Braking distance — Mississippi Permit Test
Braking distance on the Mississippi permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Stopping distances grow drastically when the weather is bad, the road is slick, or you are tired or intoxicated.
The chart shows a best case, and a wet road or a sleepy driver needs far more room than that.
If the weather is bad, the road is slick, or if you are tired or intoxicated, then the distances will be drastically different.
Total stopping distance includes the thinking distance you travel before you put on the brakes, plus the distance from braking to stop.
Your car keeps rolling while your brain sees the problem, so the stop starts later than you think.
The yellow segments show the distance required for thinking prior to activation of brakes.
The braking chart assumes ideal conditions: good tires, good brakes, and dry pavement.
Bald tires or worn brakes add distance the chart does not show.
The braking distances shown here assume ideal conditions: good tires, good brakes, and dry pavement.
On the test
What happens to stopping distances when the road is slick or you are tired?
They become drastically different. The chart shows a best case, and a wet road or a sleepy driver needs far more room than that. Mississippi Driver's License Manual, p.44: “If the weather is bad, the road is slick, or if you are tired or intoxicated, then the distances will be drastically different.”
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.
