The minimum visual acuity requirement for commercial drivers is 20/40. This standard ensures that drivers have sufficient vision to safely operate commercial vehicles, which can be larger and more difficult to control than standard vehicles. Having a visual acuity of 20/40 means that a driver can see at 20 feet what a person with normal vision can see at 40 feet, indicating a need for adequate vision to react to road hazards, read road signs, and maintain safe vehicle operation.

The standard is in place to minimize the risk of accidents caused by impaired vision, reflecting the importance of good sight for driving safety. Drivers who do not meet this requirement may need corrective lenses or further assessment to ensure they can safely fulfill their driving duties.
