Vision test — New Hampshire Permit Test
Vision test on the New Hampshire permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
An applicant must have a visual acuity of 20/40 vision in both eyes.
The standard is set where a driver can still read a sign in time to act on it rather than as it goes past the window.
Applicants must have a visual acuity of 20/40 vision in both eyes.
An applicant with sight in only one eye must have a visual acuity of 20/30.
One eye gives no depth from the second, so the state asks that the one eye see more sharply to make up part of the difference.
If an applicant has sight in only one eye, they must have a visual acuity of 20/30.
A driver who needed glasses or contact lenses to pass the vision test must wear them while driving, and the “B” restriction for corrective lenses is placed on the license.
The test was passed with the lenses on. Driving without them is driving on eyesight the state never approved.
the “B” restriction for corrective lenses will be placed on the applicant’s license.
An applicant who does not pass the vision test must supply an eye examination containing a doctor’s recommendation of visual capability before further license testing.
A failed vision test stops everything else, because there is no point testing the rules on somebody who cannot see the signs.

On the test
What visual acuity must an applicant have in both eyes?
20/40. The standard is set where a driver can still read a sign in time to act on it rather than as it goes past the window. New Hampshire Driver's Manual, p.2: “Applicants must have a visual acuity of 20/40 vision in both 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.
