ORS § 319.590
Any surety on a bond furnished by a user as provided in ORS 319.570 shall be released and discharged from any and all liability to the state accruing on the bond after the expiration of 60 days from the date upon which the surety has lodged with the Department of Transportation a written request to be released and discharged, but this provision shall not operate to relieve, release or discharge the surety from any liability already accrued or which accrues before the expiration of the 60-day period. The department shall promptly, upon receiving the request, notify the user who furnished the bond, and unless the user, on or before the expiration of the 60-day period files a new bond, or makes a deposit in accordance with the requirements of ORS 319.580, the department forthwith shall cancel the user's license.
