Tank

This endorsement is required to haul any liquid or gaseous materials in a tank or tanks having a capacity of 1,000 gallons or more that is either permanently or temporarily attached to the vehicle or chassis. To receive this endorsement, applicants must pass a test. The test consists of 20 multiple choice questions. To pass, the applicant must answer at least 16 questions correctly. Test questions come from the Ohio Commercial Driver’s License Manual. Questions come from chapters covering: Driving Safely, Tank Vehicles, Hazardous Materials and Combination Vehicles. The Tank endorsement can be used with the Class A, B or C CDL.

Number of Question 20

Passing Score 16

1. If a vehicle is carrying hazardous cargo, placards must be placed:

Only on the front of the vehicle.

On the front, rear, and sides of the vehicle.

Only on the driver’s side of the vehicle.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.

2. How often are hazardous materials employees required to be trained and tested?

Once every year

Once every three years

Once every five years

All drivers must be trained in the security risks of hazardous materials transportation. This training must include how to recognize and respond to possible security threats. Hazardous materials employees must be trained and tested at least once every three years.

3. If you must cross traffic while driving a combination vehicle, you should:

Assume other drivers will make room for your vehicle.

Wait for a gap large enough for your vehicle to safely cross.

Rely only on your mirrors.

Combination vehicles require more space on the road than other vehicles. When entering or crossing traffic while driving a combination vehicle, it is especially important that there is a large enonugh gap in traffic to safely do so.

4. In low temperatures, bridges usually freeze:

After other parts of the roadway.

Before other parts of the roadway.

At the same time as other parts of the roadway.

In low temperatures, bridges usually freeze before other road surfaces. When driving in cold weather, especially when weather conditions have been wet, use special caution on bridges and overpasses.

5. In an empty combination vehicle, the stiff suspension springs and strong brakes will have:

High traction.

Low traction.

No traction.

An empty combination vehicle will come to a complete stop more slowly than a fully-loaded vehicle. With less weight in a trailer, the stiff suspension springs and strong brakes will have lower traction than they would if the vehicle carried more weight.

6. If a tank is found to be leaking, the driver should:

Drive with their emergency flashers activated.

Get the leak fixed immediately.

Continue the trip and then inform someone about the leak.

When inspecting any kind of tank, it is most important to check the tank for leaks. It is illegal to transport any gas or liquid in a leaking tank.

7. In cool weather, as the temperature begins to rise and ice begins to melt:

It is usually safe to drive.

The road will become even more slippery.

Traction will increase.

As the temperature begins to rise and ice on the road begins to melt, the road surface will often become even more slippery. Water from the slight melting will sit on top of the ice, decreasing the available traction even more. Always decrease your speed and drive with caution when traveling on slippery surfaces.
