Following is an overview of the laws, limits, and fines as they relate to speeding traffic violations in the state of Oregon.

65 mph: some rural two-lane highways

55 mph: most other highways

25 mph: public parks

25 mph: residential districts that are outside cities and urban growth boundaries with a population of over 100,000

Oregon code on reasonable and prudent speed

Maximum speed law:

According to section 811.100(1) of Oregon vehicle code, “A person commits an offense if driving a vehicle at a speed greater than is reasonable and prudent, having due regard to all of the following: the traffic; the surface and width of the highway; the hazard at intersections; weather; visibility; and other conditions then existing.”

Minimum speed law:

Sections 811.130(1) and 811.315(1) states:

“No person shall impede the normal and reasonable movement of traffic.”

“A person driving at less than the normal speed of traffic shall drive in the right-hand lane available for traffic or as close as practicable to the right-hand curb or edge of the roadway.”

Due to variations in speedometer calibration, tire size, and margins of error in speed-detecting technology, it’s uncommon for an officer to pull a driver over for going less than five miles above the speed limit. However, technically any amount over can be considered a speed violation so best practices are to stay within the limit.

Oregon has a mix of absolute and prima facie speed laws. This means that in some cases, a driver may argue that they were driving safely, even if exceeding the posted limit. Alternatively, a driver may choose to go to court and claim their innocence based upon one of the following:

  • The driver may oppose the determination of speed. In order to claim this defense a driver must know how his or her speed was determined and then learn how to disprove its accuracy.

  • A driver may claim that an emergency situation caused the driver to break the speed limit in order to prevent injury or damage to themselves or others.

  • The driver may claim a case of mistaken identity. If a police officer clocks a driver speeding and subsequently has to find them again in traffic, it’s possible that they could have made a mistake and pulled the wrong car over.

Penalty for exceeding the speed limit in Oregon

First-time violators may:

  • Be fined up to $75 or up to $600 depending upon the class of violation

  • Have their license suspended for up to 30 days under the Driver Improvement Program

First-time violators may:

  • Be fined up to $5,000

  • Be sentenced to up to one year of jail time

  • Have their license suspended for up to 90 days

Violators may be required to participate in the Driver Improvement Program.
