Any ambulance corps can do it, you just have to find a corps that has officers that are willing to consider your vehicle an official agency fly car and tell the state so. On the flip side though, that means you are responsible for meeting all state requirements to, such as what equipment you carry, markings on your vehicle, having your vehicle inspected at any time by state EMS to make sure you are compliant with requirements, etc. I don't know of anyone besides Hatzolah who allows members, other than chief officers, to run red lights in their personal vehicles

Here is the link to the NYS VTL covering the topic: http://www.safeny.ny.gov/emer-vt.htm#sec375.

You could volunteer as an EMT, but your corps would need to have the state certify your personal vehicle a a corps fly car. of become a Chief officer of an FD or Ambulance corps
