Wet pavement — Louisiana Permit Test
Wet pavement on the Louisiana permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Roads are most slippery right after rain begins, because the oil and grease have not yet washed away.
The first rain lifts oil off the road and floats it on top, so the road can feel like ice.
Road surfaces are most slippery immediately after the rain begins to fall.
In a skid, stay calm, ease off the gas, and steer where you want the car to go; avoid using the brakes.
Slamming the brakes in a skid locks the wheels and makes the slide worse. Easing off lets the tires grip again.
If you find yourself in a skid, remain calm, ease your foot off the gas, look and carefully steer in the direction you want the car to go.
On the test
When are road surfaces most slippery?
Right after the rain starts to fall. The first rain lifts oil off the road and floats it on top, so the road can feel like ice. Class D & E Driver's Guide, p.74: “Road surfaces are most slippery immediately after the rain begins to fall.”
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.
