 With the popularity and attention ride-sharing has received, it is no wonder that new endorsements have been created. The Public or Livery Conveyance Exclusion Endorsement, PP 23 40 10 15, defines "transportation network platform" and clarifies the public or livery exclusion in the Personal Auto Policy. This endorsement has not been approved in all states yet; however the way the industry is moving, it is entirely possible that more states will adopt it. The states in which this is effective on October 1, 2015, are Alabama, Iowa, Maine, Montana, New Mexico, Wisconsin, and Wyoming. It is effective November 1, 2015, in Colorado, Indiana, and Nevada; and effective December 1, 2015, in Delaware and Idaho.

This endorsement has since been withdrawn in all but California, Florida, Massachusetts, Oregon, and the Virgin Islands. North Carolina, New York, Arizona, Texas, and Virginia never adopted the form. The updated auto form PP 00 01 09 18 contains the definition and exclusion of Transportation Network Platforms that this endorsement provided.
