Oregon Revised Statutes Oregon Vehicle Code § 810.160

(1) The commission has exclusive authority to regulate, control or prohibit the stopping, standing and parking on all state highways:

(2) Road authorities other than the commission may permit angle parking on any highway where parking is subject to their jurisdiction under this section. For cities, this subsection includes authority to permit angle parking on any city street selected and designated as the route of a state highway under ORS 373.010 and, subject to the authority of the commission under this section, any state highway within the corporate limits of the city. This subsection does not allow any road authority to permit angle parking on a state highway if the commission determines that the highway is not of sufficient width to permit angle parking without interfering with the free movement of traffic.

(3) All regulations, restrictions or prohibitions imposed by the commission under this section shall be by resolution or order entered in the commission's official records.

(4) Regulations, restrictions or prohibitions imposed by the commission under this section shall become effective and have the force of law when signs or markings giving notice thereof have been placed. To comply with this subsection, the commission shall place and maintain appropriate signs or markings at such places as may be necessary to inform the public and to give notice of all regulations, restrictions or prohibitions the commission establishes under this section.

(5) Penalties are provided under ORS 811.575 for violation of restrictions placed on state highways under this section.
