A semitrailer crashed into a gas station in Fillmore Tuesday morning, causing a large fuel spill and injuring the driver, authorities said.

The incident happened shortly before 10:15 a.m. at the Shell station at 117 Ventura St., also known as Highway 126, according to Ventura County Fire and Sheriff's reports. The station is at the east end of town at the cross with Santa Clara Street.

About 60 gallons of diesel spilled from the big rig, said Fillmore Fire Chief Keith Gurrola on Wednesday. None of the diesel went into a nearby creek or storm drains, he said.

The big rig was heading westbound on the 126 when the crash occurred. The driver said he was distracted and hit a bridge abutment, knocking over a power pole and palm tree before crashing into the east-facing side of the station, Gurrola said.

The big rig hit the station's diesel pump and minimart, where a cashier — the only one in the market at the time — immediately shut off the pumps, preventing a fuel spill from the station's supply.

The gas station manager, who normally would have been in an office struck by the semi, was out running an errand at the time of the collision, Gurrola said.

The driver of the big rig was taken to a hospital for evaluation of a possible concussion, said sheriff's Capt. Timothy Ragan. The injuries were later described as minor.

The cashier was not injured.

The sheriff's initial investigation ruled out drugs or alcohol as contributing factors, Ragan said.

Port Hueneme resident William Raftery, 36, said he was riding his motorcycle back home after a trip to Santa Clarita when he saw the scene and pulled over.

"It was quite spectacular," Raftery said Wednesday.

The semi had apparently jumped a curb into the parking lot and run over a gas pump, demolishing it, before it continued into the building itself, Raftery said. He was able to look through the open doors of the market and see the "chaos" inside, he said.

Emergency crews remained at the scene as of 6:45 p.m. Tuesday as cleanup continued, sheriff's officials said.

Gurrola said the roof of the semi was higher than the building, causing it to get trapped inside and making removal difficult for crews at the scene.

Sheriff's officials said that as of Wednesday afternoon no arrest had been made.

The heavily damaged station remained closed on Wednesday, with protective fencing and pieces of police tape set up around the perimeter. A glimpse of the destruction could be seen through a gap in the fence near an alleyway.

Gurrola said the station may be closed for months and the building, which had cracks on all sides and was moved off its foundation by the impact, will need to be rebuilt.
