HAZMAT CDL Practice Test

What must portable tanks display?

1. Total weight

2. Type of hazardous material

3. Owner's name

4. Emergency contact number

The correct answer is: Total weight

Portable tanks must display specific information to ensure safety and compliance with hazardous materials transport regulations. The correct answer indicates that portable tanks should show the total weight. This is critical because knowing the total weight helps in proper handling and ensures that the vehicle transporting the tank is not overloaded, which is essential for maintaining safe operation on the road. Additionally, the total weight contributes to understanding the weight distribution and stability of the tank during transport. While other information, such as the type of hazardous material and emergency contact details, is important and often required, these do not specifically pertain to the total weight of the tank itself. The owner’s name is also relevant but is not a requirement for labeling the tank in terms of safety regulations. The focus on total weight emphasizes the importance of understanding the physical characteristics of the tank to promote safe transportation practices.
