DOT Physical Requirements in Colorado: Checklist for Drivers and Employers

Who needs a DOT physical, what the exam covers, what to bring so you leave certified, and how long your card lasts — a practical checklist for CDL drivers and Colorado fleet employers.

Commercial truck driver having his blood pressure checked during a DOT physical

Key takeaway: Commercial drivers must pass a DOT physical performed by a medical examiner on the FMCSA National Registry. Certification lasts a maximum of 24 months — shorter if a condition needs monitoring. Bring your medication list, glasses or contacts, hearing aids, and recent CPAP data if you use one; missing items are the most common reason a certification gets delayed.

This guide is for CDL drivers due for an exam and for Colorado fleet and trucking employers building a compliant medical certification program.

Who Needs a DOT Physical?

Federal rules (49 CFR Part 391) require a current medical certificate for drivers operating in interstate commerce who drive a vehicle over 10,000 lbs GVWR, transport hazardous materials requiring placards, or carry passengers (9+ for compensation, 16+ otherwise). Colorado applies federal medical standards to intrastate CDL drivers as well, with limited exceptions. [COMPLIANCE VERIFY current CO intrastate variances]

The exam must be performed by a certified medical examiner listed on the FMCSA National Registry — not just any clinic. [Confirm and name ICA’s certified examiner(s) here — this is an E-E-A-T win.]

What the Exam Covers

A DOT physical is a fitness-for-duty exam, not a general checkup:

  • Vision: at least 20/40 in each eye and both together (corrective lenses allowed), with adequate peripheral vision
  • Hearing: forced-whisper test at 5 feet, or audiometric standards (hearing aids allowed)
  • Blood pressure and pulse: elevated BP can still certify, but typically for a shorter period with monitoring
  • Urinalysis: checks protein, blood, and sugar as health indicators — this is not a drug test
  • Medical history review: medications, surgeries, sleep apnea, cardiac history, diabetes, seizures
  • Physical exam: heart, lungs, abdomen, spine, neurological function, hernia check

What to Bring: The Checklist

  1. Complete medication list — names, doses, prescribing doctors
  2. Glasses, contacts, or hearing aids you use
  3. CPAP compliance data (usually 90 days) if treated for sleep apnea
  4. Recent lab results / specialist letters for managed conditions (diabetes, cardiac, seizure history)
  5. Your driver’s license
  6. If insulin-treated diabetic: completed FMCSA insulin-treated diabetes form from your treating clinician [VERIFY current form number/process before publish]

Showing up without documentation doesn’t usually mean failing — it means a delayed or shortened certification while the examiner waits for records. Bring the paperwork; leave certified.

How Long Certification Lasts

Maximum 24 months. Examiners commonly issue shorter cards — often 12 months, sometimes 3 or 6 — for conditions that need monitoring, such as managed hypertension. Build renewal timing into your calendar at least 30 days before expiration; a lapsed card means a parked truck.

Conditions That Require Monitoring — or Disqualify

Honesty up front saves drivers grief: some findings require treatment or documentation before certification (uncontrolled high blood pressure, untreated sleep apnea, poorly controlled diabetes), and a small number are disqualifying under federal rules (e.g., epilepsy not meeting exemption criteria, current alcohol dependence without recovery documentation). A good examiner’s job isn’t to fail drivers — it’s to get treatable issues managed so the driver certifies safely. [CLINICIAN REVIEW this section closely]

For Employers: Building a Fleet Program

Tracking expirations across a fleet is where compliance breaks down. A clinic partner can schedule renewals on a cycle, deliver results the same day, and coordinate DOT physicals with drug and alcohol testing in one visit — one stop per driver, per cycle.

Where ICA Fits In

ICA performs DOT physicals with FMCSA-certified examiners [VERIFY + name], with same-day certificates for qualified drivers. Drivers: schedule your DOT physical. Fleet managers: ask about a fleet certification program.

FAQ

Is the DOT urinalysis a drug test? No. The urinalysis in a DOT physical screens for medical indicators like sugar and protein. DOT drug testing is a separate program with its own collection rules — though both can often be done in the same visit.

Can I get a DOT physical if I have high blood pressure? Usually yes. Depending on your readings you may receive a shorter certification period with follow-up monitoring rather than a denial. Bring your medication list and recent readings. [CLINICIAN VERIFY current staging thresholds]

How long does the exam take? Typically 30–45 minutes with complete paperwork. Missing documentation is the main thing that stretches it into days.
