Monthly vehicle checks — Louisiana Permit Test
Monthly vehicle checks on the Louisiana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Each month, check your license plate for readability and reflective properties.
Police and other drivers must be able to read your plate, even at night in their headlights.
Check condition of license plate for readability and reflective properties, and damage or scratches, which would affect the appearance of the plate.
Each month, check the windshield for cracks in the area the wipers sweep.
A crack right where you look through the glass blocks your view of the road ahead.
Check mirrors and windows for cracks and check windshield for cracks in the wiper operating area.
Each month, check that your brake lights and emergency flashers are working.
Drivers behind you rely on your brake lights to know you are stopping.
Ensure brake lights and emergency flashers are working.
Before checking under the hood, make sure the engine has cooled down and the parking brake is set.
A hot engine can burn you, and a car that rolls while you work under the hood can run you over.
Make sure your vehicle’s engine has cooled down before checking under the hood and ensure the parking brake is applied while making all suggested checks.
On the test
How often does the manual suggest checking your license plate for readability?
Every month. Police and other drivers must be able to read your plate, even at night in their headlights. Class D & E Driver's Guide, p.44: “Check condition of license plate for readability and reflective properties, and damage or scratches, which would affect the appearance of the plate.”
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.
