“I'm completely devastated to hear about Jason Leffler," contributed Trevor Bayne. "It doesn't seem real. Pray for his family tonight."
“Sitting here in disbelief,” agreed Elliott Sadler. “All I can think about is Charlie. Prayers to his little boy.”
"Such sad news tonight," wrote Nationwide rookie Kyle Larson. "Leffler was a great person and even better dad. I am glad I got to know him. Rest in peace."
"We are very saddened at the passing of Jason Leffler," said Indianapolis Motor Speedway Chief Operating Officer J. Douglas Boles in a statement. "He was one of the most versatile race drivers in America, showing his talent by competing in the Indianapolis 500 and the Brickyard 400 at the Indianapolis Motor Speedway during his career.
"He also displayed the skills that would help him reach the top levels of the sport by winning four USAC national series titles while winning on tracks throughout the Midwest. Jason was a terrific guy who always had time for everyone. Our deepest sympathies are extended to his entire family, team and fans."
The IZOD IndyCar Series also said said that it "extends its deepest sympathies and condolences to the family of Jason Leffler for their tragic loss. Jason was a USAC champion who made three IndyCar starts, including the 2000 Indianapolis 500. Our thoughts and prayers are with his family during this difficult time."
IndyCar star and former Formula 1 driver Justin Wilson tweeted: "Another reminder of how this sport we love can be so cruel. Thoughts with his family."
"Praying for all of Jason Leffler family, especially his little guy Charlie," added IndyCar team owner/driver Ed Carpenter.
Bridgeport Speedway immediately suspended racing for the remainder of Wednesday night after Leffler's accident, which sadly is far from being the first fatal dirt track incident in recent months.
Just two weeks ago, 22-year-old driver Josh Burton died of the injuries that he sustained in a crash at Bloomington Speedway in Indiana, while two drivers were killed in a race in Nevada. In March, two died on pit road after a car spun off the track in California.
