As of January 21, 2022 the Federal Motor Carrier Safety Administration (FMCSA) has eased the requirements for passing Department of Transportation (DOT) commercial driver’s license (CDL) exams for applicants with vision in only one eye (monovision). In the past, drivers could meet requirements only with a waiver and documentation from an ophthalmologist. Under the new requirements, all other vision requirements must still be met. These requirements for the “better eye” include at least 20/40 vision with or without corrective lenses, at least 70 degrees horizontal field of vision, acceptable color vision, and no evidence of instability in their visual health. For what it’s worth, data has not shown that collision rates are any higher in drivers with monovision compared to drivers in general.
