Vision limits — Wyoming Permit Test

Vision limits on the Wyoming permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Drivers with poor side vision must look to the sides by moving their head as well as their eyes, and look over their shoulder when changing lanes.

Eyes alone cannot reach far enough to the side, so a car beside you can be missed.

Drivers with POOR SIDE VISION must look to the sides by moving their head as well as their eyes.

Wyoming Rules of the Road Driver License Manual, p.87

Drivers with poor distance judgment must allow more following distance, and more distance when deciding to pass.

If you cannot tell how far away an oncoming car is, you need a bigger gap to be safe.

They also have to allow more distance when deciding to pass.

Wyoming Rules of the Road Driver License Manual, p.88

Drivers with poor night vision should limit their driving to slower speeds on well-lighted streets, or to daytime driving only.

Driving much slower than traffic on a dark highway is dangerous too, so lit streets or daylight are safer.

These persons should limit their driving to slower speeds on well-lighted streets or to daytime driving only.

Wyoming Rules of the Road Driver License Manual, p.88

If your eyes are slow to recover from bright lights, look to the right side of the road, away from the glare; the best solution is to drive only in daylight.

Looking into glare blinds you for seconds, and the edge of the road keeps you in your lane.

Looking to the right side of the road, away from the glare, can help.

On the test

How must a driver with poor side vision check to the sides?

By turning the head, not just the eyes. Eyes alone cannot reach far enough to the side, so a car beside you can be missed. Wyoming Rules of the Road Driver License Manual, p.87: “Drivers with POOR SIDE VISION must look to the sides by moving their head as well as their eyes.”

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.
