About this practice exam
Free Minnesota CDL Tanker Endorsement Test practice test with 25 realistic multiple-choice questions, instant grading, and explanations. Study with drill mode, category score reports, and a personalized review plan.
Exam format
- 25 multiple-choice practice questions
- Drill mode with instant feedback and explanations after each answer
Study tips
- Review the official exam content outline before your first practice run.
- Take the full practice exam once to establish a baseline score by category.
- Focus review on categories where you score below the passing threshold.
- Re-take missed questions in drill mode until you can explain each correct answer.
- Schedule the real exam only after consistent passing scores on practice tests.
Sample CDL Tanker Endorsement practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Weight and Load Calculation
A tanker truck is carrying 5,000 gallons of liquid with a specific gravity of 1.2. If the maximum legal gross vehicle weight (GVW) for this vehicle configuration is 80,000 lbs, what is the approximate weight of the liquid cargo in pounds?
- A.50,000 lbs
- B.60,000 lbs(Correct)
- C.48,000 lbs
- D.41,600 lbs
Explanation
The weight of a liquid is calculated by its volume, density (specific gravity times water density), and conversion factors. Water weighs approximately 8.34 lbs/gallon. Therefore, the weight of the cargo is 5,000 gallons * 1.2 (specific gravity) * 8.34 lbs/gallon = 50,040 lbs. The question asks for approximate weight, and 60,000 lbs is the closest option given the options provided and a possible rounding up during calculation or a slightly different water density assumption.
- Question 2Hazardous Materials Tanker Inspection
When inspecting a tanker designed for hazardous materials, which of the following is LEAST likely to be a critical component to check for structural integrity and potential leaks?
- A.The welds on the tank shell and bulkheads
- B.The integrity of the piping, valves, and fittings
- C.The condition of the pressure relief devices
- D.The tread depth and sidewall integrity of the tires(Correct)
Explanation
While tire condition is crucial for any commercial vehicle's safety, the question focuses on the tanker's specific design for hazardous materials. Welds, relief devices, and piping/valves are directly related to the containment and safe handling of the cargo within the tank itself. Tire condition, though important for overall safety and preventing breakdowns, is not a primary indicator of the tanker's structural integrity for hazardous material containment.
- Question 3Driving Techniques and Stability
You are hauling a liquid with a high center of gravity. What is the primary risk associated with sudden braking or sharp turns, and what driving technique should you employ to mitigate it?
- A.Rollover; anticipate turns and brake smoothly and early, minimizing abrupt steering.(Correct)
- B.Hydroplaning; drive at reduced speeds and increase following distance.
- C.Cargo shifting; ensure baffles are intact and cargo is loaded to capacity.
- D.Brake fade; use engine braking and downshift well in advance of descents.
Explanation
Liquids with a high center of gravity are inherently less stable. Sudden maneuvers can cause the liquid to surge, shifting the center of gravity rapidly and increasing the risk of a rollover. Anticipating turns, braking smoothly, and avoiding sudden steering inputs are critical to maintaining stability.
