On the test

What visual acuity must you have with both eyes to meet Wyoming's vision standard?

20/40. A driver who cannot read a sign until it is close has no time left to react to it. Wyoming Rules of the Road Driver License Manual, p.8: “A person must have 20/40 acuity with both eyes, either with or without glasses, and a combined horizontal field vision of at least 120 degrees to meet Wyoming vision standards for operating a motor 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.
