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. Each question has four possible answer choices. To pass, the applicant must answer at least 16 questions correctly. Test questions come from the Colorado Commercial Driver 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.
1. Of the following, which is not a way to prevent drowsiness during a trip?
Driving while fatigued can be extremely dangerous. Strategies for preventing drowsiness while driving include getting a full night's sleep before a trip; having someone ride with you so you can take turns driving; scheduling trips for times during which you are normally awake; and avoiding medications that may cause drowsiness.
2. What is the purpose of a vehicle inspection report?
A vehicle inspection report allows a driver to inform the motor carrier of issues that could affect the safe operation of a vehicle. If required, the driver should fill out a vehicle inspection report after every day of driving. They should make note of any issues that could affect the safety of the vehicle or that could lead to a mechanical breakdown.
3. Steering wheel play should be no more than:
Steering wheel play of more than 10 degrees (about two inches of movement at the rim of a 20-inch steering wheel) can make it difficult to steer.
4. Passive railroad crossings:
Railroad crossings that are not controlled by any type of traffic control device are known as passive crossings. The decision to proceed across tracks at a passive crossing is entirely up to the driver.
5. Large combination vehicles take the longest amount of time to stop:
Large combination vehicles take longer to stop when they are empty than when they are loaded. The decreased weight causes a vehicle's wheels to have decreased traction on the surface of the road.
6. If a vehicle has a vehicle inspection report, the driver:
For the first step of a vehicle inspection, you should review the last inspection report on your vehicle, if there is one. The carrier should have repaired any problems noted on the report.
7. If cargo containing hazardous materials is leaking, the driver should:
In the event of a leak in a cargo of hazardous materials, do not continue to drive any longer than is necessary for safety. Continuing to drive would result in a larger area becoming contaminated. Instead, park the vehicle, secure the area, stay with the vehicle, and send someone to get help.
