§29-12A-4. Governmental and proprietary functions of political subdivisions; liability for damages.

(a) The distinction existing between governmental functions and proprietary functions of political subdivisions is not affected by the provisions of this article; however, the provisions of this article shall apply to both governmental and proprietary functions.

(b) (1) Except as provided in subsection (c) of this section, a political subdivision is not liable in damages in a civil action for injury, death, or loss to persons or property allegedly caused by any act or omission of the political subdivision or an employee of the political subdivision in connection with a governmental or proprietary function: Provided, That this article shall not restrict the availability of mandamus, injunction, prohibition, and other extraordinary remedies.

(2) Subject to statutory limitations upon their venue and jurisdiction, the circuit courts have jurisdiction to hear and determine civil actions governed by or brought pursuant to this article.

(c) Subject to sections five and six of this article, a political subdivision is liable in damages in a civil action for injury, death, or loss to persons or property allegedly caused by an act or omission of the political subdivision or of any of its employees in connection with a governmental or proprietary function, as follows:

(1) Except as otherwise provided in this article, political subdivisions are liable for injury, death, or loss to persons or property caused by the negligent operation of any vehicle by their employees when the employees are engaged within the scope of their employment and authority.

(2) Political subdivisions are liable for injury, death, or loss to persons or property caused by the negligent performance of acts by their employees while acting within the scope of employment.

(3) Political subdivisions are liable for injury, death, or loss to persons or property caused by their negligent failure to keep public roads, highways, streets, avenues, alleys, sidewalks, bridges, aqueducts, viaducts, or public grounds within the political subdivisions open, in repair, or free from nuisance, except that it is a full defense to such liability, when a bridge within a municipality is involved, that the municipality does not have the responsibility for maintain or inspecting the bridge.

(4) Political subdivisions are liable for injury, death, or loss to persons or property that is caused by the negligence of their employees and that occurs within or on the grounds of buildings that are used by such political subdivisions, including, but not limited to, office buildings and courthouses, but not including jails, places of juvenile detention, workhouses, or any other detention facility.

(5) In addition to the circumstances described in subsection (c)(1) to (4) of this section, a political subdivision is liable for injury, death, or loss to persons or property when liability is expressly imposed upon the political subdivision by a provision of this code. Liability shall not be construed to exist under another section of this code merely because a responsibility is imposed upon a political subdivision or because of a general authorization that a political subdivision may sue and be sued.
