Answer
For domestic rentals secured through the Vehicle Rental Agreement's authorized rental agencies, no additional insurance is required beyond what is included in the rate for business rentals when reservations are made through the Ohio State's Web Reservation link or through the contracted travel agency.
Note: When reserving internationally (including Canada and Mexico), contact the applicable rental agency or travel@osu.edu to determine whether insurance coverage is included in the rate. In most countries the required insurances are not included and must be purchased to meet Travel Policy requirements.
