earned the tag

Situation that drivers encounter when some a-hole in the other car makes a dumb manuever. Then you notice their handicap license plate. It becomes evident that they "earned the tag"

ME: "YOu won't beleive what happened on they way home. I was on the highway and this jerk off enterered the road without merging. After I slammed on the brakes to avoid hitting someone who truly deserved it did I notice the handicap tag."
You: "Yeah, they must've earned the tag... what are you gonna do?"
