Stay away from caffeine, energy drinks, and nicotine at least 2–3 hours before your appointment, as these can raise your blood pressure and heart rate.
Drinking water can help make the urinalysis portion go more smoothly. Avoid sugary drinks or high-sodium foods beforehand.

Failing a DOT physical doesn’t automatically mean the end of your driving career. In many cases, you may be given a temporary medical disqualification while you manage or treat a health condition. Once it’s under control, you can retake the exam.
Some drivers may qualify for an exemption or a short-term medical card (valid for 3 to 12 months), depending on their situation and the discretion of the medical examiner.
In general, DOT physicals are required every 24 months. However, if you have a condition that needs monitoring (like hypertension), you may be required to complete them more frequently, sometimes annually or even every 3 to 6 months.
Q1: How long does a DOT physical take?
The exam typically takes 30 to 45 minutes. If additional documentation or testing is needed, it might take a bit longer.
Q2: What happens if I take medication?
Taking medication doesn’t disqualify you automatically. Bring a list of medications and ensure the medical examiner is aware of any prescriptions. Certain medications may require additional clearance.
Q3: Can I wear glasses or contact lenses during the vision test?
Yes, and you should bring them. Your certificate may include a note that corrective lenses are required while driving.
Q4: Can I go to any doctor for a DOT physical?
No. The exam must be conducted by a medical examiner certified by the FMCSA. You can find certified providers on the FMCSA National Registry website.
Q5: Do I need to fast before a DOT physical?
Not usually. However, if your employer requests a blood test for cholesterol or glucose, fasting may be required. Confirm this in advance.
A DOT physical is a necessary step for numerous employment openings in the transportation and logistics industry. While it may feel complex, the process is manageable with the right medication. By understanding what to anticipate and following simple guidelines like managing health conditions, staying doused , and bringing the necessary paperwork you can walk into your appointment confidently.
