Inability to distinguish among traffic devices showing red, amber, and green colors
The color vision requirement is met by the ability to recognize and distinguish among red, amber, and green, the standard colors of traffic control signals and devices. True color perception is not required. A driver who lacks the ability to distinguish between red, amber, and green cannot be certified.
