A 24-year-old motorcyclist from Five Points died on Highway 198 near Huron when he collided with a truck trailer, the California Highway Patrol reported.
The crash took place just before 7:30 a.m. Thursday, as the rider of a 2005 Honda was eastbound on 198 near the California Aqueduct in a construction zone.
Abel Padilla of Manteca was backing up a truck with a flatbed trailer across the highway. The rider crashed into the trailer and died at the scene. His identity was withheld pending notification of family.
Neither alcohol nor drugs appear to be a factor in the crash, the CHP said.
