A dramatic video has emerged of a motorcyclist swerving to avoid running over another rider who crashed on a racetrack in California, US.
The footage was captured using a helmet-mounted camera at the Sonoma speedway during a track day event late last month.
It shows the driver of the bike swerving at the last minute and narrowly avoiding another rider and his bike lying in the track.
Fortunately the fallen rider was able to escape without any serious injuries.
Writing online after the incident, the filmer said "Riding at a track day when out of nowhere a rider in front of me had his engine seize, locking the rear wheel and sending him over the handlebars. I was very lucky to avoid the fallen rider, his bike and the wall. The guy who crashed walked away with minor injuries."
