At least 12 fans and one driver were injured after a crash at the Daytona Speedway sent car debris flying over the barrier and into the crowd near the end of the Nationwide NASCAR race.

A hospital official at Halifax Health Medical Center in Daytona Beach, Florida, told the Daytona News Journal that 11 spectators were being treated in the emergency room, with two of them critically injured.

Four of the fans were on trauma alert and five were being treated as non-trauma cases, the newspaper reported.

Florida Hospital Memorial Medical Center in Daytona Beach had one patient from the crash and was expecting three more, spokeswoman Lindsay Rew said.

The crash sent driver Kyle Larson's car airborne, although he climbed out of the wreckage afterward.

The Nationwide race was an event before today's prestigious Daytona 500 race.
