DOT Physical Requirements for Truck Drivers: What to Expect

Roughly 30% of commercial truck drivers have hypertension, making blood pressure the number one reason drivers fail their DOT physical. But here's what most guides don't tell you: 70% of drivers who fail for blood pressure successfully recertify within 3 to 6 months after getting treatment. A failed DOT physical isn't the end. It's a speed bump.

The DOT physical requirements for truck drivers cause more anxiety than the driving test itself. Drivers worry about blood pressure, sleep apnea screening, vision standards, and whether their medications will disqualify them. Most of that anxiety comes from not knowing what to expect.

This guide covers everything: what the exam tests, what disqualifies you, the exact blood pressure numbers that determine your card duration, what happens if you fail, and how to prepare. We also cover DOT physical requirements for non-CDL box truck drivers, because most guides assume you're driving an 18-wheeler. If you're driving a 26-foot box truck in the Twin Cities, the box truck driver requirements are different, and this article covers them.

DOT Physical Exam: What to Expect

If you're wondering what does a DOT physical consist of, here's every component. The DOT physical exam takes 30 to 45 minutes and must be performed by a medical examiner listed on the FMCSA National Registry. Here's every component they test.

DOT Physical Vision Requirements

• Distant visual acuity: At least 20/40 in each eye separately AND 20/40 with both eyes together
• Field of vision: At least 70 degrees horizontal in each eye
• Color recognition: Must distinguish red, green, and amber (traffic signal colors)

Glasses and contact lenses are permitted during the test. You don't need 20/20 vision. The standard is 20/40, which most people with a current prescription meet without issue.

Hearing Test

• Forced whisper test: Must hear a forced whisper at 5 feet or more in the better ear
• OR audiometric test: Average hearing loss must not exceed 40 decibels at 500, 1,000, and 2,000 Hz

Hearing aids are permitted. If you wear them while driving, wear them during the test.

Blood Pressure

Blood pressure is measured at every DOT physical and determines how long your medical card is valid. This is the most critical number for most drivers. See the full breakdown in the next section.

Urinalysis

The urine sample tests for glucose (diabetes screening), protein (kidney function), blood (infections or kidney stones), and specific gravity (hydration level).

This is NOT a drug test. This is one of the most common misconceptions about the DOT physical. The urinalysis screens for medical conditions only. Per FMCSA rules, a urine sample collected for the physical exam cannot legally be used for drug testing. Drug tests are separate, and they're required at different points in the hiring process.

Physical Examination

The medical examiner checks:
- Heart and cardiovascular: Listening for murmurs, irregular rhythms, signs of heart disease
- Lungs and respiratory: Listening for abnormal breath sounds
- Abdomen: Checking for enlarged organs, masses, hernias
- Spine and musculoskeletal: Range of motion, tenderness, deformities
- Extremities: Limb function, grip strength, range of motion
- Neurological: Reflexes, coordination, balance, sensory function

Height and weight are recorded but there is no official BMI cutoff that automatically disqualifies you. However, a BMI over 40 triggers mandatory sleep apnea screening, and a BMI of 33 to 35 with additional risk factors (loud snoring, high blood pressure, neck circumference over 17 inches) may also prompt screening.

DOT Physical Blood Pressure Requirements

Blood pressure is the make-or-break number among all DOT physical requirements for truck drivers. Here are the exact DOT physical blood pressure requirements and how they affect your medical card duration.

Category	Systolic	Diastolic	Card Duration
Normal	Below 140	Below 90	2 years (full card)
Stage 1 Hypertension	140-159	90-99	1 year
Stage 2 Hypertension	160-179	100-109	3-month temporary (one-time)
Stage 3 Hypertension	180+	110+	Disqualified

If either number (systolic or diastolic) falls in a higher category, the higher category applies. A reading of 138/92 counts as Stage 1 because the diastolic is above 90.

What Happens at Each Stage

Stage 1 (140-159 / 90-99): You get a 1-year medical card instead of 2 years. No other restrictions. You'll need to recertify annually instead of every two years.

