Vehicle equipment — Mississippi Permit Test

Vehicle equipment on the Mississippi permit test — 15 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Your vehicle must have both a foot brake and a parking brake.

If the foot brake fails, the parking brake is the only way left to stop the car.

Your vehicle must have a foot brake AND a parking brake.

Mississippi Driver's License Manual, p.19

The foot brake must be strong enough to stop the vehicle within 30 feet at a speed of 20 mph.

Weak brakes add feet to every stop, and those feet are where a crash happens.

The foot brake must be strong enough to stop the vehicle within thirty feet at a speed of twenty miles per hour.

Mississippi Driver's License Manual, p.19

The parking brake must be strong enough to stop the vehicle within 55 feet at 20 mph.

A parking brake that cannot hold or stop the car is useless the day the main brakes give out.

The parking brake must be strong enough to stop the vehicle within fifty-five feet at twenty miles per hour.

Mississippi Driver's License Manual, p.19

Your vehicle must have a horn that can be heard 200 feet away.

A horn nobody can hear cannot warn a driver or walker who is about to step into your path.

Your vehicle must have a horn which can be heard two hundred feet away.

Mississippi Driver's License Manual, p.19

It is against the law to have any siren or exhaust or spark whistle on a vehicle; noise-making devices are illegal.

A siren on a private car confuses drivers who pull over for what they think is an ambulance.

It is against the law to have any siren or exhaust or spark whistle on a vehicle. Noise making devices are illegal.

Mississippi Driver's License Manual, p.19

Your vehicle must have 2 headlights (1 for a motorcycle) and at least 1 taillight.

A car with one headlight out can be mistaken for a motorcycle, and others misjudge its width.

Your vehicle must have two headlights [one for a motorcycle] and at least one taillight.

Mississippi Driver's License Manual, p.19

It is recommended that your headlights let you see a person 500 feet ahead at night in good weather.

Dim or aimed-low headlights leave you no time to stop for a person in the road.

It is recommended that with your headlights you should be able to see a person five hundred feet ahead under good weather conditions at night.

Mississippi Driver's License Manual, p.19

The taillight on your vehicle must be red and visible 500 feet behind you.

A driver behind you must know at once that they are looking at the back of a car.

The taillight on your vehicle must be red and must be visible five hundred feet behind you.

Mississippi Driver's License Manual, p.19

Besides 2 headlights, your vehicle may have no more than 1 spotlight and no more than 3 auxiliary lights.

Too many bright lamps blind other drivers and hide where your car really is.

In addition to two headlights, your vehicle may have no more than one spotlight and no more than three auxiliary lights.

Mississippi Driver's License Manual, p.19

It is against the law for a spotlight or auxiliary light to be red or blue.

Red and blue lights look like police or fire trucks, and drivers may pull over or panic.

Mississippi Driver's License Manual, p.19

At no time should you have more than 4 lights, not counting headlights, burning at once.

A car lit up like a stage blinds the drivers coming the other way.

At no time should you have more than four lights (not including headlights) burning at once.

Mississippi Driver's License Manual, p.19

Your muffler must be in good working order and operate constantly; no one may use a muffler cutout, bypass or similar device.

A cut-out muffler fills the street with noise and smoke that others must breathe and hear.

The muffler on your vehicle must be in good working order and must operate constantly to prevent excessive or unusual noise and annoying smoke.

Mississippi Driver's License Manual, p.19

Mississippi law does not require a rearview mirror, but having one is recommended.

Without a mirror you have to turn your head to see behind, and that takes your eyes off the road ahead.

Mississippi law does not require you to have a rearview mirror, but it is recommended for you to have one.

Mississippi Driver's License Manual, p.19

If you drive a truck whose body blocks your view of the road behind, you are required by law to have a side mirror.

A truck body hides the cars behind it, and the side mirror is the only way to see them.

(If you drive a truck with a body that blocks your view of the road behind, you are required by law to have a side mirror.)

Mississippi Driver's License Manual, p.19

Your tires must be properly inflated, have good tread, and be free of breaks, cuts and decay; your windshield wipers must work.

On the test

Which brakes must a vehicle have in Mississippi?

A foot brake and a parking brake. If the foot brake fails, the parking brake is the only way left to stop the car. Mississippi Driver's License Manual, p.19: “Your vehicle must have a foot brake AND a parking brake.”

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.
