I've stopped many times. I will always stop if there are no EMS on site. Its just how I roll. I often stop if I see someone with a flat tire, or hazard lights on the side of the road.
I witnesses a bad one about 10 years ago. 2 guys in a honda ran thru a stop sign, and got t-boned by a cube van. The car went flying into the ditch, where it rolled and caught FIRE!!. One occupant was unconcious, and the other couldn't get out because the doors were locked. At the time, I had a truck full of tools, so ran for a hammer, smashed out the concious drivers window and got him out. The other guy was still KO'd, but the flames were growing, so we smashed his window and dragged him out as well. By this time lots of people had stopped, but still no EMS. We got the unconcious guy out of harms way, covered him up, and prayed we didn't cause more damage to him, but better that than watch him burn! The whole car burnt to the ground!
One of the scariest moments of my life!
