4 Pa. Code § 39.97 – Insurance coverage.

(a) The Commonwealth provides excess liability insurance coverage for employes who use their personal vehicles for travel in the conduct of official Commonwealth business. Excess means that any other valid and collectible insurance will be primary. The coverage provided by the Commonwealth will be considered primary if no other valid and collectible insurance was in effect. Excess liability coverage is provided through the Employe Liability Self-Insurance Fund administered by the Bureau of Risk and Insurance Management, Department of General Services, and is limited to the coverage required on a per person-per occurrence basis as defined in the Pennsylvania No-fault Motor Vehicle Insurance Act (40 P. S. § § 1009.101—1009.701) (Repealed).
(b) Employes using or anticipating the use of their personal automobiles on Commonwealth business are advised that they should notify the underwriter providing liability coverage of such use or anticipated use. They shall:
1. (1) Certify as to insurance coverage on Form OA-191, Travel Expense Voucher, when seeking reimbursement for use of personal automobiles.
2. (2) Report accidents involving personal automobiles while on Commonwealth business to their insurance underwriter and the Bureau of Risk Management, Department of General Services.
(c) Compliance with the provisions of subsection (b)(1) and (2) does not relieve an operator or owner of an automobile of any responsibility to comply with the requirements of the Vehicle Code or other applicable laws or ordinances.
(d) Rates at which reimbursement is made for the use of personal automobiles include a portion to reimburse employes for additional insurance coverage required when using personal automobiles on Commonwealth business.
