Thanks for the motivation to take the next steps to be prepared. I have a go bag with with trauma gear that goes with me everywhere. I've actually used it more off-duty then on after stopping for several bad auto accidents.
The most frustrating was the one below I came across driving home one morning after work. They slammed into the retaining wall at about 70 and neither was wearing their belts. I couldn't do anything for their injuries with my gear, but I at least directed other bystanders what to tell 911 to get medics there while I assessed injuries. That wreck was the motivation to get better kit and to attend classes. It's been too long since I've attended one and your post is the motivation for me to do it.
