A horse float carrying four racehorses has crashed on its way to the Sunshine Coast race meeting.

Deputy stewards' chairman Daniel Aurisch said the float slid down an embankment on the Bruce Highway, 20km south of Caloundra track.

He said the float's driver and the horse's strappers had escaped serious injury.

The four horses had minor injuries.

"We had to call the police because our vets raced to the scene but were on the wrong side of the highway. Police had to stop traffic to get them across," Aurisch said.

Stewards scratched Casual Choice, Frespanol and Whiskey Allround from the Ascot Handicap and Jetsonic from the Mick Dittman Plate.

Trainer Trevor Bailey said he stopped at the scene site to help.

"Thankfully the strappers were OK and the horses were quiet," he said.