Stage 2 (160-179 / 100-109): You receive a one-time, 3-month temporary card. During those 3 months, you must get your blood pressure below 140/90 through medication or lifestyle changes. If you hit that target at your recheck, you receive a 1-year card. This temporary card is a one-time grace period. You cannot get a second one.

Stage 3 (180+ / 110+): Immediate disqualification. No card issued. You must lower your blood pressure to 140/90 or below, then return for recertification. Once controlled, you receive a 6-month card with biannual rechecks.

Tony had been driving a box truck for a food distributor in Shakopee for three years without any health concerns. At his routine DOT physical renewal, his blood pressure came back at 162/104, Stage 2. He'd been skipping his blood pressure medication for weeks. The examiner issued a 3-month temporary card and told him to see his doctor immediately. Tony started taking his medication consistently, cut his sodium intake, and started walking 30 minutes after his shift. At his 3-month recheck, he was at 134/86. He got his 1-year card and hasn't missed a dose since. "Losing the 2-year card was the wake-up call I needed," he says.

If you're preparing for a DOT physical and know your blood pressure runs high, see our tips section below for how to prepare.

DOT Physical Disqualifications: What Can Fail You

Understanding DOT physical disqualifications is critical for any driver preparing for the exam. Some conditions are absolute. Others are manageable with documentation.

Automatic Disqualifiers

These conditions disqualify you from certification without exception:

• Vision below standards: Cannot achieve 20/40 in each eye even with correction, or field of vision below 70 degrees
• Hearing below standards: Cannot hear forced whisper at 5 feet or fails audiometric test
• Epilepsy or seizure disorders: Any seizure or episode of loss of consciousness (exemption possible if seizure-free 8+ years)
• Stage 3 hypertension: Blood pressure at or above 180/110
• Implantable cardioverter defibrillator (ICD): Any driver with an ICD is permanently disqualified

Conditions Evaluated Case by Case

These don't automatically disqualify you but require documentation and may limit your card duration:

• Insulin-treated diabetes: Permitted since 2018. Requires Form MCSA-5870 from your treating clinician. Annual recertification.
• Sleep apnea: Must demonstrate CPAP compliance (4+ hours per night, 70% of nights). Bring 90+ days of CPAP data. Annual recertification.
• Heart conditions: Heart attack, bypass, angioplasty, arrhythmias. Requires cardiologist clearance.
• Pacemaker: Not automatically disqualifying with cardiologist documentation.
• Respiratory conditions: COPD, asthma. Evaluated by severity and control.
• Loss of a limb: May qualify with a Skills Performance Evaluation.

Medications That May Disqualify You

Always disqualifying:
- Methadone (no exceptions)
- Marijuana (including medical marijuana in legal states)
- Opioids (fentanyl, oxycodone, hydrocodone, morphine, codeine)
- Amphetamines (Adderall, Vyvanse) without proper documentation
- Schedule I controlled substances

Case by case:
- Benzodiazepines (Xanax, Valium)
- Anti-seizure medications
- Sedating antihistamines
- Sleep aids and muscle relaxants

If you take a prescription medication that might be flagged, get a clearance letter from your prescribing doctor before the exam. The letter should state that you can safely operate a commercial motor vehicle while taking the medication.

Do Non-CDL Box Truck Drivers Need a DOT Physical?

Yes, in most cases. This is one of the most commonly misunderstood DOT physical requirements for truck drivers.

Under federal regulations (49 CFR Part 391), any driver operating a commercial motor vehicle with a GVWR over 10,001 pounds in interstate commerce must pass a DOT physical. Since most box trucks exceed 10,001 pounds, this includes the majority of non-CDL box truck drivers.

When it's required: Your box truck weighs over 10,001 lbs GVWR and your route crosses state lines (interstate commerce).

When it's strongly recommended: Even for purely intrastate routes, many employers require a DOT physical as company policy. Insurance companies often mandate it regardless of federal requirements. In Minnesota, the state adopts FMCSA medical standards for both interstate and intrastate non-excepted commercial drivers.

