CHARLOTTE, N.C. (AP) -- NASCAR says it will stop issuing undisclosed fines going forward and will no longer keep certain penalties private.

The practice of NASCAR issuing "secret fines" came to light midway through the 2010 season when Denny Hamlin was penalized for comments he made on Twitter. It was then learned that Ryan Newman had also been fined for critical remarks about racing at Talladega.

Last season, it was discovered NASCAR had again fined Newman without announcing it for an incident he had with Juan Pablo Montoya.

Then, on the eve of the season-ending weekend, news that Brad Keselowski had been secretly fined $25,000 for comments about electronic fuel injection. The penalty briefly took away from NASCAR's championship activities, and chairman Brian France promised to reconsider the practice.
