PAWTUCKET, R.I. (WPRI) — An investigation is underway after five tractor-trailer trucks caught fire in Pawtucket Thursday afternoon.

Smoke could be seen billowing from the RoadOne truck yard on Prospect Street, where all of the tractor-trailers were parked.

Deputy State Fire Marshal James Given believes the fire started in the cab of one of the trucks and spread to the others.

RoadOne is described as a logistics company that handles the shipping of goods across the country.

Given said all of the tractor-trailers are owner-operated, adding that the impacted drivers are in shock.

“It’s got to be very difficult,” he said. “These vehicles are how these people make their living, so if they don’t have a truck, they’re not working.”

Given said two personal vehicles, a pickup truck and a sedan, were also damaged.

The truck where the fire is believed to have started is heavily damaged, according to Given, which will make determining the cause difficult.

No one was injured.
