To all you people out there that are too lazy to use a turn signal, stop being so lazy!
Don't be surprised when you get rear ended because you are too lazy to use your turn signal.
It's there for a reason; you are not special and above the law. Don't stop on a major road to turn onto a side street without using your signal.
Don't sit at a light or stop sign and assume every other driver knows which way you are going to turn.
