DOT Physical Vision Requirements: 20/40 Acuity, MCSA-5871, and the Alternative Standard in Charlotte, NC
The Traditional 20/40 Vision Standard
To pass the DOT physical without needing any special exemptions or alternative standard forms, you must meet the following minimum requirements in both the left and right eyes, with or without corrective lenses:
Minimum Vision Requirements:
- Distant Acuity: At least 20/40 in the right eye.
- Distant Acuity: At least 20/40 in the left eye.
- Distant Acuity: At least 20/40 when using both eyes together.
- Field of Vision: At least 70 degrees of horizontal peripheral vision in each eye.
- Color Recognition: Ability to recognize the colors of standard traffic signals (red, green, and amber).
Corrective Lenses and Refractive Surgery
- Contact Lenses/Glasses: You are permitted to wear contact lenses or glasses during the vision test, provided you are comfortable wearing them while driving.
- Laser Eye Surgery: Provided you meet the vision requirements, you should have no problem passing the exam.
- Monovision Disqualification: The use of contact lenses where one eye is corrected for distant visual acuity and the other for near vision (monovision) is not acceptable for commercial driving.
The Alternative Vision Standard (MCSA-5871)
Effective March 22, 2022, the FMCSA introduced the Alternative Vision Standard. This new process replaces the old, complex Federal Vision Exemption program and simplifies the certification process for drivers who do not meet the traditional standard, typically those with monocular vision (legally blind in one eye).
Key Requirements for the Alternative Standard
If you cannot meet the 20/40 requirement in both eyes, you may still qualify if you meet the following criteria in your better eye:
| Factor | Alternative Standard Requirement | Required Documentation |
|---|---|---|
| Better Eye Vision | At least 20/40 (Snellen) with or without corrective lenses. | You must submit a completed Vision Evaluation Report, Form MCSA-5871, signed by an Ophthalmologist or Optometrist. |
| Field of Vision | At least 70 degrees in the horizontal meridian in the better eye. | |
| Color Recognition | Ability to recognize the colors of standard red, green, and amber traffic signals. | |
| Stability | The vision deficiency must be stable, and the driver must have had sufficient time to adapt and compensate for it. |
Monocular Vision and Federal Certification
If you have monocular vision (e.g., legally blind in one eye from an injury) and meet the requirements of the Alternative Standard above, you are eligible for an interstate medical card. This new standard eliminates the need for the previous, lengthy waiver program.
Disqualifying Vision Conditions
Beyond not meeting the visual acuity numbers, certain vision conditions are immediately disqualifying because they pose an unpredictable risk to safe driving:
- Diplopia (Double Vision): Cannot be safely managed by an interstate driver.
- Telescopic Lenses: The use of telescopic lenses for driving a CMV is not acceptable under FMCSA rules.
- Progressive/Unstable Eye Disease: Any eye condition (like uncontrolled glaucoma or severe diabetic retinopathy) that results in fluctuating vision or an inability to obtain a stable acuity reading.
