Weather and sun glare — Arizona Permit Test
Weather and sun glare on the Arizona permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When weather reduces visibility and reaction time, the first rule is to slow down.
Rain, snow and dust hide hazards until they are close. Lower speed buys back the time the weather takes away.
The first rule is to slow down to make up for reduced visibility and reaction time.
Reduced visibility and traction problems often occur at the same time.
The same storm that hides the road also makes it slick, so you see a hazard late and then take longer to stop for it.
Reduced visibility and traction problems often occur at the same time.
Sun glare can be reduced by wearing sunglasses, keeping windows clean and using sun visors.
Low sun on a dirty windshield can white out the view of a stopped car or a person crossing. Cutting the glare keeps them visible.

On the test
What is the first rule when bad weather reduces visibility and reaction time?
Slow down your vehicle. Rain, snow and dust hide hazards until they are close. Lower speed buys back the time the weather takes away. Arizona Driver License Manual and Customer Service Guide, p.54: “The first rule is to slow down to make up for reduced visibility and reaction time.”
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.
