DOT Vision Standards for Commercial Drivers
- At least 20/40 vision in each eye and with both eyes together, with or without correction
- At least a 70-degree horizontal field of vision in each eye
- The ability to recognize the colors of traffic signals: red, green, and amber
Drivers who don't meet the standard in one eye may qualify under the alternative vision standard. It requires at least 20/40 vision and a 70-degree horizontal field in the better eye, a stable condition, and a vision evaluation by an optometrist or ophthalmologist.
