Tanker Knowledge Quiz (10 Sample Questions)
1. What is "Liquid Surge"?
A. It helps you stop faster.
B. It can push your truck forward even after you stop.
C. It only happens in full tanks.
Correct Answer: B. Liquid surge is the movement of liquid in a partially filled tank. It can push the truck into an intersection even after brakes are locked.
2. Which tank structure controls side-to-side surge but NOT front-to-back surge?
A. Baffles
B. Smooth Bore
C. Bulkheads
Correct Answer: C. Bulkheads divide the tank into smaller compartments but do not have holes for flow like baffles.
3. What is "Outage"?
A. When the engine stops working.
B. The room left for liquid expansion.
C. Driving outside the lane.
Correct Answer: B. You must never fill a tank completely. Outage allows liquid to expand when it gets warm.
4. Why are "Smooth Bore" tanks used for milk?
A. They are cheaper.
B. They have less surge.
C. They are easier to clean (sanitation).
Correct Answer: C. Smooth bore tanks have no internal baffles, making them easy to sanitize but dangerous to drive due to strong surge.
5. You should be extremely cautious when driving smooth bore tanks because:
A. They have the most liquid surge.
B. They are always overweight.
C. They leak easily.
Correct Answer: A. Without baffles, the liquid moves violently front-to-back.
6. If you must make an emergency stop with a tanker, you should:
A. Use controlled or stab braking.
B. Slam on the brakes and lock the wheels.
C. Steer into the oncoming lane.
Correct Answer: A. Locking the wheels can cause a jackknife or rollover. Use controlled braking.
7. A tanker has a high center of gravity. This makes it more likely to:
A. Go faster.
B. Roll over on curves.
C. Skid on wet roads.
Correct Answer: B. You must slow down before curves to prevent rollovers.
8. When loading a tank with bulkheads, you should:
A. Fill the front tanks first.
B. Fill the back tanks first.
C. Distribute the weight evenly.
Correct Answer: C. Don't put too much weight on the front or rear of the vehicle.
9. Baffles in liquid cargo tanks do not prevent:
A. Side-to-side surge.
B. Front-to-back surge.
C. Both A and B.
Correct Answer: A. Baffles (holes in walls) primarily control front-to-back surge. Side-to-side surge can still happen.
10. How much outage is needed?
A. Depends on how heavy the liquid is.
B. Depends on the liquid type and temperature.
C. Always 10%.
Correct Answer: B. Liquids expand at different rates depending on temperature.
