Preston, TX DOT Physical - What You Need to Know

A DOT physical is a thorough health evaluation mandated by the Department of Transportation (DOT) for all commercial motor vehicle (CMV) operators. This assessment ensures that drivers are in a condition suitable for handling large vehicles on public roadways. Conducted by a certified medical examiner (CME) listed on the National Registry of Certified Medical Examiners (NRCME), passing this exam grants drivers a DOT medical certificate (Medical Examiners Certificate or DOT medical card), essential for keeping a valid CDL per FMCSA rules. For assistance with DOT physical requirements, contact 800-221-4291.

During your exam, the medical examiner will complete a thorough health assessment to determine if you meet the Federal Motor Carrier Safety Administration (FMCSA) medical standards. The process typically includes:

What Will Fail a DOT Physical?

Medical Conditions That Can Fail a DOT Physical

  • Vision & Hearing: If vision is worse than 20/40 in either eye with correction, inability to differentiate traffic light colors, or hearing loss stopping a forced whisper at 5 feet, it may affect qualification.
  • Blood Pressure & Heart Disease: Unmanaged high blood pressure (≥180/110 mmHg), recent heart attack, stroke, unstable angina, or a non-cleared defibrillator placement can threaten eligibility.
  • Diabetes: Poor diabetes control, recurrent hypoglycemia, or complications like neuropathy and visual issues that impact safe driving pose risks.
  • Sleep Apnea & Respiratory Issues: Unaddressed sleep apnea causing daytime sleepiness or severe lung disease reducing oxygenation may lead to disqualification.
  • Neurological Disorders: Epileptic or seizure disorders without exemption, or any condition causing unexpected consciousness loss, dizziness, or involuntary tremors can be disqualifying.
  • Substance Abuse: Current use of illicit drugs, alcohol dependency, or prescription misuse impairing driving skills can result in immediate disqualification.
  • Psychiatric & Cognitive Disorders: Serious psychiatric illnesses like untreated schizophrenia or recent severe bipolar episodes, as well as cognitive impairments impacting judgment, may result in disqualification.

Classification of disqualification into temporary or permanent is crucial. Conditions that might be temporarily disqualifying can be reversed with medical documentation or clearance (e.g., managed blood pressure or diabetes control). However, untreated seizure disorders or defibrillator implants are generally seen as permanently disqualifying under FMCSA rules.

Accredited has been wonderful to work with!

Accredited has been wonderful to work with! My court ordered tests are on a very strange schedule but every time I call, they are quick to schedule me and are always able to find a location that works for where I’m at and when! Thank you for making this rather undesirable situation less stressful and efficient.
