It is a contract between the state and your insurance company that if your insurance lapses while you are required to have one then the insurance company is required to notify the state. If you let your insurance lapse while you are required to have an SR-22, the first fine can be upwards of $400 and will increase exponentially for every lapse thereafter. In addition to paying a fine, the amount of time you are required to carry the SR-22 starts over. The state will determine how long you are required to have an SR-22 on your policy. The maximum length of time in the state of Utah is three years.
You might find yourself required to have an SR-22 but not owning a vehicle. In this case, you are required to have a non-owner liability policy. It is a policy that insures you and not a specific car. It, also, allows you to drive a borrowed car without being in violation of your conviction. Many companies offer non-owner insurance policies. Calling a local agent will allow you to get a quote from several different companies.
