High low beams — Nevada Permit Test
High low beams on the Nevada permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Use high beams in open country at night, and change to low beams at least 500 feet before an oncoming vehicle.
High beams in an oncoming driver's eyes blind them, and they can drift across the line into you.
Change to low beams when you are at least 500 feet before any oncoming vehicles and 300 feet before any vehicle you are following.
Change to low beams when you are at least 300 feet behind a vehicle you are following.
High beams glare in the mirrors of the car ahead and dazzle its driver, who may brake or swerve.
Change to low beams when you are at least 500 feet before any oncoming vehicles and 300 feet before any vehicle you are following.

On the test
How far before an oncoming vehicle must you change to low beams?
At least 500 feet. High beams in an oncoming driver's eyes blind them, and they can drift across the line into you. Nevada Driver Handbook, p.56: “Change to low beams when you are at least 500 feet before any oncoming vehicles and 300 feet before any vehicle you are following.”
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.
