Yes, i know this term is now frowned upon, but in the four years I spent working as an EMT, and now almost a year trying to get my cert BACK after letting it lapse while doing nursing prereqs I have NEVER been allowed to drive the ambulance farther than the edge of the parking lot. The insurance won't let anyone under 25 drive it, unless they have special licensing or what have you.
THAT ENDS TODAY! Today I finished my two-day EVOC class, and can now drive the ambulance. I made it through the ENTIRE slalom course, and the parallel parking, and EVERYTHING without hitting a single cone. I win!!! I can drive the ambulance!!!
