If a driver has at least one eye that satisfies the vision standard (acuity, field of vision, color), the ME should inform the driver of the Federal Vision Exemption program. With a federal vision exemption, the driver can operate a CMV in interstate commerce. This exemption may take 6 months to acquire.
Required use of corrective lenses should be marked in three places: Pages 2 and 3 on the Exam Report Form, and on the Medical Examiner’s Certificate.
The driver must meet the standard in both eyes to be certified unless they have an exemption.
