Vision Standard and the One-Year Card
Renee is 41 and has driven a Nebraska school bus for six years. At her DOT physical, her uncorrected vision is 20/100 right and 20/200 left. With glasses it is 20/40 right and 20/50 left. Her horizontal visual field is 75 degrees in each eye. The medical examiner writes 'meets vision standard with corrective lenses' and issues a one-year card. Renee’s route includes early-morning rural driving and a highway railroad crossing. She has no other medical conditions and takes no medications. She asks whether the 20/50 left eye is acceptable, whether she may drive without glasses when moving buses in the lot, and whether she must report the vision result to the DMV. Her self-certification is non-excepted interstate.
1. Does Renee meet the federal vision standard?
Read the worked answer
No, based on the corrected acuity given. The standard requires at least 20/40 in each eye, with or without corrective lenses, and a horizontal field of at least 70 degrees in each eye. Renee’s right eye meets 20/40, and her 75-degree fields meet the field requirement, but her left eye is only 20/50 with glasses. The medical examiner’s note that she 'meets' the standard is not consistent with those numbers. She needs further correction to 20/40 in the left eye or a valid vision exemption before she can be certified. A driver cannot rely on good vision in one eye to satisfy the other-eye requirement. The district should not dispatch her until the vision issue is resolved and the medical certificate accurately reflects her qualification.
2. May she drive without glasses when moving buses in the lot?
Read the worked answer
No. If her medical certificate or CDL carries a corrective-lenses restriction, she must wear the glasses whenever she operates the commercial motor vehicle, including yard moves and repositioning. A parking lot is still driving a school bus, and students or pedestrians may be present. The restriction is not limited to road routes. Driving without the required correction would violate the restriction and could also mean she does not meet the vision standard at the time of operation. The district should treat yard movement as a safety-sensitive driving task and enforce the restriction consistently.
3. What should happen with the medical certificate and the DMV record?
Read the worked answer
Renee should not drive on a certificate that appears to certify a vision result she does not meet. She should return to the examiner or a qualified vision specialist, obtain further correction or an exemption if eligible, and get a corrected medical certificate. Once she has a valid certificate, she must provide it to the DMV and to her employer so the self-certification record is current. Because she is non-excepted interstate, she must maintain the medical certificate continuously. The district should document the restriction, verify the certificate and any exemption, and keep her out of service until the discrepancy is resolved. She should not simply ignore the left-eye result because the examiner issued a one-year card.
