Following distance — Mississippi Permit Test
Following distance on the Mississippi permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When following another vehicle, leave at least one car length for every 10 mph of speed.
If the car ahead stops short, that space is the only time you have to slow down or stop.
When you are following another vehicle, allow at least one car length between you for every ten miles per hour of speed.
At 30 mph, leave at least three car lengths between you and the vehicle ahead.
Three lengths sounds like a lot in town, but it is what a sudden stop at that speed needs.
@ 30 MPH leave at least THREE car lengths
Following too closely is dangerous and is the main cause of rear-end collisions.
A tailgater has no room to stop, so any quick stop ahead ends with a crash.
Following too closely to another vehicle is dangerous and the main cause of rear-end collisions.
Keep enough distance so that you can see around the vehicle ahead of you.
Hanging on a bumper hides the road ahead, so you learn of trouble only when the car in front brakes.
It is also important to maintain distance so that you can see around the vehicle ahead of you.
When you follow a large truck or bus, allow yourself even more room.
A big truck blocks your whole view of the road, and you cannot see what it is about to stop for.
When you follow a large truck or bus, allow yourself even more room.
In a motorcade such as a funeral procession, leave enough space between you and the next car so other vehicles can safely pull into those spaces.
A line of cars bumper to bumper leaves no gap, and a driver who must cut in has nowhere to go.
If you are taking part in a motorcade, such as a funeral procession, allow enough space between you and the next car so that other vehicles may safely pull into those spaces.
On the test
How much space should you leave behind the car ahead?
1 car length for every 10 mph. If the car ahead stops short, that space is the only time you have to slow down or stop. Mississippi Driver's License Manual, p.43: “When you are following another vehicle, allow at least one car length between you for every ten miles per hour of speed.”
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.
