Triangular craft came out of nowhere. It hovered in front of my car from a small distance.

I was driving thru Galitzlin State Forest in Somerset into Bedford County Pa on my way home from night shift. I was the only car on the road. A triangular black craft appeared in front on me on the highway. It had 3 lights. It then moved to my left and watched me. It It watched me for about 5 mins. It then quickly and silently retreated further into the sky. It was in the sky for a short period about 10 mins. Never seen anything move like that, or move that fast. No propulsion. No sound. It stayed in the sky for approximately 20 mins all together, then disappeared. I'm not crazy. I'm not seeking fame. I just want to report. It was a UFO. AIRCRAFT do not move like that!
