Some Torrington residents were woken by what sounded like explosions when a fire broke out at Mountaintop Trucking early Tuesday morning.
Three dump trucks caught fire at 50 Lincoln Avenue around 3:30 a.m., and tires popped on the vehicles, causing the explosive sounds.
The noises caused alarm in the community, but the fire chief said they are typical with this type of fire.
No one was working when the fire started, and no one was hurt.
The fire marshal will be responding and investigating what started the fire.
