An overturned semi-truck on Highway 101 near Hetherton has traffic at a standstill while crews work to clear the wreckage, officials report.
The crash was reported around 10:40 a.m. in the southbound lanes of the highway, south of 2nd, according to California Highway Patrol logs. By 10:45 a.m., all lanes were blocked.
San Rafael Fire Chief Chris Gray says local firefighters are on scene of the solo-vehicle crash.
"The truck driver was evaluated on scene by San Rafael Paramedics and released," he said in an email at 11:25 a.m.
Here's more from the fire chief:
No hazardous materials were involved. Diesel fuel was found leaking from the truck and is now under control. A heavy tow is onscene to assist with righting the vehicle. One of the cables holding the crushed cars in place on the flat bed truck broke loose during the accident creating additional challenges for the rescuers. Firefighters will be onscene for sometime.
The chief added that traffic on the 101 will be halted for at least an hour.
"It was a miracle that no one was injured or worse," he said.
