INDYCAR has updated three rules in its 2013 IZOD IndyCar Series rulebook, effective beginning this weekend at Mid-Ohio Sports Car Course.
Race Restart - In the event of a restart with 15 laps or less remaining in the race, all lapped cars will be moved to the rear of the field. (7.6.1.2).
Race Procedure Penalties - If circumstances do not permit for a penalty to be served during a race, the Race Director shall declare the race results provisional and officials will review the penalty. This review is independent of technical inspection. (9.2.2).
Tires - If a car receives tire damage due to contact during a race, the two-lap requirement for that type of tire will be considered fulfilled (14.14.6.6.5).
