JACKSONVILLE, Fla. - Three firefighters have been released from the hospital, after their fire truck crashed into a light pole in Arlington Friday morning.

The engine was heading east on the service road along Arlington Expressway near University Boulevard. No other vehicles were involved.

JFRD said the firefighters aboard the engine had to be extracted from inside by crews from a fire engine that was also heading to the scene.

Firefighters were taken to UF Health before being released.

According to spokesperson Tom Francis, an investigation has been launched to figure out what led to the crash.

The crew was heading to an Arlington house fire near Rogero Road an Morgana Road. The home was unoccupied.

"We are obviously in the early stages of this and don't know exactly what transpired," said Francis.

JEA was on the scene to restore power that was knocked out when the engine hit the pole and some power lines.

The squad 4 engine involved in the accident responded to 300 calls during the month of January. It was the busiest of all four of the squad engines.
