I'd be your basic under-trained first responder. Initially my reaction will be to provide traffic control/blockage of the accident and make sure 9-1-1 is called. I need to pick up a few of those
Powerflare things in lieu of incendiaries. They look like they'd be very useful.
Injury-wise, I've got an
AMK Comprehensive Kit in the truck, but I'll probably add more 4x4's. I can handle bleeding, other peoples blood doesn't bother me,
my own blood bothers me if it's making a mess -- course I've never been faced with a life threatening injury.
I need CPR training, I'm so long out-of-date. . . then an ARC First Aid course.
