Riding in car, looked up and saw a triangular shaped object moving almost parallel with the car. When I turned the object disappeared.

I saw the object while riding on Elberta rd in Warner Robin, Ga. The object was about 300 feet above the tree line. I was a triangled shape and had three yellow lights in each angle. It was moving at a great speed and it looked as it was moving parallel with our car. When the car turned to go south on Houston rd. the object just disappeared into the night sky without a trace. The object was about 9 and 1/2 feet on each angle. After I saw the object I was stunned and surprised. I did not tell anyone else in the car what I saw becuase i did not want to be ridiculed and taunted becauseI was young at the time. I believe what I saw was of un-earthly orgin because I have never seen anything like that before. I am also not the type of person to lie or make things up. I am a strait A student and am at the top of my class too. People always can trust me. I know what I saw and it is not made up!
