Visual Standards

Pennsylvania, like most states, has created some basic legal requirements for the vision of its licensed drivers.  Here’s a basic overview of the laws in Pennsylvania.

VISUAL ACUITY

Visual acuity is basically how well you can see.  Perfect vision is considered 20/20, which means you can read something clearly at a distance of 20 feet.  20/40 means that you can read something clearly at 20 feet that someone with perfect vision can read clearly at 40 feet.

BASIC STANDARDS

Generally, a person must have a visual acuity of at least 20/100 combined and a horizontal field of view of at least 120° in order to be eligible for driving privileges in the Commonwealth of Pennsylvania.

A person must have visual acuity of 20/40 or better to drive without corrective lenses.  Corrective lenses that bring visual acuity to 20/40 or better, if needed, must be worn at all times while driving.

If vision can only be corrected to 20/60 or better, but not 20/40 or better, then the person may be eligible for a restricted license for daytime driving only.

A person with visual acuity of between 20/70 and 20/100 could be eligible for a restricted license prohibiting driving on freeways and highways.

A person with sight in only one eye can still meet the requirements to drive, provided the functional eye meets the visual acuity standards and the car is equipped with mirrors positioned so as to give the driver a view of the roadway of at least 200 feet to the rear.
