What must be displayed on each side of a pesticide service vehicle?

The correct answer pertains to the requirement for identification on pesticide service vehicles, specifically the display of the license number and company name. This requirement ensures that the vehicle can be easily identified as belonging to a legitimate pest control service, thereby promoting accountability and safety in pesticide application.

When pesticide service vehicles are clearly marked, it allows for better regulation and monitoring by authorities, as well as reassurance for the public regarding the identity and professional standards of the company operating the vehicle. This identification is critical in case of any incidents involving pesticide use, as it directly links the service to its licensed operator.

While other options may contain useful information, they do not fulfill the specific legal requirements for identification and accountability needed for service vehicles in this field. Having proper company identification helps foster transparency and trust within the community.
