Question: 1 / 400

What minimum visual acuity is required to pass the interstate CMV driver vision exam?

20/50

20/30

20/40

The minimum visual acuity required to pass the interstate Commercial Motor Vehicle (CMV) driver vision exam is 20/40. This standard ensures that drivers can see and react to various road conditions, signs, and other vehicles adequately while operating a commercial vehicle. Achieving this level of visual acuity is crucial for safety, as it allows drivers to maintain awareness of their surroundings and make informed decisions on the road.

Drivers must adequately meet this standard with or without corrective lenses. If a driver's vision is not at least 20/40, it indicates that they may struggle to perceive important visual cues, which could potentially lead to dangerous situations. Thus, 20/40 is established as the baseline for visual acuity in the context of CMV operation to promote safety and efficacy in driving performance.
