Oregon Revised Statutes Trade Regulations and Practices § 646A.142

(2)(a) No rental company shall sell or offer to sell to a renter a collision damage waiver as part of a rental agreement unless the renter is provided the following written notice in at least 10-point type:

NOTICE: Our contracts offer, for an additional charge, a collision damage waiver to cover your responsibility for damage to the vehicle. Before deciding whether or not to purchase the collision damage waiver, you may wish to determine whether your own vehicle insurance affords you coverage for damage to the rental vehicle and the amount of the deductible under your own insurance coverage. The purchase of this collision damage waiver is not mandatory and may be waived.

(b) The notice required by this subsection shall either appear at the top of the rental agreement or shall be on a separate piece of paper attached to the top of the agreement.
