Yes it is! That is called a DRAG TREE. You roll up to the starting line, and there two beams shooting across the track. When the front tire breaks the first beam, you are pre-staged. When the tire breaks the second beam, you are staged. There is a timer that records the reaction time, which is the difference between when the green light comes on, and the staged beam is broken. Races can be won or lost by the reaction time. When both cars are staged, the button is pushed. The three yellow lights go off one, two, three to GREEN. They race to the end where the tires break a third beam and measures the exact time for the run. The red light is if the tire breaks the staged beam before the green light comes on. If you red light, you lose. My friends daughter red lighted with a reaction time of 0.001. It was almost a perfect reaction time.
