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 1Temperature Loss Calculation
You are hauling a load of liquid asphalt at 325°F (163°C) in a 4,000-gallon tanker. The asphalt has a specific gravity of 1.05. If the ambient temperature is 40°F (4°C), and you experience a temperature drop of 1°F per mile traveled, approximately how many degrees Fahrenheit will the asphalt's temperature drop over a 100-mile trip?
- A.75°F
- B.100°F(Correct)
- C.25°F
- D.50°F
Explanation
The temperature drop is directly proportional to the distance traveled. If the temperature drops 1°F per mile, then over 100 miles, the total drop will be 1°F/mile * 100 miles = 100°F. The specific gravity and volume are irrelevant to this specific calculation.
- Question 2Hazardous Material Tanker Inspection
When inspecting a tanker designed to carry hazardous materials, which of the following would be the MOST critical to verify for structural integrity and leak prevention?
- A.The presence and functionality of the emergency shut-off valves(Correct)
- B.The cleanliness of the interior tank lining
- C.The condition of the tires and brakes
- D.The calibration of the load/unload pressure gauges
Explanation
For hazardous materials, the primary concern is preventing leaks. Emergency shut-off valves are critical safety devices designed to quickly stop the flow of product in an emergency, thus preventing or minimizing environmental damage and exposure. While other items are important, valve functionality is paramount for hazardous loads.
- Question 3Braking Techniques
You are driving a tanker truck carrying a viscous liquid. You approach a steep downgrade and need to slow down. Which braking technique is generally LEAST recommended for maintaining control of a tanker truck on a steep downhill grade?
- A.Applying the service brakes smoothly and continuously(Correct)
- B.Using engine retarder or Jake brake
- C.Applying the service brakes intermittently
- D.Downshifting to a lower gear before descending
Explanation
Applying the service brakes smoothly and continuously on a steep downgrade can lead to overheating and brake fade, significantly reducing braking effectiveness and increasing the risk of losing control. Intermittent application allows brakes to cool, while engine retarders and downshifting provide auxiliary braking.
