A 17-year-old Danville boy was killed in a solo car crash on state Highway 24 in Lafayette this morning, a fire captain said.
The crash occurred just after 11 a.m. on eastbound Highway 24 near the Pleasant Hill Road exit.
Witnesses told the California Highway Patrol that the driver of the vehicle was speeding before the car went off of the road and struck a tree, a CHP officer said.
The teen, who was alone in the car, appears to have died on impact, according to Capt. Robert Marshall of the Contra Costa County Fire Protection District.
Emergency responders searched for additional victims but found none, Marshall said.
The far right lane of the highway was blocked by emergency vehicles until about 2:30 p.m., according to the CHP.
The teen's name has not been released.
