NASCAR Fines Patrick, Busch

NASCAR has fined two of its biggest names -- Danica Patrick and Kyle Busch -- for actions during the March 19-20 race weekend at Auto Club Speedway.

Patrick was fined $20,000 for walking toward Kasey Kahne's car to gesture at him as he drove under caution after turning Patrick into the wall during the Auto Club 400 on Sunday.

Kyle Busch was fined $10,000 for disobeying a NASCAR directive to do postrace interviews after the Xfinity Series race Saturday.

The penalties announced Thursday are considered behavioral in nature and fall under NASCAR's new member conduct policy, though the rules Patrick and Busch violated have existed for at least a couple of years.

Drivers involved in wrecks have been forbidden from leaving the area of their car and the ambulance to gesture at other drivers since the August 2014 tragedy involving Kevin Ward Jr. in a non-NASCAR sprint-car race. Ward approached the moving car of Tony Stewart, who has said he did not see Ward until the last moment before his car struck and killed the 20-year-old.
