Why is the DOT physical examination important?

The USDOT physical examination is required to help ensure that a person is medically qualified to operate a commercial motor vehicle safely. In the interest of public safety, commercial motor vehicle drivers are generally held to higher physical, mental and emotional standards than passenger car drivers.

What medical criteria are required to obtain a medical certification?

Please visit Federal Motor Carrier Safety Administration (FMCSA) website.

What is the Federal Motor Carrier Safety Administration (FMCSA)?

Effective Jan. 1, 2000, the Motor Carrier Safety Improvement Act of 1999 created the Federal Motor Carrier Safety Administration (FMCSA) as a separate administration within the U.S. Department of Transportation. The primary mission of FMCSA is to reduce crashes, injuries and fatalities involving large trucks and buses. FMCSA is headquartered in Washington, D.C., and employs more than 1,000 individuals in all 50 states, the District of Columbia and Puerto Rico. For more information, go to About FMCSA on the FMCSA website.

What is the procedure if the DOT Medical Examination Report and/or Medical Examiner Certificate is damaged, is lost or cannot be read?

A copy should be on file in the medical examiner's office. You may request a replacement copy from the medical examiner, or a copy may be available from your employer.

For how long is my medical certification valid?

A medical certification is valid for two years, unless otherwise specified for a shorter period by the medical examiner.

Am I prohibited from operating a commercial vehicle if I have a medical condition that developed after my last medical certificate was issued?

You are required to notify us of a physical condition that develops or worsens, causing noncompliance with the CDL physical qualifications, as soon as your medical condition allows. Once the medical condition is resolved and before resuming operation of commercial vehicles, you are responsible for obtaining recertification from a medical examiner.

What happens if a driver is not truthful about the health history on the DOT Medical Examination Report?

The FMCSA medical certification process is designed to ensure drivers are physically qualified to operate commercial vehicles safely. Each driver is required to complete the Health History section on the first page of the examination report and certify that the responses are complete and true.

The driver must also certify that he or she understands that inaccurate, false or misleading information may invalidate the examination and medical examiner certificate. Deliberate omission or falsification of information may invalidate the examination and any certificate issued based on it. A civil penalty may also be levied against the driver under 49 USC 521(b)(2)(b), either for making a false statement or for concealing a disqualifying condition.

What medications disqualify a CDL driver?

You cannot take a controlled substance or prescription medication without a prescription from a licensed practitioner.

You are not qualified if you use a controlled substance identified in 21 CFR 1308.11 Schedule I, an amphetamine, a narcotic or any other habit-forming drug.

There is an exception. The prescribing doctor can write that you are able to operate a commercial vehicle safely while taking the medication. In this case, the medical examiner may, but does not have to, certify the driver.

Note: Any medication used for the prevention of seizures is disqualifying.

Is the medical examiner required to repeat the entire physical examination if the driver is only returning for a blood pressure check?

This decision is made at the discretion of the medical examiner; if the driver returns to the same medical examiner within the time required, the CDL driver is not required to repeat the entire physical examination. However, if the medical examiner is to extend the certification, it must be extended from the original date of exam, and a new certification card must be completed.

Does Arizona have an Insulin-Dependent Intrastate Waiver?

No. A driver is disqualified if any form of insulin is used.

Is the use of Byetta disqualifying for CDL drivers?

No. Byetta is a noninsulin injection.
