Cover art for White Is Red lyrics by Death from Above 1979

I assume they are a couple dealing with a pregnancy and abortion...

My Opinion

@dieselbenz She kills herself. They initially run away from home, and he promises to love her forever, but then she tells him to get out of the car so she can take off and crash into the traffic on the opposite lane of the highway ("she went left, double line" and "she crossed the line." The white is red because her white dress is covered in blood.
