Driving without insurance, or being unable to provide proof of auto insurance to a law enforcement officer when requested, is a class B traffic violation in Oregon. Oregon has a mandatory insurance law which requires every driver to insure their vehicle.
Driving without the mandated liability insurance in OR can result in fines (averaging around $300), suspension of your driving privileges and in some areas your vehicle can be towed. If a judge convicts you of driving uninsured, you will need to file proof of future financial responsibility (SR-22) with the DMV for 3 years or else your driving privileges will remain suspended.
If you are caught driving without insurance and are involved in a crash, your driving privileges will be suspended for 1 year. After the suspension period ends you will have to carry an SR-22 for 3 years.
