Seat belts — Idaho Permit Test
Seat belts on the Idaho permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Idaho law requires all occupants to wear safety belts or shoulder straps when riding in a motor vehicle the factory fitted with them.
It applies to everyone in the car, not just the driver, and a loose passenger in a crash hits whoever is in front of them.

NHTSA studies show that safety belts, when worn, reduce your chances of serious injury in a crash by 50%.
Half is the figure. It is the single largest difference a driver can make in the second before an impact.

Safety belts are 60 to 70% effective in preventing fatalities in auto crashes.
The range is wide because crashes are, but the lowest figure in it is still most of the deaths prevented.

Safety belts also help a driver keep control of the car on winding or rough roads and when avoiding a collision.
A driver thrown sideways in their seat is a driver whose hands have moved on the wheel without meaning to.

On the test
Who must wear a safety belt in an Idaho vehicle fitted with them?
All occupants. It applies to everyone in the car, not just the driver, and a loose passenger in a crash hits whoever is in front of them.

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.
