with the vehicle?
Look for a pattern of errors- more than 3 or a
general pattern of errors, severity of error.
Can they fix the error; do they do better with
training; response to cues?
136
Key Factors of Assessment - continued
Determine bad habits vs. driving errors
Look for automatic responses to basic maneuvers
Tell them how they are doing throughout
Tell them what you would like improved, explain
errors immediately
Assumptions: reaction time will be slower in car
than in the clinic. You should see best
performance since it is a testing situation.
137
On-Road Evaluation Recommendations
Resume independent driving
Resume driving with AE
Resume driving with restrictions
Begin driver rehab training
No driving due to high risk for accidents
( only based on today’s performance)
(has to be able to be enforced)
138
Research –
AJOT July/August 2006 p 428-434
Concluded that most programs do not use
standardized on the road evaluations
Standardized Options: Miller Road Test,
Performance-Based Driving Evaluation,
Washington University Road Test and
DriveABLE Road Test
139
Research –
AJOT May/June 2004
Suggests that the evaluation have a
portion of self navigational
instruction vs. all directed navigation.
“Self-navigation challenges the driver
in a way that replicates real world
driving”
“Actively engaged in multiple tasks,
higher degree of cognitive and visual
ability”
140
Research - ADED 2007
Dementia clients recommended to have
revaluation every 6 months per best
practices of clinical standards.
Clinic test and on the road test need to
be close in time.
Frequency of re-evaluations (change in
condition, failures on the road).
141
Research
Validity and Reliability Focus
Validity- tool is measuring what
says it measures
Reliability- a tool measures the
same thing each time (inter-rater
and intra-rater)
142
On-Road Evaluation
Interrater reliability increases with
standard routes and consistent procedures
and protocols
Need for systems to observe, record and
interpret performance and more research
Challenge - great interdriver variation in
performance and behaviors
Pellerito 2006 p 262-275
143
Driver Rehabilitation
Training
To Provide Training:
Must be a Certified Driving Instructor,
licensed by the State of Ohio
Currently, must be a certified driving
school, licensed by the State of Ohio
145
Driver Rehabilitation Training
Instructor’s role is to carefully grade the
demand of driving tasks to challenge
learners without introducing situations
that are beyond their level.
Who is appropriate for training?
Client must have insight to their problem
areas for successful training.
– Simulator an option for clients with
decreased insight
146
Teen vs. Experienced Driver
Ohio Driving Instruction Curriculum
State minimum hours for teens = 8 (avg=20)
Contract with driving school who provided
classroom instruction
Training record can be inspected by Ohio
Department of Public Safety during driving
school inspection (parent must sign medical
records release for training record only)
147
Adaptations vs Non-adaptations
Driving Training
Physical issues compared to cognitive
issues.
Can be teen or experienced driver.
Adaptation training usually results in an
independent driver.
Non-adaptation training (cognitive issues)
has varied results.

Practical and Symbolic Aspects
Phases of Driving Cessation
Support Groups
150
Driving Cessation and
Alternative Community Mobility
Always ask, “How are you getting home today
if unsuccessful?”
Always provide a discussion/education and
alternatives/transportation options and
resources if a clients fails the on the road
assessment, you should never end the
assessment with, “You can’t drive anymore,”
and leave them without solutions or options.
151
Driving Cessation and
Alternative Community Mobility
“An important component of an OT’s job
is to assist the older adult who is no
longer able to drive in maintaining a high
level of health, safety, and well-being.
This assistance can include counseling,
identifying meaningful activities that do
not require driving, or providing
appropriate information sources for the
older adult.”
Pellerito 2006 p 435
152
Remember the family is important in
the final discussion.
Try to include in recommendation discussion with
client’s permission.
Encourage supporting the final decision.
Family dynamics will change based on the outcome
instantly, enable them with education.
We can be the “bad” guy for the family- minimize
resentment of caregivers.
Help with transition to retirement of driving
Help with transportation plan
Provide support for coping with the loss of driving
153
Impact of Driving Cessation
Depression - decrease social, emotional and psychological
well-being
Decrease in activities
Premature placement in long-term care facility
Forced retirement from work
Changes life roles
Feelings of regret, loss, isolation, grief
Self-identity and self-esteem affected
Decreased life satisfaction
Marker for last stage of life
154
Impact of Driving Cessation continued
Isolation-fewer trips out
Limited resources
lack of knowledge of systems
Reluctant to ask for help
Reduced access to health care and community services
Loss of mobility and independence
Decreased spontaneity-inconvenient
Disrupts lifestyle and routines
155
Driving Cessation and Alternative
Community Mobility
Men are more resistant to
relinquishing their licenses.
Men are less likely to cease
driving voluntarily.
Men are affected more in regards
to roles and self-esteem.

