2. OBJECTIVES
Understand the safety risks of older drivers
Indentify conditions that may put older drivers at
risk
Indentify the role of the physician
Demonstrate familiarity with the law as well as
California DMV reporting methods and
requirements
4. Taxonomy of Older Driver
Behaviors and Crash Risk from
NHTSA Feb 2012
Identify risky behaviors, driving habits
and exposure patterns that have been
showed to increase the likelihood of
crash involvement
Crash types where older drivers were
most strongly overrepresented
2002-2006 using database from FARS
and NASS
5. Taxonomy of Older Driver Behaviors and Crash
Risk from NHTSA Feb 2012
Older people were increasingly less likely to be driving the striking
vehicle in a two vehicle crash
High – speed two lane roadways and multilane roads with speed limits
of 40-45 mph were associated with heightened older driver crash
involvement
In two vehicle crashes, failure to yield was the most frequently cited
factor
Starting at age 70, old drivers were specially likely to crash at
intersections
With respect to single vehicles crashes , older drivers were somewhat
more likely to be identified as ill or blacking out, drowsy or asleep, using
medications or drugs ( other than alcohol), and having some other
physical impairments ( hearing loss)

9. Older drivers have an increased likelihood of being injured or
killed in a crash.
L. Evans Traffic Safety (2004), Bloomfield Hills, MI: “Science Serving Society”
11. Automobile crashes are the third leading cause of
death and injury in the United States with 40,000 to 50,
000 people killed in about 2 million accidents per year
Drivers over age 75 had a higher rate of fatal accidents
nationwide in 2001- 2002. This problem is expected to
grow because by 2024, one in four U.S. drivers will be
over age 65
National Older Driver Research and Training Center
Physicians are in a unique position to anticipate the impact
of physical and mental conditions on driving
impairment.
12. The privilege of driving is a source of freedom and
empowerment for many individuals. Removing this
privilege has its risks.
The loss of ability to be independently mobile can be a
devastating psychological blow for an elderly patient. It
also may restrict a patient access to meet medical and
social services or to employment venues.
14. CEJA of the AMA report on impaired drivers and
their physicians: I-99
Physicians have an ethical responsibility to assess patients’
physical or mental impairments that might adversely affect
driving abilities
Each case must be evaluated separately since not all
impairments may give rise to an obligation on the part of the
physician
The physician must be able to identify and document
physical or mental impairments that clearly relate to the
ability to drive
The driver must pose a clear risk to the public safety
15. Recommendations
1. Physicians should assess patients’ physical or mental
impairments
3. Before reporting, there are a number of initial steps
physicians should take
5. Physicians should use their best judgment when determining
when to report impairments that could limit a patient’s ability
to drive safely.
7. The physicians role is to report medical conditions that would
impair safe driving. The determination of the inability to drive
safely should be made by the states DMV.
16. Recommendations
1. Physicians should disclose and explain to their patients this
responsibility to report
3. Physician should protect patient confidentiality by ensuring
that only the minimal amount of information is reported
5. Physicians should work with their state medical societies to
create statues that uphold the best interests of patients and
community, and that safeguards physicians from liability
when reporting in good faith.

COGNITION
Trail B: Lafont confirmed a high correlation between increasing
age and poor attentional and executive performance, as
measured by Trail-Making B, to be correlated with both crashes
and driving cessation (Lafont, 2008).

MCI = 136 sec
Dementia = 190

21. Clock drawing test using Freund Scoring Criteria
YES NO
Only the numbers 1-12 are included
Number inside the clock
Numbers are spaced equally from each other
Numbers are spaced equally from the edge
One clock hand correctly points to 2
There are only 2 clock hands
There are no intrusive marks, writing or hands
indicating incorrect time
The scoring is based on seven “principal components” which
were derived by analyzing the clock drawing of 88 drivers 65
and older against their performance on a driving simulator
(Freund 2005).
22. Counseling the patient / family
Physicians are influential in a patient’s decision to
stop driving; in fact advice from a doctor is the most
frequently cited reason that a patient stops driving.
Persson, D. (1993)

