What are rules for ambulance companies to use tax-exempt license plates?

Question: What allows private for-profit ambulance companies to run tax-exempt license plates on their vehicles?
Answer: Vehicles owned by ambulance services specifically intended for emergency response or providing ambulance services are exempt under the Minnesota State statutes. All services must have a valid license issued by the board. The license shall specify the base of operations, the primary service area, and the type or types of ambulance service for which the licensee is licensed. The licensee shall obtain a new license if they wish to expand their primary service area, or to provide a new service.
