We've all wanted to give bad drivers a piece of our mind once or twice, so just imagine how fed up Indiana state trooper Seargeant John Perrine must be when he catches drivers not following the rules of the road.
To help keep his streets safe, Perrine has taped his own public safety announcement about an "incredible" feature that will "prevent crashes, but also prevent road rage a little bit": the turn signal.
Watch him introduce this revolutionary new device in his clever video:
He might have been having a little fun, but the trooper is sharing a serious message and he found a way to spread it really far.
Since he posted the video on Facebook last week, it's been watched more than 11 million times. So if you notice a few more people using their blinker this week, you know who to thank!
