A motorcyclist was airlifted to a hospital after crashing into a guard rail near Buckhorn Summit, according to the CHP. 25-year-old David Azaria of Los Angeles was headed westbound on Highway 299 Monday afternoon at a high rate of speed. Witnesses say that he passed a vehicle at high speeds and was going too fast around a curve. The 2008 Suzuki crossed both lanes of the highway and crashed into a guard rail near mile marker 2.5. Azaria sustained moderate injuries and was airlifted to Mercy in Redding. Both lanes of Highway 299 were closed for about 20 minutes. The CHP says alcohol doesn't appear to have been a factor.
