In order to operate a commercial motor vehicle (CMV), a physical examination is required. The Federal Motor Carrier Safety Administration (FMCSA), a department of the United States Department of Transportation (DOT), sets the standards of a DOT physical exam. A physical exam must be performed only by a certified medical examiner.
Driving large tankers, trucks, buses, and long limousines can be a physically challenging occupation. According to the Department of Transportation, to acquire a commercial driver’s license (CDL), completing the CDL training and passing the DOT physical is mandatory. It ensures that you are physically capable of operating large commercial vehicles. Learn more about the DOT exam and find DOT medical examiner locations near you.
The DOT medical examination
Only a certified medical examiner can perform the DOT physical exam. The physician will check your medical history and ask questions about your lifestyle and what medications you are taking. The exam also includes:
- A vision check. Truck drivers must have 20/40 vision in each eye.
- A blood pressure test. Blood pressure must be at or below 140/90 with or without medication to be a truck driver for a 2-year certification.
- A hearing test where you are tested if you can hear a forced whisper from five feet away. This test ensures that your hearing is okay.
- A reflex and movement exam. The DOT medical examiner will check for things that could impair your movement, such as spinal deformities.
- Lung function assessment. If you have a respiratory problem, like asthma, you may need another lung test.
- A neurological exam. During this part of the test, the doctor will check your reflexes and coordination. The doctor will also check for neurological issues that could affect your ability to drive. If you have epilepsy or another seizure disorder, you will be disqualified from getting a DOT medical examination.
During the DOT physical exam, you will also give a urine sample for a urinalysis. Through urine testing, underlying issues, such as kidney disease or diabetes mellitus can be determined. Your sample will not be used for drug testing. A drug test is only done upon the request of your employer.
