I decided to keep my CDL even though I am not driving any big rig anymore. I had been skipping the medical exam for a few years. I passed my physical which included the urine test of course. Going forward, what about random urine tests? In the past, my employers used a computer program to generate random employee lists to get tested. For anyone the same situation or perhaps self employed, what do you do to meet this requirement? I did not think to ask my provider.
Something else that I learned about how often I must get an exam. After I retired, I drove a school bus for a few years. At that time, the "S" endorsement holders had to be examined yearly. July 1, 2023, that had changed to every two years. However, because I take certain medications I must still get examined every year.
