Light over Limon, CO

The report, as filed

It's very hard to parse out an objective description of this event from what I perceived to be happening. As I was driving west on interstate 70 approaching Limon, CO, my attention was drawn suddenly to what I thought was a large object falling at a very high speed. It seems silly, but my first thought was that a meteor was plummeting toward the earth. From my perspective, it seemed to be moving from east to west, from behind or above me to my fore. Due to the speed with which the object traveled, I thought it must be near the ground; I thought it was going to hit the ground very near me, and I instinctively prepared to brake or swerve. The logical part of my mind thought of an airplane crashing, but the color was strange, a bright yellowish-green, and the light was round and too large for the height I perceived. A yellow-green meteor is the best way I can describe its appearance, but there was no visible trail or streak. When it seemed to be a couple of seconds from impacting, the light just disappeared. There was no dimming, no alteration, it just turned off like someone had flipped a switch. I hope y'all have an explanation, because I'm really freaked out right now.
