Weekly vehicle checks — Louisiana Permit Test
Weekly vehicle checks on the Louisiana permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You should always do a pre-trip inspection of your vehicle before driving.
A quick walk around and look over can find a flat tire or a leak before it causes trouble on the road.
You should always conduct a “pre-trip” inspection of your vehicle before driving.
Check weekly that tire pressure is within the range listed on the tire.
Tires that are low or too full grip the road poorly and wear out sooner.
Check tire pressure to ensure it is within the pressure range listed on the tire.
Tires need at least 1/16 of an inch of tread depth between all treads.
Worn-down tread cannot push water out of the way, so the tires slide on wet roads.
Ensure tires have adequate tread – at least 1/16 of an inch depth between all treads.
The weekly checks include making sure the oil level is within the operating range shown on the dipstick.
Too little oil lets engine parts grind together, and that can ruin the engine.
Make sure oil level is within the vehicle’s operating range listed on the dipstick.
The weekly checks include making sure the horn works properly.
The horn is how you warn others of danger fast, so it has to work when you need it.
Make sure the horn operates properly.
The weekly checks include inspecting seat belts for unusual wear or broken parts.
A frayed or broken belt may snap or fail to lock in a crash, just when you need it.
Inspect seat belts for unusual wear or malfunctioning parts.
On the test
What should you always do with your vehicle before you drive it?
A pre-trip inspection. A quick walk around and look over can find a flat tire or a leak before it causes trouble on the road. Class D & E Driver's Guide, p.44: “You should always conduct a “pre-trip” inspection of your vehicle before driving.”
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.

- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
