Personal Vehicle Use

  • FAQ

An employee may use their personal car for business travel purposes, and the university will reimburse employees at the prevailing rate per mile. The mileage reimbursement on a privately-owned vehicle compensates the traveler for wear and tear, fuel and insurance coverage. No coverage is provided by Purdue for physical damage to private vehicles used on university business. 

The university reimburses mileage at either the federal or state rate, depending on funding source.  If a funding source (e.g. grant) requires the Indiana state mileage allowance, reference the Indiana Department of Administration website to view the latest memo related to mileage reimbursement.

  • If the traveler departs/returns on the weekend, a holiday, after normal work hours or a day they would not normally commute to their official station, it is acceptable to calculate the mileage from their home. 
    • The official station is defined by the IRS as the location of the permanent office, including the entire city or general area in which the ‘official station’ is located. 
  • Mileage reimbursement is limited to the lesser of expenses incurred from the departure point or from the traveler’s official station to/from the airport or final business destination. 
    • Refer to the Drive vs. Fly webpage for reimbursement limitations when choosing to drive your personal vehicle to the final business destination. 
  • When two or more staff travel together in a personal vehicle, the mileage reimbursement is only issued to the Purdue employee who provided the vehicle for business travel. 
  • Reimbursement of expenses for remote staff required to travel to campus is contingent on the employee’s agreement and date of hire. Refer to the Remote Work Reimbursement webpage for guidance. 

  • If an individual’s daily commute to and from their residence and work is not considered to be in university travel status, it is not eligible for reimbursement. 
  • If mileage for travel on campus or in the area of official duty station is considered a business expense, then reimbursement is subject to departmental guidelines. If it is not considered a travel expense, it should not be processed through Concur. 
  • Traffic fines, court costs, parking violations, etc. are not reimbursable expenses. 

Insurance

No coverage is provided by the university for physical damage to personal vehicles.

No coverage is provided by Purdue for physical damage to private vehicles used on university business. Personal vehicle liability insurance is primary in the event of an accident. The university mileage reimbursement on a privately-owned vehicle compensates the traveler for wear and tear, fuel and insurance coverage. 

It is highly recommended that a traveler rents a vehicle through Concur for business travel to ensure proper coverage and reduce liability to the traveler. 

Drive vs. Fly

Learn about the benefits of driving and flying.

  • The allowable mileage reimbursement is a maximum of $550 when the traveler chooses to drive their personal vehicle to a business travel destination where a flight would typically be required. 
  • If multiple people are riding in one vehicle, and it is determined to be less expensive than flights for those travelers, full mileage will be reimbursed. 
  • An employee who chooses to drive rather than fly long distances may be reimbursed a fixed meal allowance for a total of two full driving days—one day before and one day after the official business.
