Frequently Asked Questions
A DOT physical exam evaluates vision (20/40 or better each eye), hearing (forced whisper at 5 feet), blood pressure (below 140/90 for 2-year certification), urinalysis (for glucose and protein, not drug testing), overall physical examination including heart, lungs, neurological function, and musculoskeletal system. The examiner also reviews your health history for conditions like epilepsy, diabetes, cardiovascular disease, and sleep disorders. The exam must be performed by a certified medical examiner on the FMCSA National Registry.
To receive a 2-year DOT medical certificate, your blood pressure must be below 140/90 mmHg. Readings between 140-159 systolic or 90-99 diastolic allow 1-year certification. Readings of 160-179 systolic or 100-109 diastolic may qualify for a one-time 1-year certificate with treatment required. Readings at or above 180 systolic or 110 diastolic are disqualifying until blood pressure is reduced through treatment. You can use medication to control blood pressure and still pass.
Yes, in most cases. Drivers with diabetes controlled by diet, exercise, or oral medications can generally pass the DOT physical with documentation of stable blood sugar control. Insulin-dependent drivers must apply for a Federal Diabetes Exemption through FMCSA, which requires an endocrinologist evaluation, documented A1C history, and evidence of stable glucose management. The exemption must be renewed annually and requires self-monitoring of blood glucose levels.
A DOT medical certificate is valid for up to 2 years for drivers who meet all health standards. However, the certification period may be shortened to 1 year or less if the medical examiner identifies conditions requiring monitoring, such as elevated blood pressure, treated diabetes, or other health concerns. The examiner has discretion to set the certification period based on individual health factors.
DOT standards require distant visual acuity of at least 20/40 (Snellen) in each eye, with or without corrective lenses. You must also have a field of vision of at least 70 degrees in the horizontal meridian in each eye. If you wear corrective lenses to meet the standard, you must wear them while driving. Monocular vision (loss of one eye) requires a Federal Vision Exemption, which involves a road test and documented adjustment period.
The DOT physical itself does not include a drug test. The urinalysis performed during the physical checks for glucose (diabetes indicator) and protein (kidney function), not drugs. However, DOT-regulated employers are required to conduct separate pre-employment, random, post-accident, and reasonable suspicion drug and alcohol testing under 49 CFR Part 40. These are separate from the physical exam and follow strict chain-of-custody and testing procedures.
There is no specific weight or BMI limit for DOT physicals. However, drivers with a BMI of 35 or higher may be referred for sleep apnea screening, especially with a neck circumference over 17 inches (men) or 15.5 inches (women) and symptoms like excessive daytime sleepiness. If sleep apnea is diagnosed, treatment with CPAP and documented compliance is required before certification. Being overweight alone does not disqualify you.
Commercial drivers must have a valid DOT medical certificate at all times while operating CMVs in interstate commerce. The maximum certification period is 2 years, so most drivers undergo physicals every 2 years. Drivers with certain health conditions (hypertension, treated diabetes, cardiovascular disease) may be certified for shorter periods, requiring annual or semi-annual examinations. Always schedule your renewal before your current certificate expires.
Automatic disqualifiers include uncontrolled epilepsy or seizure disorders (seizure-free for 8+ years without medication may apply for exemption), vision worse than 20/40 without correction, hearing loss beyond DOT limits, blood pressure at or above 180/110, current use of Schedule I drugs, alcoholism, and certain cardiovascular conditions. Insulin-dependent diabetes and monocular vision are not automatic disqualifiers but require Federal Exemptions. Many conditions that initially appear disqualifying can be addressed with treatment and proper documentation.
What Is the DOT Physical Calculator?
The DOT physical calculator is a free screening tool that evaluates whether your current health metrics meet the Federal Motor Carrier Safety Administration (FMCSA) standards required for a Commercial Driver's License (CDL) medical certificate. It checks blood pressure, BMI, vision acuity, hearing, and diabetes status against the exact thresholds set out in 49 CFR Part 391.41 — the federal regulation governing driver fitness.
