On DECEMBER 14th 2021 while traveling on interstate 90 from Hardin Montana to Billings Montana I hit a large granite boulder that had fallen off of a semi, I had my cruise control set where I always set it at 77 mph. The boulder was around 500 lbs and was roughly 30 inches tall by 24 wide. It launched my truck in the air and I flew about 17 to 20 feet before touching down. I impacted the boulder just to the right of center of the bumper and it tore everything from the bumper to the firewall. Extremely violent impact and I hit my head on the sun visor and chin on the steering wheel. Not one of the airbags deployed. The first person on scene was Montana Highway Dept employee who was one minute behind me. He and myself as well as the responding highway patrol were shocked that the airbags did not deploy. Since that accident I have had multiple things wrong with my neck my knees as well as my hips and back. Im pretty sure Im messed up for life.
