Sample Delaware Tanker Test Questions

Question 1

An empty tank vehicle generally stops in less distance than the same vehicle when fully loaded.

  1. A True
  2. B False

Correct answer: B – False

An empty tank vehicle may require more stopping distance than a full one. Heavy-vehicle brakes, tires, springs, and shock absorbers are designed to perform best when the vehicle is loaded, while an empty vehicle has less traction. Delaware’s CDL manual warns drivers to account for the additional stopping space an empty tanker may need.

Question 2

What hazard can result from liquid surging from side to side in a tank vehicle?

  1. A A cargo containment breach
  2. B A vehicle rollover
  3. C Immediate suspension failure
  4. D No significant handling problem

Correct answer: B – A vehicle rollover

Baffles help control forward-and-back liquid movement, but they do not prevent side-to-side surge. The Delaware manual warns that this lateral movement can cause a tank vehicle to roll over. Drivers must account for the rollover risk whenever liquid can shift across the tank.

Question 3

Which center-of-gravity position provides the safest handling for a tank vehicle?

  1. A As high as possible
  2. B As low as possible
  3. C Concentrated toward the rear
  4. D Concentrated toward the front

Correct answer: B – As low as possible

A lower center of gravity gives a tank vehicle greater stability. When much of the load’s weight is carried high above the road, the vehicle becomes top-heavy and easier to roll over. Tankers are especially vulnerable and can overturn even at posted curve speeds, making a low center of gravity the safer condition.

Question 4

Compared with a baffled tank, a smooth-bore tank has especially strong forward-and-back liquid surge.

  1. A True
  2. B False

Correct answer: A – True

A smooth-bore tank has no internal baffles to slow the liquid’s movement. As the vehicle starts or stops, the load can surge strongly forward and backward. Baffled tanks allow liquid to flow through openings, but their baffles help control this lengthwise surge.

Question 5

How should you drive a tank vehicle through a curve?

  1. A Accelerate before entering the curve
  2. B Reduce speed before the curve, then accelerate slightly through it
  3. C Maintain the posted curve speed throughout
  4. D Wait until entering the curve to brake

Correct answer: B – Reduce speed before the curve, then accelerate slightly through it

Reduce speed before entering the curve, then use slight acceleration while traveling through it. This is the recommended technique for maintaining control of a tank vehicle in a curve. A posted curve speed may still be too fast for a tanker, making advance speed reduction essential.

Question 6

Which cargo is commonly transported in an un-baffled, or smooth-bore, tank?

  1. A Gasoline
  2. B Food products such as milk
  3. C Corrosive acids
  4. D Very dense industrial liquids

Correct answer: B – Food products such as milk

Smooth-bore tanks are commonly used to transport food products such as milk. Baffles are difficult to clean, and sanitation requirements prohibit their use in these tanks. Without baffles to slow the liquid, forward-and-back surge is strong, requiring particular caution during starts and stops.
