In a standing flag start, what is the time frame for the race to start after the starter raises the flag?

In a standing flag start, the official rules stipulate a specific time frame within which the race may commence after the starter raises the flag. The requirement is that the start must occur no less than 3 seconds after the flag is raised. This is designed to ensure that all competitors have a fair and equal opportunity to respond to the start signal, helping maintain a consistent and orderly start to the race. Timing that is too short can lead to confusion and an unfair advantage for those who anticipate the start better than others.

Establishing a minimum time frame helps maintain the integrity of the race, ensuring that drivers are adequately prepared to begin racing. Therefore, the correct answer accurately reflects this standard, ensuring that race officials enforce a fair start for all competitors.
