Although the DOT physical exam requirements do not include a drug test, your employer may request that you have a drug screen done while you take your DOT physical. You will be required to submit a urine sample. This is used to test for drugs and screen your kidneys for potential medical conditions. Let Winters Chiropractic handle everything you need during your DOT or CDL physical. Our top priority is to provide the best service possible to all clients no matter the reason for their visit
