He stopped and reversed into him to make it look like he got rear ended!
You can’t get away with things like this when the other driver has a dash cam! Like the title says it saved his career and it really did if not for the camera no one would have believed him that the truck drove back into him. It would just look like a common reared and him trying to cover it up. He’s lucky he had it running so the truck in front can get all the consequences for what happened! It’s hard to believe that someone would actually do that to someone else epically when it’s a fellow truck driver.
