What is a requirement according to the Pesticides Act when leaving pesticides unsupervised in a vehicle?

Leaving pesticides unsupervised in a vehicle comes with specific safety and regulatory requirements. Displaying a Warning - Storage sign is crucial because it serves as a visible alert to anyone approaching the vehicle that hazardous materials are present. This helps to emphasize safety for the vehicle owner and others nearby, reducing the risk of accidental exposure or misuse.

It is important to note that there are strict guidelines regarding the transport and storage of pesticides, which are designed to prevent environmental contamination and ensure public safety. While the other options touch on aspects of vehicle and pesticide safety, they do not specifically address the need for appropriate signage that clearly communicates the potential hazards associated with the pesticides being transported.
