This video is, ahem, turning some heads.

Sergeant John Perrine, a state trooper in Indiana, has gone viral for this amusing video in which he introduces us to a feature standard in all cars called a turn signal.

He then goes on to explain what it does and how it can make the roads safer for everyone. As Perrine reminds us, "It's not only against the law not to use it, but it's the courteous thing to do."

Perrine certainly has his tongue planted firmly in cheek while he makes his pitch in an attempt to encourage safe driving. In an era when distracted driving is a problem, this is a snarky heads-up that the simple and little things can go a long way to making sure the road poses fewer hazards than they need to while behind the wheel.
