A Bucks County firetruck filled with firefighters on their way to a training exercise was involved in a four-vehicle accident near Doylestown Saturday morning that authorities believe may have been caused by icy road conditions.

Seven firefighters and one person from another vehicle were taken to Doylestown Hospital after the 8:45 a.m. crash. The fire company said on its Facebook page that all the firefighters were evaluated for minor injuries and released.

A hospital spokesman said one person was still being evaluated at noon.

Richlandtown Fire Chief Calvin Trovinger said his department's truck was on Route 611, headed to a training seminar at the nearby Bucks County Fire Training Center, when a northbound truck went out of control and struck the firetruck, knocking out the vehicle's rear axle.

In addition to the two trucks, two other vehicles were involved, with a total of 11 people in the four vehicles. One man was briefly trapped in his car but was freed by firefighters.

Trovinger said firefighters and trained EMTs on the firetruck assisted the civilians at the scene before the Doylestown Police Department arrived. Doylestown police are investigating the accident.

Doylestown Hospital spokesman Ron Watson said the one person remaining for treatment was expected to be released by early afternoon.

Trovinger said his Richlandtown firefighters suffered bruises, back and neck pain but had returned to work.
