Affiliate sites and certain businesses require proof of financial responsibility in case of an accident. Whenever a business requests proof of insurance, they are requesting a certificate of insurance. Examples are car rental agencies, affiliate sites, and locations off-site that Ivy Tech Community College of Indiana may be using for a conference, dinner or special event. Under certain circumstances, the College should be asking for proof of insurance from outside vendors/businesses. This is discussed more in depth in the next section that explains special events.
