What must drivers have in their possession while transporting Division 1.1 or 1.2 explosives?

While transporting Division 1.1 or 1.2 explosives, drivers are required to have a written route plan in their possession. This requirement is crucial for safety and regulatory compliance during the transport of hazardous materials. The written route plan details the designated paths that drivers must follow, avoiding sensitive areas such as large populated regions, which helps minimize risk in the event of an accident.

Having a clearly outlined route ensures that drivers know where to go and what to avoid, and it facilitates coordination with local authorities and emergency responders if needed. This route plan is a critical safety measure when dealing with explosives, as it helps manage the risks associated with their transport.

The other options, while important in general hazardous material transport, do not specifically address the critical safety protocols mandated for Division 1.1 and 1.2 explosives. For example, shipping documents and cargo manifests are essential for tracking and documenting the loads but do not directly influence routing and safety during transportation. Emergency contact information is also important for readiness in case of an incident but does not provide the specific guidance on safe transportation routes that the written route plan offers.
