Which statement is true regarding transporting pesticides in a vehicle?

The statement about transporting pesticides in a vehicle that is considered true emphasizes the importance of safety and proper handling of potentially hazardous materials. When transporting pesticides, placing them in the trunk of a vehicle not only helps to secure them and prevent movement during transit but also minimizes exposure to passengers in case of spills or leaks. Ensuring that the pesticides are properly secured is crucial to prevent accidents that could occur if containers were to shift or break during transportation.

In addition, it is important to recognize that certain methods of transportation outlined in the other options could lead to safety hazards. For instance, obtaining a police escort is typically unnecessary for the routine transport of pesticides and would not be a standard practice. Similarly, transporting pesticides unsecured in the back of a truck heightens the risk of those containers being dislodged or damaged while driving, which could result in spills or environmental contamination. Lastly, placing pesticides on the roof of a vehicle is extremely unsafe as it could easily lead to loss of control over the items and potential harm to others on the road, alongside legal regulations that prohibit such practices.
