Four firefighters were injured when the Dallas Fire Department's Ladder Truck 24 and a concrete truck collided shortly before noon Tuesday, authorities said.
“A couple of guys are going to need some stitches, no broken bones, some bruises, sprains – things of that nature, but we do expect everyone to be ok,” said Dallas Fire Rescue spokesman Jason Evans.
The four Dallas Fire-Rescue officers have since been released from the hospital.
Dallas Police are investigating what happened. They say the fire truck was headed northeast on Hatcher Street and the cement truck was going southeast on Second Avenue when they collided. The cement truck then rolled into a Chevy pickup truck stopped at the light.
The driver of the cement truck refused treatment. The driver of the pickup truck was taken to the hospital and the passenger inside the truck was not hurt.

“It sounded like a bomb, it was like boom,” said witness Phillip Thomas. "A lot of skidding and sliding, and a lot of people panicked and ran. It was really loud.”
Evans says the truck’s lights and sirens were activated at the time of the accident.
