Where should all pertinent documents be located when transporting dangerous goods?

When transporting dangerous goods, it is critical to have all pertinent documents readily accessible. Keeping these documents within reach or in a pocket mounted on the driver's door ensures that they can be easily accessed in case of a roadside inspection or emergency situation. This positioning allows the driver to immediately present the necessary paperwork, such as hazardous materials manifests or emergency response information, without needing to search through the vehicle.

Having the documents accessible not only fulfills legal requirements but also enhances safety for the driver and others on the road by ensuring that the driver is prepared to handle any situation that may arise related to the dangerous goods being transported. Other options, such as storing documents in the trunk, under the passenger seat, or in the glove compartment, do not provide the same level of immediate access and can significantly delay response time in an urgent scenario.
