Maryland Code, Transportation § 8-406

(a) A distribution of highway user revenues may not be made to any county, municipality, or Baltimore City unless the local government in its current fiscal year certifies to the Administration that revenues will be used in compliance with all applicable laws.

(b) If any highway user revenues otherwise distributable under this subtitle are not distributed by the close of the fiscal year of the county, municipality, or Baltimore City because the local government failed to make the required certification, these highway user revenues shall revert to the Transportation Trust Fund.

(c) The county governments and other local authorities are relieved from the requirements of existing local law for levying a minimum amount or rate for road maintenance, and the portions of all public local laws making any such requirement are suspended.

(d) The Secretary of the Department of Transportation may reduce highway user revenues to each appropriate local governing body in the following fiscal year by the specific amount of the cost necessary to correct individual instances of noncompliance concerning State standards of uniformity for traffic control devices.
