Headlights — New Hampshire Permit Test
Headlights 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
New Hampshire law requires every motor vehicle driven from 1/2 hour after sunset to 1/2 hour before sunrise to display at least 2 lighted lamps on the front.
The half-hour either side covers the part of dusk when a driver can still see but cannot be seen.

Headlights must also be displayed whenever rain, snow or fog interferes with the view of the road so that persons and vehicles are not clearly discernible at 1000 feet.
The rule is written as a distance rather than a weather type, so a driver can judge it out of the windshield.
not clearly discernible at a distance of 1000 feet ahead
One suitable lighted lamp on the front of a motorcycle is sufficient.
A motorcycle is too narrow to carry two lamps, so the law asks for the one it can.
one suitable lighted lamp on the front of a motorcycle shall be sufficient.
On the test
When must headlights be displayed under New Hampshire law?
From half an hour after sunset to half an hour before sunrise. The half-hour either side covers the part of dusk when a driver can still see but cannot be seen. New Hampshire Driver's Manual, p.15: “New Hampshire law requires every motor vehicle driven during the period from 1/2 hour after sunset to 1/2 hour before sunrise”
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.
