What happens if I do not pay or dispute my toll charge?
(1) If a toll charge is not disputed or paid within eighty days of the toll charge being incurred, the registered owner of the vehicle incurring the toll may be assessed a civil penalty. A civil penalty is defined in RCW 46.63.160(8) plus the initial toll charge and reprocessing fee.
(2) A notice of civil penalty (NOCP) will be sent by WSDOT to notify the registered vehicle owner of the civil penalty and shall include:
(a) A certification that the license plate in the photo is the license plate of the vehicle being assessed the toll;
(b) The total amount due; and
(c) Instructions for paying or disputing the NOCP.
(3) A notice of civil penalty may include information regarding one or more toll charges that were not paid and their associated civil penalties and reprocessing fees.
