Vision requirements — Utah Permit Test

Vision requirements on the Utah permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

To drive a Class D vehicle in Utah a driver needs 20/40 vision in at least one eye and a visual field of at least 90 degrees.

Reading a sign is only half of seeing. The field is what catches the child stepping off the curb beside you.

The guidelines require you to have 20/40 vision in at least one eye and a visual field of at least 90° to drive a Class D (regular) vehicle.

Utah Driver Handbook 2026-2027, p.21

A Utah driver older than 65 at the time of a license application must pass a vision test.

Eyesight fades slowly enough that nobody notices it themselves. The test is the only thing that catches it.

When visiting a field office or if you are older than 65 at the time of your driver license application, you will be required to pass a vision test.

Utah Driver Handbook 2026-2027, p.21

A Utah applicant who cannot pass the vision test is asked to take a Certificate of Visual Examination form to an ophthalmologist.

Failing the machine at the counter is not a verdict. An eye doctor gets to say what you can actually see.

If unable to pass a vision test you will be requested to take a Certificate of Visual Examination form (CVE) to an ophthalmologist.

Utah Driver Handbook 2026-2027, p.21

A completed Certificate of Visual Examination must be presented before a Utah license application can be accepted.

The form is not a formality to post later. Without it the application simply does not move.

A completed vision form (CVE) should indicate your visual acuity and must be presented before your application for a license can be accepted.

The most important sense a driver uses is vision, and it is impaired at a blood alcohol content of 0.02 for every driver.

Two hundredths is less than one drink for most people. Sight goes first, and it is what you were using to drive.

Vision is impacted at 0.02 blood alcohol content (BAC) for all drivers. The most important sense you use in driving is vision.

On the test

What visual acuity does Utah require in at least one eye for a Class D license?

20/40. Reading a sign is only half of seeing. The field is what catches the child stepping off the curb beside you. Utah Driver Handbook 2026-2027, p.21: “The guidelines require you to have 20/40 vision in at least one eye and a visual field of at least 90° to drive a Class D (regular) vehicle.”

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.

What it costs

  • One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.

  • Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
