Sample questions

Six questions from the Mississippi bank, with the rule behind each answer

Sample 1 · Mississippi Cdl Classes Permits Testing And Driver Qualifications

For a Jackson fleet credential decision, a Mississippi road tractor pulls two trailers. The listed combination rating is 33,500 pounds, and the trailers together are rated above 10,000 pounds. What class of CDL is called for?

  1. For the credential review in Jackson: class A for a combination of at least 26,001 pounds with more than 10,000 pounds of towed GVWRCorrect
  2. For the credential review in Jackson: class B because multiple trailers are counted as part of one straight truck
  3. For the credential review in Jackson: class C because the combination has three vehicle units
  4. For the credential review in Jackson: no CDL because neither trailer individually weighs 26,001 pounds

Why: For the credential review in Jackson: class A for a combination of at least 26,001 pounds with more than 10,000 pounds of towed GVWR follows because class A covers a combination rated at least 26,001 pounds when the towed vehicle or vehicles have a gross vehicle weight rating above 10,000 pounds.

Sample 2 · Speed Space Hazards Weather And Railroad Crossings

As road conditions change near Jackson, in a convex mirror, a sedan seems distant enough for a lane change. Which perception error should make the truck driver wait and verify?

  1. For travel through Jackson: the mirror makes the sedan appear smaller and farther away than its actual positionCorrect
  2. For travel through Jackson: the mirror always makes following traffic appear closer than reality
  3. For travel through Jackson: convex glass removes every blind area and measures exact speed
  4. For travel through Jackson: the sedan's image cannot change size while it approaches

Why: For travel through Jackson: the mirror makes the sedan appear smaller and farther away than its actual position follows because mirror checks should be brief, and convex mirrors require judgment because they make objects appear smaller and farther away than they are.

Sample 3 · Cargo Inspection Weight Balance And Securement

While freight is arranged at a Jackson warehouse, a loader tells the driver, 'I secured it, so you have nothing to inspect.' Which responsibilities contradict that claim?

  1. For the shipment from Jackson: the driver must still address inspection, overload, balance, securement, visibility, and access to emergency equipmentCorrect
  2. For the shipment from Jackson: the driver is responsible only for signing the bill of lading
  3. For the shipment from Jackson: the loader assumes every safety duty until the cargo is delivered
  4. For the shipment from Jackson: a sealed door cancels all driver responsibility for load condition

Why: For the shipment from Jackson: the driver must still address inspection, overload, balance, securement, visibility, and access to emergency equipment follows because even when another person loads the vehicle, the driver remains responsible for inspection, overload and balance recognition, securement, clear visibility, and access to emergency equipment.

Sample 4 · Passenger Vehicle Inspection Loading And Operation

As passenger service is readied in Jackson, a bus operator receives a prior inspection report marked 'door defect.' Which documentation allows the operator to sign it?

  1. For the bus service in Jackson: a blank work order with no disposition of the listed defect
  2. For the bus service in Jackson: the route schedule alone, because departure time overrides the report
  3. For the bus service in Jackson: certification that the defect was repaired or did not require repairCorrect
  4. For the bus service in Jackson: a passenger's opinion that the door looks acceptable

Why: For the bus service in Jackson: certification that the defect was repaired or did not require repair follows because a bus driver signs the previous driver's inspection report only after listed defects have been certified as repaired or certified as not requiring repair.

Sample 5 · Combination Vehicle Control Coupling And Inspection

Before combination-vehicle dispatch from Jackson, a combination load is low at the rear but high and offset at the front. What loading objective should guide the correction?

  1. For the combination dispatched from Jackson: concentrate everything at one trailer corner for easier unloading
  2. For the combination dispatched from Jackson: leave the load and use a faster steering response in curves
  3. For the combination dispatched from Jackson: keep cargo low, near the center, and distributed rather than concentratedCorrect
  4. For the combination dispatched from Jackson: move the remaining weight high and to the same offset side

Why: For the combination dispatched from Jackson: keep cargo low, near the center, and distributed rather than concentrated follows because combination cargo should be kept low, centered, and distributed because a high or side-biased center of gravity increases rollover risk.

Sample 6 · Hazardous Materials And School Bus Safety

During regulated transportation duty in Jackson, a carrier asks a hazmat driver to take one poorly sealed package and fix it at the destination. What is the driver's proper role at pickup?

