Cherry Hills Village, CO- Authorities are trying to determine if the truck driver that caused a thirteen car pile-up in Colorado Monday afternoon suffered from a medical condition moments before the accident.

According to police, a semi-truck hauling a flatbed trailer was traveling westbound on I-285 when he plowed through an intersection at South Clarkson Street around 4:00 p.m., striking 13 vehicles waiting for the light to change.

The truck continued to travel after plowing into the vehicles, knocking down power pole and coming to rest on the lawn of a nearby apartment complex, barely missing several units. The truck’s hood was peeled back and the engine began to billow smoke.

The people sitting at the red-light had no idea what was going on at first. One witness told 7News the driver didn’t even attempt to stop.

“When my car got jostled, I was almost like — it was a joke — like, ‘Who’s pushing me,’ but then I looked over and there’s a big, giant truck cab rolling, just barreling through the intersection, and I was like, ‘Oh, this is really happening,’” witness Charles Ogans told 7News.

“And then as that happens, a bunch of glass hits me in the face,” Ogans said. “Glass everywhere, sparks was flying, it was just like out of a movie. I was scared out of my mind.”

Even though the cars involved in the accident were badly damaged, only four people were injured and no one was killed. The four victims, which included the truck driver, were taken to a local hospital for treatment of minor injuries.

Police are trying to determine the cause of the accident and exploring whether the driver suffered from a medical condition.

The truck driver works for Winslow Crane Service Co. who also owns the semi-truck. They refused to comment about the accident when contacted by 7News.

The Hampden pass was closed for at least five hours after the accident and the truck was not towed away until after 8 p.m.

Truck drivers and motorists cannot always help if they suffer from a medical condition while driving, but that doesn’t mean they can’t be held accountable for any property damage or personal injuries they cause. Although this should never happen, some drivers are not forthcoming about their medical conditions when applying for a regular or commercial driver’s license.

The majority of truck drivers on the road are honest, hardworking individuals who are concerned about keeping themselves and other motorists safe from harm, but there are others whose reckless actions give truckers a bad name.

Victims of truck accidents often suffer serious injuries and in the worst case they lose their lives. Even though truck accidents and other collisions are unintentional, it isn’t fair to expect the victims to pay for their accident-related expenses from their own pockets. A truck accident attorney will make certain this never happens and will fight to get the maximum amount of compensation their clients are eligible to receive.
