The bulldozer tractor trailor scene

It felt like the film makers forgot to pause (or cut!) during this part as Max is trying to pass the tractor-trailor and gets frustrated. The driver motions Max to pass him. It felt like Max was going to be ambushed but....NOTHING HAPPENS. I know that it indictates that there is a "forbidden zone"beyond, but it feels like they ran into road construction and forgot to stop filming.
