POV Response for Multiple vehicle rollover MVA with fire

Originally dispatched for a MVA with multiple rolled vehicles including fire and entrapment and involving all four lanes of the interstate. Within 7 minutes of the original dispatch, our Rescue, Tanker, Engine and Brush trucks were out the door, with two personnel responding POV. Within 10 minutes of dispatch, Rescue was on scene. As I approached the exit for our Main Station, Knowing that 4 of our trucks were either on scene or en route, I contacted my Chief (on Rescue truck, which was first on scene) to determine whether I needed to continue to scene or hold at station. The MVA turned out to only involve the southbound lanes but did have two vehicles. A Dodge Ram truck had rolled over into the median and rested on the cable barrier. The second vehicle was a 4-door hatchback on fire in the ditch on the shoulder. Negative entrapment on both vehicles. The fire was quickly extinguished, all patients were treated and/or transported and all units cleared within an hour. Three apparatuses (1 each from 3 depts) from the primary county responded and were on scene.
This section of interstate only has two exits and both are 7 miles apart, with the county line between them.
