Asked by user in California. Answered by Enjuris Editors.
Under California law, the required automotive liability policy insures a person driving a car with the owner’s permission, even if the driver isn’t listed on the policy. It’s hard to say for sure what the $900 fee was for without knowing the facts of your situation (for example, why you were pulled over), but you could certainly call the court and request clarification.
Perhaps the proof of insurance that you sent was insufficient. If you can’t get a satisfactory answer from the court or if you’re still questioning the fine, you can find a California lawyer who might be able to provide more specific guidance based on the documents and facts.
