Diamond shaped craft, red and green lights on each end of the diamond.

I am entering this event for information and comparisons to similar such events.  During the summer of 1993 I was attending night school so I could pass the 11th grade. I had just been at a friends house and was driving to night school. It was night and I was day dreaming as I was driving. I happened to look up and see a plane coming from my right hand side in the trees or low to the trees, or what I thought was a plane. You know the typical red and green lights on the wings. The area is rather woodsy but some what populated and is a well traveled road. As I approached the Y intersection which I was going to take a left on I continued to see the lights. At this moment I thought to myself "wow this plane is flying very low". In the exact moment I was in the Y intersection I looked up through my windshield to see why this plane was flying so low. But to my surprise which then turned into a horror it was no plane.
Description: Diamond shaped craft. One red light and one green light, at opposites ends of the diamond. A visible line through the diamond (from the small part of the diamond). The size was small and probably as big as a semi truck without its trailer (50-75 feet) max and maybe even smaller. Height above the trees, probably no more than 20-40 feet. Approximate tree height was about 30-50 feet. The color was black and when I say black I mean blacker than the night sky which appeared bright compared to the diamond shaped object. The skin of texture of the object looked like the underside of bark when the little worms dig their little trails but more squared off. It had very sharp corners and the thickness of the aircraft was approximately 10 feet.
The moment I acquired the object with my eyes I stepped on the gas. As I was taking a left and the aircraft was coming from my right as I had looked up seen the object and then continued to make the turn. At this moment I was very upset and scared, panicked. So I sped up as fast as I could safely drive and then realized that the object was pacing me but moving away at the same time. Because of the trees and such I could not see the object as I had in the intersection but I could see the lights dimming as I drove down the road. At the next moment I thought that there should be other cars as I was very close to the highway and a second later I saw a car approaching and then the object was to far away to see and it was gone. I was overall visibly shaken from the shock of seeing such an object and the fact that our paths crossed exactly the same time in an intersection. I continued on my way to night school.
Source of report indicates that the date of the sighting is approximate.  PD
