Oregon Revised Statutes Oregon Vehicle Code § 825.160

(1) A person may not operate as a motor carrier on public highways of this state until the person has in effect a policy of public liability and property damage insurance.

(2) Insurance required under this section shall be provided at minimum limits the Department of Transportation by rule may prescribe, and upon such terms, conditions and provisions as the department may determine to be necessary for the reasonable indemnification of the patrons of the applicant and of the public against damage and injury for which the applicant may be liable by reason of the operation of any motor vehicle. However, the insurance policy required of a carrier or persons engaged solely in interstate commerce need not provide for the protection of their patrons.

(3) In fixing the amount of the insurance policy the Department of Transportation shall give due consideration to the character and amount of traffic, the number of persons involved and the degree of danger which the proposed operation involves.