24. What do with a difficult patient?
i Encourage patient to complete the self screening
tool
t Counsel your pt on Successful aging tips and tips
for safe driving
o Roadwise review
http://www.seniordrivers.org/driving/driving.cfm?button=roadw
r DOCUMENT your concerns and support this with
relevant information. Document patient reactions
along with any counseling you have provided.
28. California Code of regulations (CCR) title 17 sub-chapter 2.5
“Disorders characterized by lapses of consciousness” sections
2800-2812.
“Reporting the local health authority” the non-communicable disease or
conditions – AD- and related conditions and disorders characterized by
lapses of consciousness .
2802 AD and related disorders. Means those illnesses that damage the brain
causing irreversible, progressive, confusion, disorientation, loss of memory
and judgment
2806 Disorders characterized by lapses of consciousness.
Loss of consciousness or a marked reduction of alertness or responsiveness to
external stimuli
inability to perform one or more ADLs
the impairment of the sensory motor functions used to operate a motor vehicle
EX: OSA, abnormal metabolic states (DM)
29. Important issues about the regulations:
They are specific to physicians and surgeons per section
103900 of the Health and Safety Code
The physicians who reports a patient diagnosed with a
disorder characterized by lapses of consciousness,
according to the Health and Safety code 103900, shall not
be civilly or criminally liable to any patient for making the
report.
30. Liability
Physicians are considered negligent if they do not inform
patients of medications and medical conditions that can
impair driving
○ Physicians may be held liable for civil
damages if they clearly failed to report an
impaired driver who causes a MVC
○ Immunity is granted to the physician if the
patient is reported prior to a MVC
○ Document all referrals, recommendations,
conversations, and reports (e.g. copy of a
driver retirement letter and “do not drive”
prescription)
31. California
Individuals 70 years of age and older
Must renew license in-person
License is renewed for five years if vision and written tests are
passed and there are no signs of cognitive impairment
A “limited term” license may be issued for one to two years if a
medical problem exists but is not severe enough to stop driving
(e.g. mild dementia)
Dementia moderate-severe = DL revoked
Dementia early or mild = Reexamination
In this manner, the California DMV hopes to balance the need for
public safety and with the perseveration of personal independence .
32. Reporting…….
In California in 1988 , healthy and safety code section 410
added AD and related disorders to the list of conditions that
physicians are required to report to their local health
departments, which then forward this information to CA
DMV.
Based on the results of these examinations as well as a
physician completed written driver medical evaluation (DME)
form the DMV could allow the driver to:
Continue driving unrestricted
Continue driving with restrictions
Revoke or suspend DL.
34. Safety, mobility and cost are critically important
Physician role is difficult: caseloads, poor training
Limited alternatives to driving
Recognize rights and feelings of older people
Many obvious solutions may not work very well
We started addressing this problem too late
35. "Above all, we must work together to ensure that
older adults can remain mobile and productive
even when they have to give up driving.“
Thomas Meuser, Ph.D.
Research associate professor of neurology at Washington University.

Hinweis der Redaktion
National highway traffic safety administration A notable data found on the data reviewed were crash involvement ratios for older age groups that did not bear out conventional wisdom about certain situations being especially risky for these drivers, such as merging, changing lanes, driving on I Highways and driving in bad weather. VERY MIXED BAG, VERY SICK AND VERY HEALTHY
On a licensed driver basis, older adults are among the safest on the road. The average annual number of crashes in the United States is 68 per 1,000 licensed drivers, while the corresponding rate for drivers aged 65 and older is only 37. The picture changes somewhat when crash rates are calculated on the basis of miles traveled. Using this measure of exposure, older adults are at increased crash risk . The increase in risk is evident for 65-74 year olds, but becomes even more pronounced with increased age.
Coincides with the increase in incidence of dementia
Council on ethical and judicial affairs
2. Ex : referrals, restrictive driving 3. Clear evidence and where the advice of to discontinue driving is ignored
First edition was published on 7/30/2003 and updated on 2/3/2010. The information on this guide is provided to assist physicians in evaluating the ability of older patients to operate motor vehicle safely as part of their everyday personal activities. Is not intended as a standard of medical care, nor should it be used as a substitute for physicians clinical judgment. It reflects the scientific literature and views of experts as of December 2009.
You may counsel your patient about driving when you Prescribe a new medication or change doses, treat Unstable medical condition or work up a new onset
The specific functional deficits related to crashes in the older adult were attention and cognition
The interpretation of Trail Making is very simple: a time of greater than 180 seconds is a failure. However, screening tests for dementia can result in false positives due to depression, visual impairment or metabolic disorders such as hypoglycemia. Medications can also interfere with cognitive function on a temporary basis . But if other false positives don ’t exist, dementia is likely and the patient may need to be reported to the DMV with or without further testing.
Not timed. Assess LTM, STM, visual perception, visuospatial skills , selective attention and executive skills Sensitivity and Specificity: 85% If used in combination with the three-word delayed-recall, sensitivity and specificity reach 93% Depression has little effect on clock drawing, although false positives can occur from depression or medication
2. ensure your patient understands the reasons (legal, healthy and safety).Use the term “driving retirement” vs “giving up”. Pt may benefit from the visual reinforcement of a rx with the words “Do Not Drive.” 4. . Asses pt ability to comply , transportation resources your patient has identified and look for signs of isolation or depression
