Unsecured load in the back of dump truck, several pieces of long plastic wrap type stuff few out of the back of the box while I was following it for 2 kms. I stopped and talked to the drive about it when he pulled into a drive. He seemed indifferent and blew me off. I believe in talking to your neighbors before reporting them, but he wasn't sorry or seemed to care, so I think he needs reported so he will change his ways.
