State Highway Sign Regulation

The State Highway Administration (MSHA) regulates signs within the right of way and outdoor advertising signs on private property adjacent to State roads, according to Federal and State laws. These signs include official traffic safety signs and informational signs all of which are either regulated by State law, or maintained or issued a valid permit by SHA.

Signs placed on State rights-of-way that do not fall under those categories are considered illegal. Beginning October 1, 2011 a new law went into effect making illegal signs subject to removal, and businesses and individuals who place such signs will be fined.

For more information on the new law including frequently asked questions, visit the MSHA website. To file a complaint, click on the link below for Maryland DOT State Highway Administration, click on the "Customer Service", then click on the "Service Request Form" under Non-Emergencies.