  1. For the regulated operation in Jackson: place the package by the driver's seat and remove all placards
  2. For the regulated operation in Jackson: carry it only at night because packaging rules apply in daylight
  3. For the regulated operation in Jackson: refuse the improperly prepared package and verify the shipment's required placards and papers before safe transportCorrect
  4. For the regulated operation in Jackson: accept it, conceal the defect, and discard the shipping paper

Why: For the regulated operation in Jackson: refuse the improperly prepared package and verify the shipment's required placards and papers before safe transport follows because the hazardous-material driver rejects leaking or improperly prepared packages, maintains required placards and papers, and transports the shipment safely after shipper and carrier checks.

What is on the test

The 10 topics the Mississippi CDL practice test covers

These are Mississippi's own topic areas, from mississippi cdl classes permits testing and driver qualifications to hazardous materials and school bus safety, each with 10 questions. Under each one are two questions from the bank, shown without their answers; the practice test explains every one of them.

  1. Mississippi Cdl Classes Permits Testing And Driver Qualifications10 questions

How to prepare

A study plan for the Mississippi CDL knowledge test

1

Find out where you stand

Take a Quick check of 25 in coaching mode. Read each explanation, including the ones you got right; it tells you the rule Mississippi tests, not just the answer.

2

Study the topics you missed

Your account's Study tab ranks the 10 topics by your results. Read that chapter of the Mississippi Commercial Driver's License Manual, then take another Quick check to confirm the gap has closed.

3

Rehearse the real thing

Take the Full challenge of 100 in exam mode. Aim for 80 percent or better twice in a row; at that point you are answering from the rules, not from memory of the questions.

Questions

Mississippi CDL practice test questions

Is this the official Mississippi CDL knowledge test?

No. DMV Exam Pass is an independent study service and is not affiliated with Mississippi Department of Public Safety, Driver Service Bureau. The questions are written in the style of the exam to prepare you for it; the official test is taken with the agency.

What does the Mississippi CDL practice test cover?

The 100 questions are spread evenly across 10 topics: Mississippi Cdl Classes Permits Testing And Driver Qualifications, Vehicle Inspection Control Visibility And Communication, Speed Space Hazards Weather And Railroad Crossings, Emergencies Abs Skids Crashes Fires And Driver Fitness, Cargo Inspection Weight Balance And Securement, Passenger Vehicle Inspection Loading And Operation, Air Brake Components Inspection And Use, Combination Vehicle Control Coupling And Inspection, Doubles Triples And Tank Vehicle Operation, and Hazardous Materials And School Bus Safety. Every test you take draws from all of them, so a weak area shows up quickly.

How many questions are in the practice test, and how long does it take?

The Mississippi bank holds 100 questions. A Quick check of 25 takes about ten minutes, a Practice run of 50 about twenty, and the Full challenge of 100 about forty. You can pause any time.

Are these the real questions from the Mississippi exam?

No. Nobody outside the agency has the real questions, and we do not use, claim, or advertise leaked or exact exam questions. These are independently written questions that test the same rules, so what you learn transfers to whatever the real test asks.

Which handbook should I study for the Mississippi CDL knowledge test?

The Mississippi Commercial Driver's License Manual (Version: March 2025), published by Mississippi Department of Public Safety, Driver Service Bureau. Every question here is written for it, and each explanation names the rule, so when you miss a question you know which chapter to read.

What is the difference between coaching mode and exam mode?

Coaching mode shows whether each answer was right, and why, before you move on; it is for learning. Exam mode holds the explanations and the correct choices until the end and still shows your running score; it is for checking readiness. Both draw from the same bank, and scoring happens on our servers, so no answer key is loaded in your browser.

Does the practice test include road signs and pictures?

Yes. 1 of the 100 questions are illustrated with a sign, signal, marking, or road scene, the way the CDL knowledge test presents them.

Is the Mississippi practice test free, and do I need an account?

It is free, with no sign-up. An optional account saves your progress across devices and shows which topics need work.

Can I pause and come back later?

Yes. A test in progress is saved on this device and offered again when you return. With an account, it is saved to your account as well, so you can continue on another device.

What score should I aim for before test day?

Aim for 80 percent or better on a Full challenge in exam mode, more than once. The official passing score is set by the agency; scoring consistently above 80 here means you are answering from the rules rather than from luck.
