Vision and driving — New Hampshire Permit Test
Vision and driving on the New Hampshire permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Trouble identifying traffic and roadway conditions, spotting potential trouble and responding in time may be the result of poor visual acuity.
Slow reactions often turn out to be late seeing. The driver was not careless, they simply got the picture later than everyone else.
Having trouble identifying traffic and roadway conditions, spotting potential trouble and responding to problems in a timely manner, may be a result of poor vision acuity.
Because seeing well is so important to safe driving, drivers should have eye examinations regularly.
Eyesight fades slowly enough that nobody notices it going. A test catches what a driver cannot feel.

A driver who needs corrective lenses should avoid using dark or tinted corrective lenses at night.
Tinted glass takes light away from eyes that already have less of it after dark, so it costs the driver exactly what they need most.

On the test
What may be behind a driver who spots trouble late?
Poor visual acuity. Slow reactions often turn out to be late seeing. The driver was not careless, they simply got the picture later than everyone else. New Hampshire Driver's Manual, p.7: “Having trouble identifying traffic and roadway conditions, spotting potential trouble and responding to problems in a timely manner, may be a result of poor vision acuity.”
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.
