must have a diabetes exemption issued by which entity?
A) An endocrinologist
B) The Medical Examiner
C) The driver's personal physician
D) The FMCSA
Answer: D
Explanation: Only the Federal Motor Carrier Safety Administration (FMCSA) has the
authority to grant medical exemptions, including diabetes exemptions for drivers with
insulin-treated diabetes mellitus. Medical examiners, endocrinologists, and personal
physicians cannot issue these exemptions. The FMCSA conducts an individualized review of
each application, considering the driver's medical history, glucose control, and absence of
severe hypoglycemic episodes before granting an exemption.
2. Which of the following is a requirement for drivers operating under a diabetes
exemption?
A) Possess a rapidly absorbable form of glucose while driving
B) Self-monitor blood glucose one hour before driving and at least once every two hours
while driving
C) Plan to submit blood glucose monitoring logs every six months
D) Maintain a hemoglobin A1C value of less than 7%
Answer: A
Explanation: Drivers with a diabetes exemption must carry a rapidly absorbable form of
glucose while driving to treat potential hypoglycemic episodes. Under FMCSA guidelines,
drivers with insulin-treated diabetes who have been granted an exemption are required to
self-monitor blood glucose one hour before driving and at least once every four hours while
driving. Blood glucose monitoring logs are typically submitted annually as part of the
exemption renewal process.

and has been granted a diabetes exemption may be certified for which maximum
period?
A) Three months
B) Six months
C) One year
D) Two years
Answer: C
Explanation: Drivers with insulin-treated diabetes mellitus who are otherwise medically
qualified and have been granted a diabetes exemption may be certified for a maximum of one
year. The driver must provide at least three months of self-monitoring blood glucose data
from an electronic glucometer with timestamps to qualify for a 12-month certificate. The
diabetes exemption itself is typically valid for up to two years.
4. What is the recommended certification interval for a driver with diabetes mellitus
who does not use insulin?
A) Three months
B) Six months
C) One year
D) Two years
Answer: C
Explanation: Drivers with non-insulin-dependent diabetes should be certified for a
maximum of one year. The medical examiner must evaluate whether the driver's diabetes is
controlled, assess for complications that may affect safe driving, and review recent laboratory
results including fasting blood glucose and hemoglobin A1C.
5. A driver with a history of insulin-treated diabetes is determined to be otherwise
medically qualified. Where must the Medical Examiner indicate that a diabetes
exemption is required?
A) Medical Examination Report status section and Medical Examiner's Certificate

D) Endocrinology consultation form
Answer: A

both forms that the driver requires a diabetes exemption. The driver then applies directly to
the FMCSA for the exemption.
6. Which of the following is a disqualifying criterion for drivers with a history of
diabetes?
A) One severe hypoglycemic reaction in the past year
B) Two severe hypoglycemic reactions in the past five years
C) Both A and B
D) Hemoglobin A1C greater than 8%
Answer: C
Explanation: A driver should not be certified if they have had one severe hypoglycemic
reaction in the past year or two severe hypoglycemic reactions in the past five years. The
FMCSA defines a severe hypoglycemic reaction as one that results in seizure, loss of
consciousness, need of assistance from another person, or a period of impaired cognitive
function that occurred without warning.
7. Which diabetes-related condition poses the greatest threat to public safety for CMV
drivers?
A) Hyperglycemia
B) Peripheral neuropathy
C) Hypoglycemia
