What Will Fail a DOT Physical?

Medical Conditions That Can Fail a DOT Physical

  • Vision & Hearing: Failing to meet 20/40 vision in each eye (even with correction), unable to identify traffic signals' colors, or hearing loss not allowing recognition of a forced whisper at 5 feet can cause disqualification.
  • Blood Pressure & Cardiac Conditions: Unchecked hypertension (≥180/110 mmHg), past heart attack, stroke, uncontrolled angina, or a defibrillator without appropriate clearance are grounds for disqualification.
  • Diabetes: Out-of-control diabetes causing regular hypoglycemia or complications like neuropathy and impaired sight can hinder safe driving.
  • Sleep Apnea & Respiratory Issues: Untreated sleep apnea leading to daytime drowsiness or severe respiratory diseases impairing oxygenation could disqualify.
  • Neurological Disorders: Conditions such as epilepsy (unless exempted), abrupt consciousness losses, dizziness, or unmanageable tremors might disqualify.
  • Substance Misuse: Active illegal drug use, alcohol dependence, or prescription misuse affecting driving capability is disqualifying.
  • Mental & Cognitive Disorders: Severe, unmanaged psychiatric conditions (e.g., schizophrenia, bipolar disorder with recent episodes) or cognitive deficits that impair judgment and reaction are disqualifying.

Issues resulting in temporary disqualification may be addressed by providing medical documentation, like managed blood pressure. Conversely, untreated seizure disorders or defibrillators often result in permanent disqualification under FMCSA guidelines.

Where do I start?!! ADT is truly the best!! I had the pleasure of speaking with Tori today! She was excellent, professional and truly went above and beyond in her kind, compassionate care and commitment to providing me with the best service possible.

Sophia Schutze - 6/19/2024

ADT was able to get me the best tests

Dealing with allegation’s of drug use that completely false is stressful, ADT was able to get me the best tests, going back the farthest in the same day with as little hassle as possible, I spoke with 1 person and wasn’t transferred once, and they took my payment, and got me my work order for a clinic as close as possible for the service I needed. 5*

Christopher Hansis - 12/19/2024

This is by far the easiest

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
