Sample questions

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

Sample 1 · Alaska Cdl Classes Endorsements Restrictions And Driver Duties

Which weight configuration belongs in the Alaska Class A commercial vehicle group?

  1. A 26,001-pound-or-higher combination with a towed unit over 10,000 poundsCorrect
  2. Any single vehicle weighing exactly 10,000 pounds
  3. A combination below 26,001 pounds with no regulated cargo
  4. Any passenger car towing a utility trailer

Why: A Class A commercial vehicle is a combination with a GCWR of at least 26,001 pounds when the towed vehicle has a GVWR over 10,000 pounds. This supports the proposed answer "A 26,001-pound-or-higher combination with a towed unit over 10,000 pounds".

Sample 2 · Communication Speed Space Hazards And Railroad Crossings

At 35 mph, what minimum following interval does the manual suggest for a 50-foot commercial vehicle?

  1. Five secondsCorrect
  2. Two seconds
  3. Eight seconds
  4. Ten seconds regardless of length

Why: Below 40 mph, the manual recommends at least one second of following distance for each ten feet of vehicle length; above 40 mph, add one second. This supports the proposed answer "Five seconds".

Sample 3 · Cargo Inspection Weight Balance Securing And Special Loads

A warehouse crew loads and seals a commercial vehicle. Who remains responsible for cargo safety before departure?

  1. The driverCorrect
  2. Only the forklift operator
  3. Only the shipping clerk
  4. No one once the doors are sealed

Why: The driver is responsible for inspecting the cargo, recognizing overloads and poor balance, and ensuring cargo is secured even when another person loaded the vehicle. This supports the proposed answer "The driver".

Sample 4 · Passenger Vehicle Inspection Loading Driving And Emergencies

When should a bus driver sign the previous vehicle inspection report?

  1. Only after carrying the first passengers
  2. Whenever the report has no date
  3. After required defects are certified repaired or certified as not needing repairCorrect
  4. Before reading any listed defects

Why: A passenger-vehicle driver reviews the previous inspection report and signs it only after certified repairs are completed or the carrier certifies that repair was unnecessary. This supports the proposed answer "After required defects are certified repaired or certified as not needing repair".

Sample 5 · Combination Vehicle Control Air Lines Coupling And Inspection

Which loading and driving choice best reduces combination-vehicle rollover risk?

  1. Load one side heavily and accelerate through curves
  2. Place weight at the trailer roof to increase traction
  3. Center cargo low and reduce speed before curvesCorrect
  4. Stack heavy cargo high and brake sharply in curves

Why: Combination vehicles resist rollover best when cargo is kept low and centered and the driver slows before entering curves. This supports the proposed answer "Center cargo low and reduce speed before curves".

Sample 6 · Hazardous Materials And School Bus Safety

Where does the manual direct a hazardous-materials driver to the federal operating regulations?

  1. The passenger-car owner's manual
  2. A local weather forecast
  3. 49 CFR Parts 171 through 180Correct
  4. Only a carrier's advertising brochure

Why: The federal Hazardous Materials Regulations used by drivers are found in 49 CFR Parts 171 through 180, and a driver needs access to a current copy of applicable rules. This supports the proposed answer "49 CFR Parts 171 through 180".

How to prepare

A study plan for the Alaska 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 Alaska 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 Commercial Driver's License Manual - 2005 CDL Testing System, 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

Alaska CDL practice test questions

Is this the official Alaska CDL knowledge test?

No. DMV Exam Pass is an independent study service and is not affiliated with Alaska Department of Administration, Division of Motor Vehicles. 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 Alaska CDL practice test cover?

The 100 questions are spread evenly across 10 topics: Alaska Cdl Classes Endorsements Restrictions And Driver Duties, Vehicle Inspection Control Shifting And Visibility, Communication Speed Space Hazards And Railroad Crossings, Mountain Driving Emergencies Abs Skids Crashes Fires And Fitness, Cargo Inspection Weight Balance Securing And Special Loads, Passenger Vehicle Inspection Loading Driving And Emergencies, Air Brake Components Inspection And Operation, Combination Vehicle Control Air Lines Coupling And Inspection, Doubles Triples And Tank Vehicle Control, 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 Alaska 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 Alaska 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 Alaska CDL knowledge test?

The Commercial Driver's License Manual - 2005 CDL Testing System (Revised by the Alaska DMV 02/2018), published by Alaska Department of Administration, Division of Motor Vehicles. 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 Alaska 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.
