What are the Indy 500's qualification rules?

Answer 1

NDIANAPOLIS 500 QUALIFYING PROCEDURES: Qualifications are also known as Time Trials. This means the drivers compete to see who is the fastest and gets to start the race close to the front. The qualifying draw for positions is conducted in first-come, first-serve order the day before 1st Day of Qualifying, ie. the drivers draw to see who is going to get to qualify first, second, third, etc. Drivers generally will be trying to qualify both their primary car and a backup (T) car. The pole position is decided by the fastest qualifier on the first day, or the fastest qualifier after one trip through the original qualifying line, whichever comes LAST. Each car can make three qualification attempts. When a car completes a four-lap, 10-mile qualification attempt, its speed becomes official. The car may not re-qualify. The driver, if the car is bumped or withdrawn, may qualify in another car. Each car must take two warm-up laps. The decision to take the green to start the attempt or wave off must be made the second time past the flagstand. The team owner or designated representative must raise the green flag to signify the start of a qualification attempt or the yellow flag will be thrown, aborting the attempt.
