How to Prepare for a DOT Physical
If you're a commercial driver in the U.S., passing a DOT physical is not just a requirement — it's your license to keep working. Mandated by the Federal Motor Carrier Safety Administration (FMCSA), this medical exam ensures that you're physically and mentally fit to safely operate a commercial motor vehicle (CMV).
Whether it's your first time or a routine renewal, preparing properly for your DOT physical can make the process smooth and stress-free. Here’s what to expect and how to get ready.
What is a DOT Physical?
A DOT (Department of Transportation) physical is a health exam required for anyone operating a CMV across state lines or transporting hazardous materials. It’s conducted by a certified medical examiner and typically includes:
Vision and hearing tests
Blood pressure and pulse rate
Urinalysis (for protein, glucose, and signs of underlying conditions)
Review of your medical history
Physical exam covering heart, lungs, spine, joints, and neurological functions
The goal? To ensure you're medically qualified to handle the responsibilities of commercial driving.
How to Prepare for a DOT Physical
Here are practical tips to help you pass your exam without hassle:
1. Know What Medications You Take
Bring a list of all current medications, dosages, and the name of the prescribing doctor. Some medications can affect your ability to drive, so transparency is key. If you’re taking medication for diabetes, high blood pressure, or mental health, bring documentation showing that your condition is well-managed.
2. Get a Good Night’s Sleep
Sleep impacts your blood pressure and overall alertness. Being well-rested can prevent false positives on things like high blood pressure or irregular heart rate.
3. Watch Your Diet the Week Before
Avoid salty, fatty, and high-sugar foods in the days leading up to your exam. These can impact your blood pressure, cholesterol, and urinalysis results. Eat clean: opt for fruits, vegetables, lean proteins, and plenty of water.
4. Stay Hydrated — But Not Overhydrated
Drink enough water before your test to provide a urine sample, but avoid chugging large amounts right before the exam, as that can dilute your sample or affect blood pressure.
5. Limit Stimulants
Cut back on caffeine, energy drinks, and nicotine, especially on the day of your exam. These can spike your blood pressure or cause abnormal heart rate readings.
6. Bring Required Documents
Make sure to bring:
A valid driver’s license
Your current medical card (if renewing)
Glasses or contacts if you wear them
Hearing aids (if prescribed)
Any medical records or waivers you might need
7. Manage Chronic Conditions
If you have a chronic condition like diabetes, high blood pressure, or sleep apnea:
Bring proof of treatment and control (e.g., recent A1C or blood pressure logs)
For CPAP users, bring usage logs from the past 30 days
Talk to your healthcare provider ahead of time if adjustments to medications are needed
