The fire at Missouri State Highway Patrol's Troop F maintenance facility was ruled accidental.
Fire authorities said they believe the fire started under a back passenger seat of a patrol pick-up truck which was parked in a bay in the south side of the garage.
They also said they could not rule out an electrical cause of the fire.
Considering the loss of the vehicles inside the facility and the equipment, the total loss could range from $4 million to $5 million.

The Missouri State Fire Marshall is investigating an overnight fire at a Missouri State Highway Patrol maintenance building.
The fire happened on Tuesday at about 1:15 a.m. at the Troop F facility on Shamrock Rd. off Highway 50.
Missouri State Highway Patrol Captain Tim Hull said the investigation is ongoing and does not appear to be suspicious.
The fire happened where maintenance bays for patrol vehicles are located.
Ten patrol vehicles were there at time of the fire, including cars, pick-up trucks and an SUV.
Hull said most of the vehicles will be considered total losses.
A storage area in the same facility suffered heavy smoke and water damage.
Hull said the patrol is fortunate since it has other facilities to shuffle people around so that they can still service vehicles.
The fire caused up to $1 million in damages
