Containment rules are intended to do what?

Containment rules are primarily focused on the safe handling of hazardous materials to prevent leaks and spills during transportation. They provide guidelines that instruct drivers on how to safely load, transport, and unload bulk tanks carrying hazardous materials. This is crucial because containment measures are designed to minimize the risks associated with hazardous materials, such as environmental contamination and safety hazards to both the driver and the public. Proper containment practices ensure that the materials are secured and that any potential for leakage is effectively mitigated, maintaining compliance with safety regulations.

The other options, while relevant to various aspects of transportation safety and regulations, do not specifically address the purpose of containment rules. For instance, ensuring vehicles are parked in safe locations pertains more to overall safety and risk management rather than containment itself. Similarly, regulating weight limits focuses on load capacities and structural integrity of vehicles, and monitoring driver behavior deals with operational safety rather than containment protocols for hazardous materials. Thus, the focus of containment rules is distinctively on the handling and management of hazardous materials to prevent release during transport.
