My know-it-all, quickie analysis here; so this old Jeep Cherokee with four excellent all-season tires with lots of tread is a rear wheel drive car at the time, and the road surface is a combination of frozen water, ice, slush, and road salt brine treatment. The temperature was somewhere below freez'n ...... how cold, I don't know? The speed limit is 70-mph. So, could be this Jeep was moving at 70-mph or faster and lost its grip on the road or something? A roll-over like this can have personal injury especially if seat belts are not worn?
Maybe the local Jeep owner/driver will see this and make a comment here? "Like, whoopsie-doopsie, I was going too dang fast for the slick iced road surface and the car simply slid off the road and done flip-flopped, upside down ......omg!" There is no video of it happening, here, as per usual.
Looking closely at the four matching tires, are they all-season tires or something else? These Facebook photos from the Campton-Thornton NH Rescue really show the road surface and the tires, there, at the scene. The road looks glazed frozen ice, slippery.
Someone needs to invent a tire with retractable steel studs, where you control the tire studs that grip into the iced road just like a cat's claw and name it, Tiger Paw, for good advertising sales promotion!
You know it looks like this happened right on the bridge, crossing the Pemi River, which is a large bridge, so could be it had to do with the bridge freez'n faster and different than the road, nearby.
