CDL Tanker Practice Test Part 2

1. During an in-route check at a rest stop, you notice liquid dripping from the rear of your tank trailer near a manhole cover. What should you do first?

2. When transporting food-grade liquids in a tank vehicle, what additional requirement must be met compared to non-food-grade liquid transport?

3. A baffled tank has holes in each baffle plate. Why must these holes be kept clear and not blocked or sealed?

4. During an emergency stop on the shoulder of a highway, a tank driver discovers a small crack in the tank shell leaking non-flammable liquid. The driver has warning triangles, a fire extinguisher, and a phone. Analyze the correct response sequence.

5. After unloading all hazardous cargo from a cargo tank at a delivery site, when may the placards be removed from the tank?

6. A shipper provides a driver with a loading chart showing that for a particular chemical, 3% outage is required at 70°F and 5% outage is required at 100°F. The loading temperature is 85°F. What outage should the driver ensure?

7. Two identical tanks are loaded at the same temperature. Tank A contains water (low expansion coefficient) and Tank B contains gasoline (high expansion coefficient). Both are loaded with the same outage percentage. If both experience a 40°F temperature increase during transport, what will occur?

8. When performing a pre-trip inspection on a tank vehicle equipped with a bottom-loading system, which component requires specific attention to ensure it does not leak during transport?

9. Where must placards be displayed on a cargo tank motor vehicle?

10. Compared to a loaded dry van of the same GVWR, a loaded tank vehicle typically requires how much additional stopping distance?
