Rain and wet roads — Mississippi Permit Test
Rain and wet roads on the Mississippi permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The opening minutes of rain or drizzle are the slickest and most dangerous; slow down when rain begins to fall.
Drivers often wait for heavy rain to slow down, but the road is most slippery before that.
the opening minutes of rain or drizzle are actually the slickest and most dangerous.
The first water to hit the road loosens dirt and grease, which forms a slick film on the road.
Knowing where the slick film comes from tells you why a light drizzle can be so risky.
The first water to hit the road loosens accumulated dirt and grease.
Most automobile skids are caused by driving too fast for the weather and road conditions.
Tires lose grip fast on a wet road, and speed takes away the room you need to recover.

On the test
When is a road most slick during a rain?
In the first minutes of rain. Drivers often wait for heavy rain to slow down, but the road is most slippery before that. Mississippi Driver's License Manual, p.65: “the opening minutes of rain or drizzle are actually the slickest and most dangerous.”
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.
