Examining FMCSA Vision Standard for CMV Drivers and Waiver Program

The aim of this research is to review the current visual requirements, concentrating on the requirements for visual acuity and visual fields, for CMV drivers and consider the limitations. The current standard requires drivers to have: • A distant visual acuity of at least 20/40 (Snellen) in each eye without corrective lenses or visual acuity separately corrected to 20/40 (Snellen) or better with corrective lenses; • A distant binocular acuity of at least 20/40 (Snellen) in both eyes with or without corrective lenses; • A field of vision of at least 70 degrees in the horizontal Meridian in each eye; • The ability to recognize the colors of traffic signals and devices showing standard red, green, and amber. In this age of evidence-based standards, it is pertinent to justify the current visual acuity standards. Driving research is fraught with limitations associated with the multi-factorial nature of the task and the difficulties in accessing accurate crash data. Studies have only shown a weak link between visual acuity and crash rates. Additionally, this study will assess the proportion of people, particularly the aging CMV drivers, who fail to meet the current visual requirements.
