This season NASCAR hopes to clear the confusion of the “No racing to the caution” rule by using computerized scoring. According to NASCAR competition director John Darby, each Nextel cup track is currently being equipped with sensors that will quickly enable scorers to identify driver’s exact running position at the time of a caution. The system is a modified version of the loop that currently exists at the start-finish line of all tracks. Expanding upon that, tracks will now incorporate multiple sensor loops that will divide each track into trap zones.(ESPN), see past nres/rules on the ‘yellow flag rule’ on my No racing to the caution page.(1-17-2004)
