Beginning July 1, 2017, and annually thereafter through July 1, 2021, the Commissioner shall make a determination whether, with regard to the required coverages under § 10–405(a) of the Public Utilities Article, there is a viable, affordable, and adequate market of authorized insurers in the State, including the Maryland Automobile Insurance Fund, available to provide the required coverages to the transportation network services industry. To the extent that the Commissioner makes an affirmative finding of availability, and in accordance with the provisions of Title 3, Subtitle 3 of this article, it is the intent of the General Assembly that required coverages be obtained from authorized insurers and the Maryland Automobile Insurance Fund.
