I'm trying to recall a song I used to love that was often played on MTV2 and Kerrang around 2003. It's a rock song and I know it's by a group rather than an individual artist.
The video featured a couple having an argument and one runs out of their home into the road and gets run over. The other person gets to the doorway just in time to see the accident and is gutted.
I believe it was shown around the same sort of time as 'The Reason' by Hoobastank if that helps at all.
Thanks NazNomad but not that one i'm afraid. This vid was darker and the only detail I remember clearly was someone running out of the house, letting the screen door bang shut and then the other running out just in time to see the first get hit by a car.
