I do not do a lot of freeway driving but have only a few small rock chips with 9500 miles of driving. And these chips are up on the hood where protective films are generally not placed. I try to stay far away from trucks, and do not follow other cars closely. I suspect you will be OK on your drive home if you are cautious.