The bottom line: if you're applying for box truck positions in the Twin Cities, plan on needing a DOT physical regardless of your CDL status.

DOT Medical Card Requirements: Cost, Location, and Process

Where to Get a DOT Physical

Only healthcare providers listed on the FMCSA National Registry of Certified Medical Examiners can perform DOT physicals. This includes MDs, DOs, physician assistants, advanced practice nurses, and chiropractors who are FMCSA-certified.

Search for certified examiners near you at the FMCSA National Registry website.

How Much Does a DOT Physical Cost?

Location Type	Typical Cost
Chiropractor offices	$60-$90
Urgent care clinics	$75-$150
Occupational medicine clinics (Concentra)	$100-$150
Primary care offices	$100-$200
Minnesota average	$60-$150

DOT physicals are usually not covered by health insurance. Many employers cover the cost for their drivers. If you're paying out of pocket, chiropractor offices and urgent care clinics in the Twin Cities tend to offer the lowest rates.

What to Bring

Required:
- Valid driver's license or photo ID
- Complete list of all medications (names, dosages, prescribing doctors)
- Glasses, contacts, or hearing aids you use while driving

If you have a condition:
- Diabetes: Blood sugar logs, most recent HbA1c results, Form MCSA-5870 (if insulin-treated)
- Sleep apnea: 90+ days of CPAP compliance data
- Heart conditions: Letter from cardiologist confirming safe to drive
- Vision deficiency: Form MCSA-5871 from ophthalmologist/optometrist

How Often Do You Need a DOT Physical?

• Standard: Every 2 years
• Stage 1 hypertension: Every 1 year
• Insulin-treated diabetes: Every 12 months
• Sleep apnea: Every 12 months
• Other monitored conditions: At examiner's discretion

2025 Electronic Certification Changes

As of June 23, 2025, the FMCSA's National Registry II system requires medical examiners to electronically submit exam results. Results are transmitted directly to state DMVs, which automatically update driver records. Drivers no longer need to manually submit paper medical certificates to state agencies or carry the physical card while driving (though keeping a copy is still recommended during the transition period through January 10, 2026).

How to Pass a DOT Physical: Preparation Tips

Understanding the DOT physical requirements for truck drivers is one thing. Preparing for the exam is another. Here's how to pass a DOT physical on your first try.

Blood Pressure Preparation (Start 2 to 4 Weeks Before)

Blood pressure is the number one reason drivers fail the DOT physical requirements for truck drivers. If you know yours runs high, start preparing early.

Weeks before the exam:
- Take all prescribed BP medications consistently. Do not skip doses.
- Reduce sodium intake significantly (cut processed foods, restaurant meals, and added salt)
- Exercise daily: 30 minutes of brisk walking minimum
- Drink 8+ glasses of water per day
- Get 7 to 8 hours of sleep consistently
- Eat potassium-rich foods: bananas, sweet potatoes, spinach

Day of the exam:
- No caffeine (coffee, tea, energy drinks, soda)
- No tobacco for at least 30 minutes before
- Arrive early to avoid rushing and stress
- Sit quietly for 5 to 10 minutes in the waiting room
- Practice slow, deep breathing
- Use the restroom before the test (a full bladder raises BP)
- Eat a light meal, nothing heavy, fatty, or salty

Vision Preparation

• Update your glasses or contacts prescription if it's been more than a year
• Bring your corrective lenses to the exam
• The standard is 20/40 per eye, not 20/20. Most people with a current prescription pass.

General Tips

• Disclose all medications honestly. Hiding medications can result in disqualification or fraud charges.
• Bring a typed list of every medication with drug names, dosages, and prescriber information.
• If you have a condition that requires specialist documentation, get those letters and forms completed before your appointment.
• Avoid alcohol for 24+ hours before the exam.
• Don't overhydrate (it can affect urinalysis specific gravity readings).

