IndyCar institutes new pit box rules in Baltimore after Dixon penalized at Sonoma

IndyCar has installed new rules involving drivers and the safety of pit crew members in the wake of Scott Dixon's mishap at Sonoma last week.

Dixon was on his way to victory when he received a drive-through penalty with 15 laps to go for clipping a tire in the left hand of a member of Will Power's crew. The incident occurred when Dixon's Honda left his pit directly behind Power's Chevrolet.

The rules instituted Friday define where pit crews should stand during the race.

As drivers prepared for Sunday's Grand Prix of Baltimore, IndyCar added point-of-reference "courtesy zones" to the outside edges of each pit box to aid in monitoring pit stop conduct. In addition, IndyCar added a rule which reinforces its pit stop code of conduct.
