Written warnings are a new phenomenon in NASCAR in 2015.
Four written warnings were issued by NASCAR following the Quicken Loans 400 at Michigan International Speedway, raising the total amount of warnings issues since the April 19 race at Bristol Motor Speedway to 44.
Dale Earnhardt Jr.‘s No. 88 team was given a warning for failing pre-race inspection too many times. The team went through pre-race inspection three times last Sunday before being given the okay to race.
Three other teams received warnings after issues going through pre-qualifying inspection. Two of those teams came from the Joe Gibbs Racing stable, when Kyle Busch and Carl Edwards‘ teams went through pre-qualfying inspection more than two times. Josh Wise‘s No.98 Premium Motorsports team was given a warning after having similar issues.
All four teams will lose 15 minutes of practice time at Sonoma Raceway next weekend in addition to the written warnings. Teams that receive written warnings in consecutive weekends or twice in the same weekend will receive a P1 penalty.
