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 a liquid with a specific gravity of 0.95. If the tank's maximum allowable gross vehicle weight is 80,000 lbs, and the empty weight of the tractor and trailer is 35,000 lbs, what is the maximum allowable weight of the liquid that can be carried?
- A.32,350 lbs
- B.45,000 lbs
- C.41,900 lbs(Correct)
- D.37,500 lbs
Explanation
The maximum allowable liquid weight is the difference between the maximum gross weight and the empty weight: 80,000 lbs - 35,000 lbs = 45,000 lbs. The specific gravity (0.95) is a distractor as it relates to the *volume* the tank can hold based on weight, not the maximum weight itself allowed by regulation.
- Question 2Hazardous Materials Tanker Inspection
When inspecting a tank vehicle designed to transport hazardous materials, which of the following is MOST critical for ensuring structural integrity and preventing leaks under pressure?
- A.Inspecting the welds and seams of the tank shell for any signs of corrosion or cracking(Correct)
- B.Ensuring the vehicle's lighting system is fully operational
- C.Verifying the condition of the emergency shut-off valves and their accessibility
- D.Checking tire pressure and tread depth
Explanation
For hazardous material tankers, the integrity of the tank itself is paramount. Cracks or corrosion in welds and seams can lead to catastrophic failures and leaks, which are far more critical than tires or lights in this context. Emergency valves are important, but secondary to the tank's structural soundness.
- Question 3Driving Techniques and Vehicle Dynamics
You are driving a tanker truck with a load of liquid that is sloshing significantly. What is the primary danger associated with this phenomenon, and what is the recommended corrective action?
- A.Increased braking distance due to inertia; brake gently and smoothly
- B.Engine overheating due to increased load; pull over and allow the engine to cool
- C.Reduced steering control and potential for rollover; reduce speed and avoid sudden maneuvers(Correct)
- D.Uneven tire wear; adjust tire pressure as soon as possible
Explanation
Liquid surge (sloshing) creates dynamic forces that can push the vehicle sideways, reducing steering control and increasing the risk of rollover, especially during turns or sudden braking. The primary corrective action is to reduce speed and avoid abrupt steering or braking.
