David and Anita Sperbeck, who live near the state’s Department of Transportation facility in Voorheesville, were awakened in the early hours of Friday morning and took video of the three trucks that were burning at the facility, at the intersection of routes 155 and 85A near the village’s roundabout.

There is an active investigation underway, said Bryan Viggiani, spokesman for the state’s DOT, noting the DOT is coordinating with State Fire and the Albany County Sheriff’s Office. He declined further comment.
