Signs stating that no weapons are allowed will be placed at the entrances to these buildings
The Commissioner of Public Safety finds that the Mississippi Highway Patrol substations, driver's license offices and all other buildings owned or operated by the Mississippi Department of Public Safety are subject to the Commissioner's authority pursuant to Miss. Code Ann. §§ 45-1-3, 45-3-19, and 63-1-11. These buildings are governmental buildings utilized by individuals whose safety concerns on departmental property constitute a compelling state interest.
