The Indy Racing League, sanctioning body of the IZOD IndyCar Series, has put Milka Duno on probation through December 31st, sighting rule 9.3 (C) in the IndyCar Series rule book:
The Senior Official may place a member on probation. Probation is a state of limitation upon a Member's privileges usually following an act or omission occurring before or during membership with which calls into question the Member's willingness or ability to abide by standards required for membership. The purpose of probation is to establish a process to allow a Member to prove, by the Member's conduct, that the standards of membership are understood and will be honored at all times. During probation, a member is under heightened scrutiny and a Member can be required to abide by specific standards of conduct which are more stringent than those which are otherwise applicable. If a Member violates probation, the Member is subject to a more severe penalty. The duration and condition of the probation are within the discretion of the Officials.Duno must run within 107% of the lead car on road & street courses, and within 10mph of the lead car on ovals. The pilot of the #18 Citgo Dale Coyne Racing entry will also be closely monitored for car control and interaction with other cars. If league officials find Duno in violation of her probation, additional penalties may be imposed.
Duno may contest the probation.
