Miss. Code Ann. § 45-1-43

On or after January 1, 2005, each state, county and local law enforcement agency that conducts emergency response and vehicular pursuits shall adopt written policies and training procedures that set forth the manner in which these operations shall be conducted. Each law enforcement agency may create their own such policies or adopt an existing model. All pursuit policies created or adopted by any law enforcement agency must address situations in which police pursuits cross over into other jurisdictions. Law enforcement agencies which do not comply with the requirements of this provision are subject to the withholding of any state funding or state administered federal funding.
