The department chair, director, or equivalent or higher administrator may grant personnel associated with the department authorization to drive state vehicles or privately-owned vehicles on official University business. Such personnel must be employees, students, or designated volunteers. The President has delegated this authority to department chairs, directors, or equivalent administrators.
Administrators may assign department staff members to prepare documents, complete verifications, and conduct training as required by this policy.
Use of University vehicles for student activities not under direct supervision by University employees, as defined under Definitions, is prohibited. Student activities are excluded from the state’s Self-Insurance Liability Program.
15-Passenger Full-Size Van (12-15 Seats)
A 15-passenger full-size van is defined as an extended version of a full-size van that is designed to accommodate up to 15 seats.
With the exception of the commuter ride-sharing program, WSU prohibited use of these vans for transporting passengers effective January 1, 2008.
12-Passenger Full-Size Van (8-12 Seats)
A 12-passenger full-size van is defined as a van with a maximum seating capacity of 12. It should not be confused with the longer 15-passenger full-size van that is configured with 12 seats or less.
Mini-Van (Up to 8 Seats)
A mini-van is defined as a passenger vehicle with a maximum seating capacity of six to eight. It is smaller in size than the 15- or 12-passenger full-size van and is commonly referred to as a “mini-van” by automobile manufacturers.
Cargo or Maintenance Full-Size Van
A cargo or maintenance full-size van is defined as a full-size van (12- or 15-seat capacity) which is designed or converted to be used for cargo or maintenance purposes only.
Official University Business
Official University business is defined as activities performed by an official or University employee, registered volunteer, or student as directed by their supervisor to accomplish University programs or as required by the duties of their position or office.
A University vehicle is defined as a motor vehicle owned, rented, leased, or otherwise under the possession and control of the University.
If a duly-authorized employee rents a vehicle at University cost and uses the vehicle solely for official University business, the rental vehicle is considered to be a University vehicle.
A student is defined as an individual who meets the University’s criteria for student status.
Student activities, including activities of registered student organizations, are defined as activities which are not under the direct supervision of University employees.
A volunteer is a person who, of their own free choice, performs any assigned or authorized duties for the University. A volunteer receives no wages and is registered and accepted as a volunteer in accordance with the policy and procedures in Business Policies and Procedures Manual, BPPM 60.81. The department must report the volunteer’s hours to Human Resource Services (HRS) and pay a workers’ compensation coverage premium.

Privately-Owned Vehicles (POVs)
Drivers using privately-owned vehicles (POVs) on official University business are responsible for complying with all policies in the Safety Policies and Procedures Manual (SPPM) and with BPPM 95.11.
Note: Several policies include exceptions for drivers using privately-owned vehicles on official University business. Such exceptions are identified below.
A driver must notify the department manager, supervisor, or assigned staff person by the end of the next business day upon notification by the applicable licensing agency that their driver’s license has been suspended, revoked, or otherwise determined to be invalid.
Drivers must operate vehicles at all times in a professional and safe manner, and comply with applicable traffic laws and regulations.
A WSU driver may transport individuals, e.g., students, volunteers, contractors, clients, and private citizens, traveling on official state or University business only.
Personnel employed by other public entities who are traveling on official public business may accompany a WSU driver if the use is for official WSU purposes.
WSU drivers are not to provide rides for any nonofficial passengers, including family members, relatives, friends, and pets.
Exception: Drivers who use privately-owned vehicles for official University business may provide rides for nonofficial passengers, provided that the drivers have private insurance that covers the passengers.
University drivers may not transport non-college-enrolled high school or younger children in full-size passenger vans or other specialty vehicles not meeting state and federal school bus standards. Drivers may transport non-college-enrolled high school or younger children in mini-vans and sedans. Transportation of children must meet the definition of official University business.

Payment of fines and citations under such circumstances is the sole obligation and responsibility of the driver and is not to be reimbursed or paid by the University.
Drivers must adjust driving speed and vehicle equipment (e.g., use of lights, tire pressure) to changing weather conditions. Additionally, the driver must alter travel plans as needed for safety due to inclement weather or sudden illness.
University owned vehicles are to be driven on maintained roads whenever possible. When official University business requires that vehicles be used off-road, the following process must be followed:
- Departments ensure their employees, students, and volunteers are authorized before driving University owned vehicles off-road.
- Departments notify Risk Management Services which of their vehicles insured with the Vehicle Accident Loss Reserve Fund are authorized to be driven off-road.
Risk Management Services may charge an additional premium or deductible for the Vehicle Accident Loss Reserve Fund for vehicles that are used off-road, depending on vehicle type and loss history.
- Departments renting motor pool vehicles must authorize the driver to go off-road for University business and notify Motor Pool that the rented vehicle is being used off-road. Off-road use incurs an additional surcharge added to the rental rate to include off-road insurance.
If departments fail to authorize and notify motor pool that the University vehicle is being used off-road, they are responsible for paying all fees and damages to repair the vehicle that is not authorized for off-road use.
Damage investigations and final assessment of damages for off-road use of motor pool vehicles are made by Risk Management Services and Motor Pool.
Drivers must follow department or Motor Pool policies for reporting vehicle mechanical problems and arranging for service repairs or maintenance. See BPPM 95.35 for Motor Pool policies.

