Many insurance companies check your motor vehicle record only once every three years or when you're applying for a new policy. Sometimes, accidents, tickets, and drunk-driving convictions can escape your insurer's attention or don't end up on your motor vehicle record. However, if your insurer does find out about a driving under the influence (DUI) conviction, you're likely to feel the pinch of higher rates and possibly policy cancellation or non-renewal. Rates can be doubled or tripled, although this may be a price-gouging tactic. Shopping around will definitely yield the lowest rate, as they vary greatly.There are two ways insurance companies generally deal with customers convicted of DUI. First, your insurer will likely raise your insurance premiums and label you a high-risk driver if it finds out you've been convicted of DUI. In this case, you'll likely have to file proof of insurance for three — sometimes five — years with your state's department of motor vehicles. Your insurance company will have to provide the DMV with an SR-22 form, which removes your license suspension by providing the state with proof of insurance. An SR-22 also means your insurance company is required to notify the DMV if it cancels your insurance for any reason.
