Seat belt use — South Dakota Permit Test

Seat belt use on the South Dakota permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

In South Dakota, it is illegal to drive or to be a front-seat passenger without wearing a seat belt.

An unbelted body keeps flying forward in a crash until the windshield or dashboard stops it.

In South Dakota, it is illegal to drive or to be a front-seat passenger without wearing seatbelts.
South Dakota Driver License Manual, p.25

The shoulder harness is worn across the shoulder and chest with little or no slack, never under the arm or behind the back.

A harness tucked under the arm crushes the ribs and organs in a crash.

The shoulder harness should not be worn under the arm or behind the back.

The lap belt should be snug and lie low across your hips; otherwise you could slide out of it in a crash.

A loose lap belt riding on the stomach lets you slide out underneath it in a crash.

The lap belt should be adjusted so that it is snug and lies low across your hips after fastening.
South Dakota Driver License Manual, p.25

Wear seat belts even with air bags: air bags do not protect you if you are hit from the side or rear or if the vehicle rolls over.

In a rollover an air bag does nothing to stop you being thrown out of the car.

While air bags are good protection against hitting the steering wheel, dashboard, or windshield, they do not protect you if you are hit from the side or rear or if the vehicle rolls over.

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.
