Flags and Meanings

Corner workers are positioned at strategic points around the track to monitor track conditions and potential hazards. Should any situation occur, a corner worker will be armed with flags and radios to alert you of any hazards. It is your job to know and pay attention to the flags and cornerworks as it directly relates to your session. Cornerworkers are essential to running a safe track event. They oversee all activity on the track and are responsible for maintaining a safe environment for you to enjoy. Each track day will have a riders meeting to go over these flags, however here is a brief description of the typical flags we use.



Speedway Children’s Charities, Sonoma Raceway Chapter ready for Action in 2016.

Thanks to the continued support of Sonoma Raceway fans and friends, the Sonoma Chapter of Speedway Children’s Charities has donated more than $5.1 million to non-profit youth organizations in Sonoma County since 2001.

The Sonoma Chapter will host 12 fundraisers during the 2016 motor-racing season at Infineon Raceway. The season is highlighted by the annual Children’s Champions NASCAR Grand Marshal’s Banquet, set for June 24 at Cline Cellars Winery in Sonoma.

The mission of Speedway Children's Charities is to care for children in educational, financial, social and medical need in order to help them lead productive lives. There are eight SCC chapters around the country, including Sonoma, which provide funding for hundreds of non-profit organizations throughout the nation that meet the direct needs of children.
