According to California Highway Patrol (CHP) Merced Communication Center, they received a call of a motorcycle crash in the northbound lanes of State Route 99, just north of Keyes Road. 

Officers from the Modesto area CHP responded, and preliminary investigation revealed that a 2023 Kawasaki motorcycle was speeding on the road. It collided with a Kia Soul, and both the motorcycle and rider were propelled forward before crashing into the back of a Ford Fusion.
