What is a primary safety precaution for transporting pesticides?

Transporting pesticides safely is crucial to prevent spills, leaks, or accidents that could harm the environment, the driver, or bystanders. Ensuring that the vehicle and any storage tanks are in good condition is a primary safety precaution because a well-maintained vehicle is less likely to experience mechanical failures that could lead to accidents. Additionally, secure storage tanks reduce the risk of leaks and spills during transit, thereby ensuring that the pesticides remain contained and do not pose a risk to others or the environment.

It's important to transport pesticides in a manner that prevents their exposure to extremes, and this includes not keeping them in a dilapidated or poorly functioning vehicle that could jeopardize safety. Other options would not contribute to a safe transportation method and could potentially lead to harmful situations.
