I have three of them, and three of the other bits (with 'finish', '1' & '2' written on them?) plus some single lane pieces.krazcustoms said:It's from the Nascar Super Sound racing set. There should be another piece of track just like that one, but without the sound unit and lights. It's designed to work as a "pit" area. After a certain amount of laps, you are required to pit and if you drive over that track slowly, your car will go into the pit lane. It's a pretty neat idea, actually. The single lane pieces you have in the picture aren't installed correctly. The pit lane should parallel the main track.
