What is the minimal acceptable visual acuity for driving in most states?

  1. 20/20

  2. 20/30

  3. 20/40

  4. 20/50

The correct answer is: 20/40

The minimal acceptable visual acuity for driving in most states is 20/40. This level of visual acuity means that a person can see at 20 feet what a person with normal vision can see at 40 feet. Having a visual acuity of 20/40 ensures that the driver has sufficient vision to be able to see road signs, traffic signals, and other vehicles on the road clearly to drive safely.