Driving Cessation 4 Phases
Driving in the Past-shapes meaning and identity
Predecision - some difficulty or changes to
driving routines, protects driving, challenge is
achieving awareness
Decision Phase - challenge is making the decision
and owning the decision
Post-Cessation phase- challenge is finding other
ways and coming to terms

Driving Cessation Solutions
Start Early
Before any final outcome (on the road) shift driving to
other persons
Organize errands and tasks to consolidate outings that
require rides from others
Transportation plans set up - formally, write a driving
needs list and a real schedule
162
Driving Cessation Solutions - continued
Use public transportation, taxi services.
Locate community resources available.
Arrange for deliveries.
Order from catalogs.
Arrange for home visits from beautician, etc.
Support Groups
Consider relocation to an area that has transportation.
163
Driving Cessation Barriers
Expensive alternatives (taxis and private services)
Lack of services in rural areas - absence of
alternatives
Fear of burdening social network
Most people do not plan for cessation/retirement
of driving.
Lack of flexibility to form new habits
Lack of readiness for change
164
Legal and Professional
Ethics in Driver
Rehabilitation
Autonomy
A form of personal liberty, where the individual is free
to choose and implement his/her own decisions, free
from deceit, duress, constraint, or coercion.
A competent adult has the right to refuse medical
treatment/recommendation even if the refusal is life
threatening.
What about public safety?
166
Autonomy - continued
Autonomy can be positively confirmed by being
able to answer “yes” to the following
questions:
– Does the patient understand the nature of
the illness and the consequences of the
various options that may be chosen?
– Is the decision based of rational reasoning?
The decision itself need not be rational but the
reasoning should be!
167
Autonomy - continued
A therapist/physician who is not an entity of
the state Bureau of Motor Vehicles can only
make a “medical recommendation”.
In Ohio, a therapist/physician does not have
the authority to issue/revoke a license, only
the BMV or court system can issue/revoke a
license.
168
Autonomy - continued
Is a client legal to drive home from an
appointment in which the client received a
medical recommendation for driving cessation, if
he/she has a valid driver’s license?
Is it ethical for a therapist to permit a client to
drive home after giving a medical recommendation
for driving cessation?
169
Veracity
Veracity binds both the health care
practitioner and the patient in an
association of truth.
The patient must tell the truth so
appropriate care can be provided.
The practitioner needs to disclose
factual information so that the patient
can exercise personal autonomy.
170
Veracity - continued
Quote from an ADED annual conference attendee
regarding his communication to clients whom he
is recommending driving cessation
– “I use a forceful tone of voice. The patients
do not know the difference between a medical
recommendation and having their license
revoked.”
Can a health care provider, under the guise of
doing good, purposefully mislead a patient?
171
Justice
Justice is the concept of fairness,
just deserts and entitlements.
A therapist must treat all patients
equally and fairly.
172
Justice - continued
A therapist plans to recommend an elderly client who
has suffered a CVA to a driver rehabilitation program,
as the client has stated their goal to resume driving so
he/she can return to his/her home. The client’s
daughter takes the therapist aside and requests of the
therapist not to make the referral and to recommend
driving cessation because the client lives alone and 2
hours away from any family. The daughter states her
parent is safer residing with family and she is happy to
have her parent living with her.
How should the therapist respond?
173
Role Fidelity
The ethics of health care require that
therapists practice faithfully within the
constraints of their role.
Areas of acceptable practice are contained
and prescribed by the scope of practice of
the state legislation that enables that
profession’s practice.
174
Role Fidelity - continued
In the State of Ohio, can a licensed
therapist make a medical
recommendation to a client for
driving cessation without consulting
with the physician?
175
Ohio BMV Reporting Procedures
Ohio does not have mandatory reporting
laws.
Yet, the AMA’s 1999 Code of Medical Ethics
states:
– Physicians have an ethical responsibility
to notify state motor vehicle authorities
about patients with medical conditions
that might make them unsafe drivers
(Tennery,1999)
176
Ohio BMV Reporting Procedures continued
While ethical values and legal principles are
usually closely related, ethical obligations
typically exceed legal duties.
Yet, Ohio does not protect medical professionals
who report patients from being sued for violating
HIPPA laws.
Ohio will provide anonymity to reporting
physicians but, not to any other health care field.
177
Ohio BMV Reporting Procedures continued
If a health care professional reports a patient to the
Ohio BMV – Medical Unit, the patient is notified in
writing that he/she has been reported and names the
person who reported him/her (unless reported by a
physician).
The patient must complete a form that requests the
name of his/her personal physician and return it to
the BMV.
The listed physician has 30 days to complete a BMV
form sent by the Medical Unit.
178
Ohio BMV Reporting Procedures continued
The BMV – Medical Unit reviews the physician’s
completed form then notifies the patient he/she must
retake a written and on-road examination.
Failure to complete the re-examination within a
reasonable time frame results in the BMV revoking the
patient’s license.
Patient can pass or fail the re-examination.
The patient is permitted 3 attempts to pass the re-
examination.
During the time frame of this process, the patient
maintains his/her valid license.
