What type of auto insurance is required in Washington?

The only type that is actually required by law is liability insurance. You have to have at least $25000 of liability insurance. The purpose of that is to protect you if you injure someone. If you injure someone else and you didn’t intend it, then your insurance company will step in and hire you a lawyer for free and pay up to $25000 per person who you injure. That’s the kind of insurance that you’re required to get.
