Headlights in low visibility — Arizona Permit Test
Headlights in low visibility on the Arizona permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When sun glare, rain, dust or any other condition may keep your vehicle from being clearly seen, turn on your headlights on low beam.
Other drivers cannot avoid a car they cannot see. Lights make you visible in daylight glare, rain and dust.
When there is sun glare, rain, dust or any other condition where your vehicle may not be clearly visible to other drivers, turn on your headlights on low beam.
On rural roads, your headlights help drivers who may consider passing in your lane see that you are approaching.
A driver looking to pass may pull out into your lane if your car blends into the road. Your lights warn them you are coming.

On the test
In rain, dust or sun glare during the day, what should you do with your headlights?
Turn them on low beam. Other drivers cannot avoid a car they cannot see. Lights make you visible in daylight glare, rain and dust. Arizona Driver License Manual and Customer Service Guide, p.57: “When there is sun glare, rain, dust or any other condition where your vehicle may not be clearly visible to other drivers, turn on your headlights on low beam.”
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.
