Driver Dies After Crash With Stopped Semi-Truck on SR-78

One person died early Wednesday when his car crashed into a stopped semi-truck on State Route 78 in San Marcos. 

California Highway Patrol is investigating whether the big rig truck had any fault in the deadly crash.

The truck was sitting on the narrow shoulder of eastbound SR-78 just west of Twin Oaks Valley Road with no hazard lights on at the time of the crash. 

"The median shoulder is very narrow so there is not much room for that big rig to be stopped in the median,” CHP Sgt. Curtis Martin said.

The small Honda CRV crashed into the big-rig truck just before 1 a.m. The driver was pronounced dead at the scene. 

CHP is investigating reports from witnesses before the crash that said the truck possibly crashed into the center divide or that a tire was blown out before the truck came to a stop.

The semi-truck driver did not suffer any injuries and was not under the influence of drugs or alcohol at the time of the crash, Martin said. 

The crash remained under investigation for nearly 5 hours after the crash. CHP shut down all lanes at about 1:15 a.m. for about an hour to clear debris and some lanes remained closed throughout the morning. 

Lanes were expected to reopen at about 6 a.m. but just before, two cars crashed at the same location prompting another SigAlert at the same location. 

An accident on the opposite side of the freeway, on westbound SR-78 at San Marcos Boulevard, had also shut down one lane.
