On the test
Who must wear a seat belt in Mississippi?
The driver and all passengers. In a crash, a loose rider in the back can be thrown forward into the people up front. Mississippi Driver's License Manual, p.64: “Drivers and all passengers of motor vehicles shall wear a properly fastened seat belt, regardless of whether the passenger is in the front seat or back seat of the vehicle.”
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.
