The Department of Transportation is responsible for all public roads and the safety condition of the roads. The DOT also does many other things involved with transportation in a given state. Commercial truck drivers need to be fully alert and ready for the long drives. If, for example, drivers have sleep apnea, it can look like they are on drugs and driving is affected, potentially to a severe degree. Though these drivers are not using drugs, it is important to spot them before any accidents happen.
Who is going to stop them and get them to go see a doctor? The dot medical examiners handle that situation. It is possible to become a fully licensed medical examiner with the proper classes and training. Anyone can do this, but it is typically reserved for commercial drivers. It is just one more good item to put on the resume and may get you higher pay, though this is not a guarantee.
Should you want to get certified as a medical examiner, you have to be in good health yourself. Don’t be surprised if you have to do some medical tests. This is just the DOT way to determine if you are qualified for the learning and the task. We don’t want any bad drivers on public roads. As a result, you will find that the training is strict. You don’t get this certification overnight. It will take work and studying which is all worth the effort.
With this certification, you will learn how to spot drivers who are making mistakes, for the safety of the drivers and roads. Any poor driving is not acceptable. You will at least be able to determine the cause of the faulty driving. It is probably a physical condition that requires medical treatment. When the treatment is successful and the doctor provides a release/discharge form, drivers can go back to driving.
