I have a quick question about laws. This could have been answered a bunch of times before but I've never seen it asked. As an EMT or a marked ambulance you have a " duty to act". Such as if I was walking around in my XYZ Dept Job Shirt with an EMT patch on it I'm identifying myself as an EMT and therefore I have a duty to act god forbid something happens that I come across. So getting to my point how does the Identifying yourself thing go for instance this is not a shot whatsoever, but if a Hudson Valley Paramedics ambulance ( a BLS unit) came across a MVA with heavy trauma, assuming they did all they could on a BLS level. Could that Company or EMT-B's be Liable because it says "Paramedics" on their ambulance and on the shirts they wear but however cannot perform ALS functions, in any case not just an MVA?
