With a DUI, you will most likely only find insurance in what they call “high risk” auto insurance. Most of the high risk insurance is for anyone with a DUI, too many speeding tickets, or accidents, or had no insurance or the insurance lapsed.
With a dui, then the SR22 is needed to make sure that you do not let your insurance lapse and if so, then they immediately notify the DMV, thus your license and registration is suspended till you buy insurance. In most cases will need the SR22 for 3 years and a interlock device attached to your vehicle.
Either google high risk auto insurance, or find a agent or broker that does business in many companies and then can get you the best price. Main street company or some company you never heard of, will be very expensive, thus be prepared for the shock of the price.