It's built for CDL applicants running their first DOT physical, renewal drivers who want to know if a borderline blood pressure reading will cost them their 2-year card, and fleet managers doing pre-exam wellness checks across a driver pool. Owner-operators use it to plan ahead before booking with a National Registry of Certified Medical Examiners (NRCME) examiner.
This isn't a replacement for an actual physical — only a licensed medical examiner can issue a Medical Examiner's Certificate. But it tells you exactly what to expect before you walk in the door. Learn more about how we built this tool on our About page.

Every result is derived from FMCSA regulations — here's the exact logic behind each metric.
CDL Medical Exam Guide: What You Need to Know
What DOT Medical Examiners Look For
A DOT physical isn't just a blood pressure check. NRCME-certified examiners go through a structured checklist covering cardiovascular health, vision, hearing, musculoskeletal function, neurological status, and mental health. They'll ask about your history of heart attacks, strokes, seizures, and any current medications. Everything gets documented on MCSA-5875, the Federal Motor Carrier Medical Examination Report form.
Blood pressure and BMI draw the most questions, but examiners pay close attention to sleep apnea risk — especially for drivers who report snoring, fatigue, or morning headaches. Sleep apnea is the fastest-growing reason for conditional certificates in the commercial trucking industry, according to the FMCSA's Large Truck Crash Causation Study data. Our DOT physical preparation guide walks through how to get ahead of these common roadblocks.
Certification Periods: 2-Year, 1-Year, and 90-Day
Most drivers with healthy vitals receive a 2-year Medical Examiner's Certificate. Drivers with Stage 1 hypertension (140–159 / 90–99), treated conditions requiring monitoring, or certain vision waivers may receive a 1-year certificate. Stage 2 hypertension or conditions still under active treatment often result in a 90-day certificate — a temporary clearance while you stabilize. The examiner can also issue a shorter certificate at their discretion for any health concern they want to monitor closely.

How to Prepare for a DOT Physical
The single most effective thing you can do before a DOT physical is take your blood pressure seriously in the weeks leading up to it. If you know yours runs high, start tracking it daily — many drivers have undiagnosed hypertension that only surfaces when an exam is on the line. A 30-day log showing readings below 140/90 gives your examiner documented context if your exam-day number is borderline.
Also bring: your current medication list (prescription and OTC), glasses or contacts, your hearing aid if you wear one, and any relevant specialist letters (cardiology, endocrinology). Our full preparation guide covers everything to bring and do in the 30 days before your exam.
When to See Your Doctor Before the Exam
If this calculator flags any concern — elevated BP, high BMI, vision close to threshold — schedule a primary care visit at least 3–4 weeks before your DOT exam date. That window gives you time to start medication, get a referral, or document compliance. Walking into your DOT exam with an untreated Stage 2 BP of 162/102 when you could have brought it to 144/88 with treatment is a costly mistake that delays your certification by 90 days.
Drivers with diabetes, heart conditions, or sleep apnea should also check our disqualifying conditions guide before their exam.
Who Should Use This Calculator?
This tool is most useful when you have a reason to think about your DOT physical results before the actual exam. Here's who gets the most out of it:
- First-time CDL applicants who have never been through a DOT physical and want to understand what the examiner will check before their appointment.
- Renewal drivers whose blood pressure or weight has changed since their last exam and want to know if they're still on track for a 2-year card.
- Owner-operators managing their own health without company HR support, who need to self-screen before booking an NRCME examiner.
- Fleet safety managers running voluntary pre-exam wellness checks across a group of drivers ahead of scheduled renewals.
- Drivers returning from medical leave who want to understand whether their current numbers will support return-to-duty certification.
You don't need to be a healthcare professional to use this calculator. If you can read the numbers off a BP cuff and a bathroom scale, you have everything you need. Try the calculator now or explore our DOT health guides to go deeper on any of the topics above.
