The CDL medical exam, often called a DOT physical, is a checkup required by the Federal Motor Carrier Safety Administration (FMCSA) to make sure you’re fit to drive big rigs or other commercial vehicles. It’s mandatory for anyone with a CDL, and you typically need to renew it every two years—sometimes sooner if you’ve got health issues. Here’s what it covers: A certified medical examiner (listed on the FMCSA’s National Registry) starts with your medical history—think past surgeries, conditions like diabetes or sleep apnea, and any meds you’re on. Then comes the physical: they check your vision (at least 20/40 in each eye, with or without glasses, and 70-degree peripheral vision), hearing (you need to hear a whisper from 5 feet or pass an audiogram), blood pressure (ideally under 140/90), and general physical ability—no major issues with limbs, heart, lungs, or nerves that’d impair driving. They’ll also do a urinalysis to screen for stuff like high blood sugar or kidney problems, but it’s not a drug test unless your employer adds that separately. Our doctor will provide you with a quick and easy process to help you get your CDL.
