It's probably the shift light. (J/K! Couldn't help it)
Check shocks, and try rotating the tires back.
It'd help if the starting line wasn't littered with ROCKS. That's absolutely ridiculous for a so-called national event track, or any track for that matter. Always check your wheel wells and rocker panels for sand or rocks. I've seen *tons* of photos of cars with the wheels up, and a stream of junk pouring out of the rocker panel right in front of the tires.