Megan was a warehouse associate in Brooklyn Park preparing for her first box truck driving job. She'd never had a DOT physical and was worried about the process. She scheduled her exam at an urgent care clinic a month before her planned application date, giving herself time to address any issues. Her vision was fine. Her blood pressure was 136/88, just under the Stage 1 threshold. She got the full 2-year card on her first try. "Getting it done early took the pressure off," she says. "I walked into my truck driver interview with the card in hand, and the hiring manager said that put me ahead of most applicants."

DOT Physical vs Drug Test: They're Not the Same Thing

This confusion comes up constantly. The DOT physical and the DOT drug test are completely separate requirements.

DOT physical: A medical fitness exam that checks whether you're physically capable of safely operating a commercial vehicle. Tests vision, hearing, blood pressure, and general health.

DOT drug test: A controlled substance screening that checks for illegal drug use. This is a separate urine collection, typically performed as a pre-employment test before your first shift.

The urinalysis during the DOT physical tests only for glucose, protein, blood, and specific gravity. It does not test for drugs. A urine sample collected during the physical cannot legally be used for drug testing.

For non-CDL box truck drivers, federal DOT drug testing regulations don't apply, though virtually every employer conducts pre-employment drug screening as company policy.

DOT Physical Requirements: Frequently Asked Questions

What does a DOT physical consist of?

A DOT physical includes vision testing (20/40 per eye), hearing testing (forced whisper at 5 feet), blood pressure measurement, urinalysis (glucose, protein, blood), and a full physical exam covering heart, lungs, spine, extremities, and neurological function. The exam takes 30 to 45 minutes and must be performed by an FMCSA-certified medical examiner.

How much does a DOT physical cost?

$60 to $200 depending on location. In Minnesota, expect $60 to $150. Chiropractor offices tend to be cheapest ($60-$90). Urgent care and occupational medicine clinics run $75 to $150. Most employers cover the cost for their drivers. Health insurance typically does not cover DOT physicals.

Can you fail a DOT physical for being overweight?

There is no BMI cutoff that automatically disqualifies you. However, a BMI over 40 triggers mandatory sleep apnea screening. If you're diagnosed with sleep apnea, you must demonstrate CPAP compliance (4+ hours per night, 70% of nights) to maintain certification.

What blood pressure is too high for a DOT physical?

Stage 3 hypertension (180/110 or higher) results in immediate disqualification. Stage 2 (160-179/100-109) gets a 3-month temporary card. Stage 1 (140-159/90-99) gets a 1-year card. Below 140/90 gets the full 2-year card.

Do non-CDL box truck drivers need a DOT physical?

Yes, if the vehicle's GVWR exceeds 10,001 lbs and you drive in interstate commerce. Most box trucks exceed 10,001 lbs. Many employers require a DOT physical for all commercial drivers regardless of CDL status or route type. In Minnesota, state rules mirror federal standards for both interstate and intrastate commercial drivers.

Does the DOT physical include a drug test?

No. The DOT physical and drug test are separate. The urinalysis during the physical tests for glucose, protein, and blood as medical screens. It does not test for drugs. Drug testing is performed separately, usually as a pre-employment requirement.

How long is a DOT medical card valid?

Up to 24 months (2 years) for drivers with no health concerns. Shorter durations are issued for monitored conditions: 1 year for Stage 1 hypertension or insulin-treated diabetes, and as short as 3 to 6 months for Stage 2/3 hypertension.

Get Your DOT Physical and Start Driving

The DOT physical requirements for truck drivers are straightforward once you know what to expect. Now that you understand every component of the DOT physical exam, what to expect, and how to prepare, the next step is simple. The exam takes under an hour, costs $60 to $150, and the vast majority of drivers pass on the first try. If blood pressure is a concern, start preparing 2 to 4 weeks ahead with medication compliance, reduced sodium, and daily exercise.

Get your DOT physical done before you start applying. Walking into an interview with a current medical card puts you ahead of most candidates and eliminates a hiring delay. For non-CDL box truck positions, it's one of the simplest steps in the process.
