It sounds as though you were driving straight ahead, the point of impact could be the driver's side door of your vehicle if you were making a turn at the time.
Case in point, years ago I was stopped at a stop sign when another vehicle entered the intersection incorrectly and, while turning, drove the side of their vehicle across the front bumper of my stopped truck's metal front bumper. The side of their car crumpled, but my front bumper just had a little paint from their car on it.
