In Washington State, anyone operating a motor vehicle must have an insurance liability policy, a certificate of deposit, liability bond or if you have more than 26 vehicles, be self-insured. Carrying liability insurance on your vehicle is the most common way of showing financial responsibility.
The Mandatory insurance law, Title 46 of the Revised Code of Washington, notes that as a Washington motorist you must carry with you an insurance identification card verifying you have a valid vehicle insurance policy. The current mandatory limits for WA are 25/50/10.
If you are found operating a motor vehicle without having proof of meeting the requirements of the mandatory insurance law you are committing a traffic violation. This infraction of the law is punishable by a minimum fine of $250. There are other fees and assessments that can be added to this fine so it typically costs about $450.
There is also a public safety and education assessment that will be part of your penalty. A ticket for driving without insurance is like any other traffic infraction and will become part of your WA driving record.
