What Can Fail a DOT Physical?
If you have a DOT physical coming up, it’s normal to feel a little nervous about whether you’ll pass. One of the most common questions we hear at Mountain Movement Chiropractic is, “What can actually fail me on a DOT physical?” The goal of the exam is not to take drivers off the road unnecessarily. It’s to make sure you can operate a commercial vehicle safely. Most drivers who are prepared and managing their health pass without issue.
Knowing what the examiner looks for ahead of time can help reduce stress and prevent delays.
The Most Common Reasons Drivers Do Not Pass
Certain medical conditions can disqualify a driver temporarily or require additional documentation before certification is issued. High blood pressure is one of the most common issues. Elevated readings may result in a shorter certification period or require follow-up care before full clearance. Managing blood pressure ahead of time makes a big difference.
Vision problems are another frequent concern. Drivers must meet minimum visual acuity and peripheral vision requirements. Forgetting corrective lenses or having an outdated prescription can delay certification even if your vision is usually adequate.
Uncontrolled diabetes can also affect DOT certification. Drivers who use insulin or have poorly controlled blood sugar may need additional paperwork or monitoring. This does not automatically mean failure, but it does require proper documentation.
Conditions That Often Cause Delays, Not Failures
Many drivers worry that common issues like back pain, joint stiffness, or prior surgeries will automatically fail them. In most cases, these conditions do not disqualify you as long as you can safely perform job duties. The examiner looks at function, not perfection.
Sleep apnea is another condition that raises questions. If it is diagnosed and properly treated, many drivers still qualify. The issue arises when sleep apnea is untreated or when documentation is missing.
Medications can also cause delays. Certain medications are allowed, but the examiner must confirm they do not impair alertness or reaction time. Bringing a current medication list helps avoid problems.
What Will Not Automatically Fail You
Having a medical condition does not automatically mean you will fail a DOT physical. Many drivers with high blood pressure, diabetes, prior surgeries, or chronic pain are certified every day. The key factors are stability, control, and documentation.
The DOT physical is about safety, not punishment. Most issues can be addressed or managed with the right preparation.
How to Improve Your Chances of Passing
Getting a good night of sleep before your exam helps normalize blood pressure and improves overall exam results. Staying hydrated, taking prescribed medications as directed, and avoiding stimulants before your appointment can also help.
Bringing required items such as corrective lenses, hearing aids, medication lists, and relevant medical records can prevent unnecessary follow-ups. If you know you have a condition that may raise questions, preparation is the best strategy.
