You should have used a turn signal. It kills me when people do that. Lucky your ok, but if I were you, I would start using a signal from now on. People do that $hit over here in Jersey all the time, if they get nailed, its because of their stupidity. Signals are on the car for a reason, if your too lazy to use them, i think your too lazy to drive.

 

that sucks man, but like the others said, if someone hits you from behind its ultimately their fault/
