  • Zero car - Used in rallying. Prior to the rally cars running over a special stage several official vehicles run through the course to check for safety, conditions of the road, to see if spectators or animals may be a hazard or for obstructions.Sometimes there are a triple zero (000) and double zero (00) as well as the zero. Zero cars travel the course immediately ahead of the competitors and are usually rally cars themselves.
  • Zero Light - Also known as "cutting a zero," and a "zero R.T." Used in drag racing when someone leaves the starting line at the exact moment when the light turns green (.000). Very difficult to achieve, due to the quick flashing of the lights on a Pro tree.
