Vision requirements — Kentucky Permit Test

Vision requirements on the Kentucky permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Kentucky's visual requirements for driving are visual acuity of at least 20/60 or better in at least one eye.

One good eye can meet the standard. Two poor ones cannot.

In Kentucky, visual requirements for driving require an individual to have visual acuity of at least 20/60 or better in at least one eye.

Kentucky Driver Manual, p.20

A Kentucky driver's horizontal field of vision must be at least 35 degrees to both the left and the right.

Seeing straight ahead is not enough. A driver has to catch what comes from the side.

The driver’s horizontal field of vision must be at least 35 degrees to both the left and the right

Kentucky Driver Manual, p.20

A Kentucky driver's vertical field of vision must be at least 25 degrees above and below fixation.

The vertical field is what catches a signal overhead and a child in front of the hood.

The driver’s horizontal field of vision must be at least 35 degrees to both the left and the right, and their vertical field of vision must be at least 25 degrees above and below fixation.

Kentucky Driver Manual, p.20

The Kentucky Bioptic Driving Program requires distance visual acuity of 20/200 or better with corrective lenses in the better eye.

That is the floor for the bioptic route, and it is far below what an ordinary license needs.

Distance visual acuity of 20/200 or better with corrective lenses in the applicant’s better eye.

Kentucky Driver Manual, p.20

The Kentucky Bioptic Driving Program requires distance visual acuity of 20/60 or better using the bioptic telescopic device.

The telescope has to bring the driver back to the ordinary standard before they are allowed on the road.

Distance visual acuity of 20/60 or better using a bioptic telescopic device.

Kentucky Driver Manual, p.20

The Kentucky Bioptic Driving Program requires a visual field of 120 degrees horizontally and 80 degrees vertically in the better eye.

A narrow field hides everything approaching from the side, which no telescope can fix.

On the test

What is Kentucky's minimum visual acuity for driving?

20/60 or better in at least one eye. One good eye can meet the standard. Two poor ones cannot. Kentucky Driver Manual, p.20: “In Kentucky, visual requirements for driving require an individual to have visual acuity of at least 20/60 or better in at least one eye.”

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
