I need help with a scary movie from about 5 years ago.?

Question

I dont know what its called... or whos in it... I just know the opening scene has this guy in a truck and hes getting head... and when hes done he tosses the head out the window. Then you see two girls driving to that same town. Basically one chick is the killer and the guy is made up in her head. She doesnt know shes the killer until later in the movie. If anyone can help that would be great. Sorry about the crappy description.
