SHELBYVILLE, Ky. — James Long, a jockey who won more than 300 races in his career, has died in a car accident. He was 62.

Shelby County Sheriff’s spokesman Jason Rice said that Mr. Long died Tuesday night after losing control of his car and veering into a grassy median while traveling east on Interstate 64 near Shelbyville. Mr. Long’s car catapulted before landing on its nose. He was not wearing a seat belt.

Mr. Rice said neither drugs nor alcohol is considered a factor in the wreck.

One of racing’s few African-American jockeys when he started in the mid1970s, Mr. Long won 309 races and earned more than $2.7 million in 4,029 starts from 1976 to 2008.

Mr. Long won multiple stakes races and earned his first win as an apprentice aboard Valid Appeal in the 1975 Dwyer Handicap at Belmont Park.
