triangular object with 3 huge spotlights chasing our vehicle on the freewayI was driving south on I-5 just before Coalinga....near the slaughter house, when I saw a bright row of 3 lights swooping down as if it was landing parallel to the freeway on the northbound side. I thought it was a crop duster plane or something. It then lifted back up, as if it was aborting its landing and made a complete about face while flickering the row of 3 lights on and off...the lights were brighter than halogen and when they were off there was a small red and blue light. I was thinking it was gone but woke up my husband to tell him what I saw. While I weas waking him up it came directly at me at only a height of 2-3 stories, and flicked its lights off and on in my eyes almost making me not be able to drive. I thought for sure it was trying to land on the freeway ...it then about faced again, at which time my husband awakened...i told him nervously we "were being chased by a UFO"...as I finished the explanation of what I saw he said "you mean THAT? and it was directly above my...spotlighting me and literally chasing us at an extreme low altitude. We came up on an overpass and we were sure it was going to hit it. I accelerated to avoid the impact, and the craft dodged the overpass...followed us a moment longer then immediately almost disspeared. It had a stealth like shape...and was almost paper thin...with huge lights on the front and maneuvered like no conventional craft. We are thinking of reporting this to the highway patrol.((NUFORC Note: We spoke to this witness at length and found her to be a highly credible source. PD))
