How to Pass Your CDL Medical Exam in Florida: A Driver’s Checklist

If you're aiming to get or renew your commercial driver’s license (CDL), passing a CDL medical exam in Florida, also known as a DOT physical, is one of the first steps. This federally required exam helps ensure you're healthy enough to safely operate a commercial vehicle. But it can feel a little intimidating—especially if it’s your first time.

At Harmony Health Clinic in Naples, FL, we’ve helped countless drivers pass their DOT physicals with ease. This guide will walk you through what to expect, how to prepare, and the key things to bring so you can walk in confident—and walk out certified.

What Is a CDL Medical Exam?

A CDL medical exam is a health screening mandated by the Federal Motor Carrier Safety Administration (FMCSA). It's required for anyone operating a commercial vehicle across state lines or transporting passengers or hazardous materials.

This exam must be conducted by a certified medical examiner listed on the FMCSA National Registry.

You’ll receive a Medical Examiner’s Certificate (MEC) if you pass, which is good for up to 2 years max, depending on your health conditions.

Who Needs a CDL Medical Exam in Florida?

You need a DOT physical if you:

• Drive a vehicle with a GVWR of 10,001 pounds or more

• Transport 8+ passengers for compensation, or 15+ without

• Carry hazardous materials

• Operate a vehicle interstate or intrastate, depending on Florida CDL requirements

  
  

What to Bring to Your Exam

Here’s a checklist of what to bring to your DOT physical:

• A valid photo ID (driver’s license)

• Eyeglasses or contacts, if you wear them

• Hearing aids, if needed

• A list of your current medications, including doses

• Your most recent medical records if you have a chronic condition (like diabetes, sleep apnea, or heart disease)

• If you use a CPAP machine, bring a printout showing compliance (usually 90 days)

• Recent lab results or clearance letters from specialists, if applicable

• Your last MEC card, if renewing

• A full bladder – you’ll need to provide a urine sample

What Happens During the CDL Medical Exam?

The exam typically takes 30–45 minutes and includes:

1. Health History Review

• Past surgeries, conditions, medications

• Symptoms like dizziness, shortness of breath, or fatigue

2. Vital Signs & Physical Exam

• Blood pressure

• Height and weight

• Pulse and respiration

• Vision and hearing tests

• Reflexes and mobility

3. Urine Test

• Screens for protein, blood, or sugar (not drugs unless required separately)

• Helps flag kidney disease or diabetes

Common Health Concerns (and How to Manage Them)

Blood Pressure

• Must be under 140/90 to qualify for a 2-year card

• Controlled high blood pressure may still be certifiable for 1 year

Vision

• At least 20/40 in each eye, with or without correction

• Peripheral vision of at least 70 degrees in both eyes

Hearing

• Must hear a forced whisper from 5 feet

• Hearing aids are allowed if they meet the threshold

Blood Sugar

• Diabetics using insulin must comply with FMCSA requirements and bring necessary paperwork

Sleep Apnea

• If diagnosed, you must show treatment compliance with CPAP data

Pro Tip: If you have any condition that could be a red flag, bring specialist clearance letters and documentation showing that it's well-managed.

Florida-Specific CDL Tips

In Florida:

• Intrastate-only drivers may still need a DOT physical, depending on job requirements

• CDL medical cards must be submitted to the Florida Department of Highway Safety and Motor Vehicles (FLHSMV)—check their website for upload instructions

• CDL holders must self-certify (interstate or intrastate) when submitting their MEC

For local drivers in Naples, Harmony Health Clinic offers same-day appointments, quick turnarounds, and paper or digital copies of your MEC.

How to Prepare the Day Before

Set yourself up for success with these simple steps:

• Avoid salty foods and caffeine the night before (can affect blood pressure)

• Get a good night’s sleep

• Drink water—you’ll need to provide a urine sample

• Don’t forget your meds (and bring a list)

• Arrive 10–15 minutes early

What If You Don’t Pass?

If something prevents you from passing, don’t panic. In many cases, it's a temporary disqualification—not permanent. Most issues (like high blood pressure or missing documentation) can be corrected, and you can return for a recheck.
