Md. Code, Transportation § 3–308

In any fiscal year, if the county fails to levy the tax authorized in its agreement with the Department and if the county’s share of highway user revenues is insufficient to meet the debt service on bonds in that year, the State Comptroller, notwithstanding the provisions of Title 8, Subtitle 4 of this article on the distribution of highway user revenues, may withhold from the share of highway user revenues payable to municipalities in the county an amount sufficient to pay the debt service on the bonds in that year.
