Deputies said all three vehicles were headed north on the road when it happened. Damage included penetration holes in the side panels and broken window glass. No one was hurt.
Investigators said they got a tip that a teen was seen in the area with a pellet gun and went to the boy's home. A CO2 gas-powered pellet rifle was recovered and the boy arrested.
As he's a juvenile, he has not been named.
