The 23-year-old male was transported to a hospital in stable condition and one firefighter was also transported as a cautionary measure.

“I think it speaks to the professionalism and the training of our fire crews that were taking care of one emergency that became involved in another emergency and they were able to switch gears and quickly respond to that and render aid to that person who collided with the fire truck,” Overton said.
