The grammar of the instruction is correct. Win without going off-track and skidding would mean don't go of track, but you need to skid.

Win without going off=track or skidding both refer back to without.

From a boolean logic perspective, OR is correct as well. If you go off-track or you skid, it triggers the event, in this case a red flag... AND would mean that you need to do both in order to trigger a red flag.
