Last night at work I was driving and a lady ran a stop sign and hit the back end of the passenger side box. The driver hit with such force that it broke the back axle and in the end caused the ambulance to flip over onto its side. Both my medic and me where able to climb out, neither one of us where badly injured just banged up.The driver in the other car has a few injuries. It had the potential to be a lot worse than it was. We both were wearing our seat belts, we didn't have a pile of our crap in the front with us, and I was going the speed limit (which was 35mph). I have pictures that i will put up later. Just a little reminder please everyone wear your seat belts, because i know there are people out there that refuse to wear them.
