Do DOT Physicals Feature a Drug Test?

If you're a commercial motor carrier, then you know that DOT physical exams are an essential part of your job. These exams must get completed every two years. This is to ensure that you remain healthy enough to operate a motor vehicle. Certified medical examiners will test you for a wide range of medical conditions. Then, they will issue a medical card upon successful completion. So keep up with your DOT physicals – it could save your life. Say that you're undergoing a DOT physical exam. It's important to understand what types of tests you'll get subjected to. Sure, you will need a standard physical. But the examiner will also request a urine sample. This sample gets used to screen for common medical conditions. Diabetes is a common condition. What is MC Number? Detecting drug use is not a central component of the physical. (Unless you've gotten asked by your employer to take a pre-employment drug test at the same time.) The examiner should make sure you're aware of testing procedures during your appointment. So, does a DOT physical include a drug test? Not in a specific manner. But sometimes drugs show up through medical readings. Also, take a look at the Drug and Alcohol Program policy.

How Do Medications Impact the Test?

Here's how a DOT physical works. A medical examiner will begin by assessing your current medications. This is to determine if any of them may disqualify you from operating a commercial motor vehicle. The physical includes medications taken for diabetes, heart disease, and neurological conditions. Or, mental health issues and even recent surgeries. Say a medical examiner decides any medications might affect your ability to drive. Visit BOC-3 Filing. The examiner might need a note from your doctor. This note can explain your condition. Plus, it will detail the impact the medication could have on your driving. Sometimes a temporary disqualification may get issued. This happens if the medical examiner makes a specific judgment. He or she can deem medications can't get used while driving a commercial motor vehicle. You may then get reevaluated for a medical card once you've been off the medication for a certain period of time. In some cases, you may still receive a medical card. But you'll need to have another DOT physical exam within 6-12 months instead of the usual 2-year timeframe. Keep in mind that DOT testing policies can change year-to-year. For example, the DOT physical urine test in 2022 changed from 2021. Read here about Starting a Trucking Company Correctly.

What Do They Test in Urine for the DOT Physical?


The urine sample collected for the DOT physical includes a urinalysis. This tests for glucose, ketones, specific gravity, and pH level. Also, blood gets tested for protein levels and creatinine. Why? To identify any possible kidney problems. This helps detect conditions such as diabetes, kidney disease, or urinary tract infections. The results of these tests must meet certain standards. Otherwise, you cannot pass the DOT physical examination. Say abnormalities get found in the test results. Further testing may be required before receiving clearance from the medical examiner. visit DOT Authority Package, Tips to prepare for 2023 DOT Week filings in minutes.
