(a) Liability imposed.--A local agency shall be liable for damages on account of an injury to a person or property within the limits set forth in this subchapter if both of the following conditions are satisfied and the injury occurs as a result of one of the acts set forth in subsection (b):
(1) The damages would be recoverable under common law or a statute creating a cause of action if the injury were caused by a person not having available a defense under section 8541 (relating to governmental immunity generally) or section 8546 (relating to defense of official immunity); and
(2) The injury was caused by the negligent acts of the local agency or an employee thereof acting within the scope of his office or duties with respect to one of the categories listed in subsection (b). As used in this paragraph, "negligent acts" shall not include acts or conduct which constitutes a crime, actual fraud, actual malice or willful misconduct.
(b) Acts which may impose liability.--The following acts by a local agency or any of its employees may result in the imposition of liability on a local agency:
(1) Vehicle liability.--The operation of any motor vehicle in the possession or control of the local agency, provided that the local agency shall not be liable to any plaintiff that claims liability under this subsection if the plaintiff was, during the course of the alleged negligence, in flight or fleeing apprehension or resisting arrest by a police officer or knowingly aided a group, one or more of whose members were in flight or fleeing apprehension or resisting arrest by a police officer. As used in this paragraph, "motor vehicle" means any vehicle which is self-propelled and any attachment thereto, including vehicles operated by rail, through water or in the air.
(2) Care, custody or control of personal property.--The care, custody or control of personal property of others in the possession or control of the local agency. The only losses for which damages shall be recoverable under this paragraph are those property losses suffered with respect to the personal property in the possession or control of the local agency.
(3) Real property.--The care, custody or control of real property in the possession of the local agency, except that the local agency shall not be liable for damages on account of any injury sustained by a person intentionally trespassing on real property in the possession of the local agency. As used in this paragraph, "real property" shall not include:
(i) trees, traffic signs, lights and other traffic controls, street lights and street lighting systems;
(ii) facilities of steam, sewer, water, gas and electric systems owned by the local agency and located within rights-of-way;
(iii) streets; or
(iv) sidewalks.
(4) Trees, traffic controls and street lighting.--A dangerous condition of trees, traffic signs, lights or other traffic controls, street lights or street lighting systems under the care, custody or control of the local agency, except that the claimant to recover must establish that the dangerous condition created a reasonably foreseeable risk of the kind of injury which was incurred and that the local agency had actual notice or could reasonably be charged with notice under the circumstances of the dangerous condition at a sufficient time prior to the event to have taken measures to protect against the dangerous condition.
(5) Utility service facilities.--A dangerous condition of the facilities of steam, sewer, water, gas or electric systems owned by the local agency and located within rights-of-way, except that the claimant to recover must establish that the dangerous condition created a reasonably foreseeable risk of the kind of injury which was incurred and that the local agency had actual notice or could reasonably be charged with notice under the circumstances of the dangerous condition at a sufficient time prior to the event to have taken measures to protect against the dangerous condition.
(6) Streets.--
(i) A dangerous condition of streets owned by the local agency, except that the claimant to recover must establish that the dangerous condition created a reasonably foreseeable risk of the kind of injury which was incurred and that the local agency had actual notice or could reasonably be charged with notice under the circumstances of the dangerous condition at a sufficient time prior to the event to have taken measures to protect against the dangerous condition.
(ii) A dangerous condition of streets owned or under the jurisdiction of Commonwealth agencies, if all of the following conditions are met:
(A) The local agency has entered into a written contract with a Commonwealth agency for the maintenance and repair by the local agency of such streets and the contract either:
(I) had not expired or been otherwise terminated prior to the occurrence of the injury; or
(II) if expired, contained a provision that expressly established local agency responsibility beyond the term of the contract for injuries arising out of the local agency's work.
(B) The injury and dangerous condition were directly caused by the negligent performance of its duties under such contract.
(C) The claimant must establish that the dangerous condition created a reasonably foreseeable risk of the kind of injury which was incurred and that the local agency had actual notice or could reasonably be charged with notice under the circumstances of the dangerous condition at a sufficient time prior to the event to have taken measures to protect against the dangerous condition.
(7) Sidewalks.--A dangerous condition of sidewalks within the rights-of-way of streets owned by the local agency, except that the claimant to recover must establish that the dangerous condition created a reasonably foreseeable risk of the kind of injury which was incurred and that the local agency had actual notice or could reasonably be charged with notice under the circumstances of the dangerous condition at a sufficient time prior to the event to have taken measures to protect against the dangerous condition. When a local agency is liable for damages under this paragraph by reason of its power and authority to require installation and repair of sidewalks under the care, custody and control of other persons, the local agency shall be secondarily liable only and such other persons shall be primarily liable.
(8) Care, custody or control of animals.--The care, custody or control of animals in the possession or control of a local agency, including but not limited to police dogs and horses. Damages shall not be recoverable under this paragraph on account of any injury caused by wild animals, including but not limited to bears and deer, except as otherwise provided by statute.
(9) Sexual abuse.--Conduct which constitutes an offense enumerated under section 5551(7) (relating to no limitation applicable) if the injuries to the plaintiff were caused by actions or omissions of the local agency which constitute negligence.
(c) Limited definition.--As used in this section the amount of time reasonably required to take protective measures, including inspections required by law, shall be determined with reference to the actual equipment, personnel and facilities available to the local agency and the competing demands therefor.
(d) Evidence.--Whenever any plaintiff claims liability under subsection (b)(1), evidence is admissible to demonstrate that the plaintiff, at any time during the course of the alleged negligence, was engaged or participating in willful misconduct, including, but not limited to, the illegal possession of controlled substances, firearms or ammunition.
