Under which scenario would a business auto policy cover liability for pollutants escaping from a truck?

The scenario involving the covered delivery truck discharging diesel fuel into a stream due to a ruptured fuel tank in an accident is the correct answer because it fits the criteria of liability coverage under a business auto policy. This scenario involves an unintentional release of pollutants as a direct result of an accident, which is typically covered under such policies.

Business auto policies generally cover liability for bodily injury and property damage arising from the operation of a covered vehicle. If pollutants are released due to an accident, such as a fuel spill from a truck, it is likely that the business auto policy would cover the costs associated with the resulting damages, including any necessary environmental clean-up efforts mandated by regulatory agencies like the EPA.

In contrast, the other scenarios involve varying degrees of intentionality or circumstances that wouldn't fall under standard auto liability coverage. For example, the SUV spilling cleaning solvent during transport may not be classified within the same accidental context, and the release of toxic chemicals or herbicide in the other scenarios may not be viewed as arising from an incident related to the "use" of the vehicle in the same way, missing the elements necessary for coverage under a typical business auto policy's terms. Hence, they pose different liability questions that are not explicitly addressed by the same policy