Driving Program Sticker
Departments must affix a “WSU How’s My Driving?” program sticker to the left rear of each University-owned vehicle. Stickers are available from Risk Management Services.
Insurance Coverage Requirements
Internal Self-Insurance for Vehicle Repairs
WSU maintains an internal self-insurance fund, the Vehicle Accident Loss Reserve Fund, for repair of University vehicles for which departments pay premiums.
The department that owns the vehicle pays the annual premiums. Risk Management Services collects and deposits annual premiums submitted by departments into the fund.
Money from the fund is used to pay for repairs to covered University vehicles damaged in accidents and the administrative costs of processing vehicle-related claims. Coverage includes department reimbursement for towing or recovery involving distances up to 100 miles for University vehicles damaged in accidents. The fund does not pay for vehicle damage resulting from maintenance or related repairs, gross negligence, abuse, or neglect.
Contact Risk Management Services for the current self-insurance premiums. Risk Management Services periodically reviews and adjusts the premium as required.
Self-Insurance Liability Program (SILP) for Vehicle Tort Claims
The states DES, Office of Risk Management Division (ORM) administers the Self-Insurance Liability Fund (SILP). The SILP covers liability claims against state employees who are operating vehicles in good faith in performance of their official state duties. The state ORM:
- Assigns claims for investigation, coordinates their defense, approves settlements, and pays covered state agency tort claims from the Self-Insurance Liability Fund.
- Administers the Washington Self-Insurance Liability Program fund.
- Provides auto liability coverage for state owned and rented vehicles driven on state business in the United States and Canada.
- Provides excess liability insurance coverage on behalf of state for employees who drive personally owned vehicles on state business whose private auto insurance liability coverage is insufficient to cover damages paid to third parties.
- Assigns most vehicle claims for investigation and resolution to the ORM or to the Tort Claims Division of the Attorney General’s Office.
- Makes all tort claim payments for third party injuries and damages.
The Self-Insurance Liability Fund (SILP) does not provide uninsured or underinsured coverage for a state employee who is injured while in a state vehicle. The SILP does not pay for insurance deductibles or damage to a state employee’s personal vehicle.
See BPPM 95.12 for more information regarding the University’s rental car policies and procedures.
State Contract Rentals
Travel Services administers the state rental car contracts for WSU.
State rental car contracts generally provide liability and loss damage waiver insurance coverage under the contract base rate. Loss damage waiver (LDW) coverage provided under the base rate includes:
- Third party liability insurance coverage for payments made to other parties who sustain injury or property damage as a result of an accident caused by a state driver authorized to operate a rental vehicle.
- Repair costs for the rental vehicle.
Consult the rental contract agreements for any restrictions (i.e., age, in the case of student drivers).
Non-State Contract Rentals
Departments may obtain loss damage waiver (LDW) coverage for non-contract rental cars by placing the vehicle rentals on a University Travel Charge Card (see BPPM 95.03).
For more information, see the Travel Services website.
The department determines whether or not to purchase loss damage waiver coverage when renting a vehicle that is not included under the state’s rental contract.
If the department does not obtain liability coverage for a rental vehicle, the Washington Self-Insurance Liability Fund provides excess coverage for third party liability claims, but will not cover damage to the vehicle. The department is responsible for all repair costs for a rental vehicle if loss damage waiver coverage is not acquired on the vehicle.
Privately-Owned Vehicles (POVs)
Authorized drivers of privately-owned vehicles (POVs) used for official University business are required to comply with the State of Washington mandatory liability insurance requirements as defined in RCW 46.29 and RCW 46.30. See also BPPM 95.11.
A driver of a privately-owned vehicle involved in an accident while on official University business may be covered by their private insurance policy. This insurance policy is considered “primary” for payment of all losses and/or recoveries arising from an accident while driving a privately-owned vehicle. The cost of insurance is considered to be covered by state’s mileage reimbursement rate. Note: The state does not reimburse state drivers for insurance deductibles.
The Washington Self-Insurance Liability Fund acts as an “excess policy” in the event third party liability limits of the private insurance policy are exhausted. The Fund does not pay for damage to a privately-owned vehicle. Under certain circumstances, the state may assist in the defense and settlement of liability claims, including possible lawsuit defense, if warranted and allowed under law.
The Office of the Attorney General may represent the University driver if a lawsuit is filed against a University driver who was in good faith operating the vehicle in the performance of their official duties.
Additional Requirements for Use of Full-Size Vans
In addition to the requirements for the use of all vehicles driven for official University business (see Departmental Drivers), the following requirements apply to the use of full-size passenger vans and the use of mini-vans obtained from WSU Pullman Motor Pool.
Reduce seating in University-owned full-size passenger vans to eight passenger seat positions. Restrict commercially-leased or rented vans to eight passengers.
Note: WSU Pullman Motor Pool includes mini-vans in the following van use requirements. Other mini-vans are excluded from the following van requirements.
Commuter Ride-Sharing Program
The commuter ride-sharing program (van pool program) is permitted to use 12- and 15-passenger full-size vans with the original number of seats. The commuters must pay the program’s prorated capital depreciation and operational expenses, including a business auto liability policy.
