To find out how long your state will keep a DUI on your driving record check with your local Department of Motor Vehicles.
The insurance premium rate increase will probably take place at your next renewal period when your insurance company checks your motor vehicle record (MVR) and sees this serious (major) offense listed. The amount of time for the increased premium will again depend upon state laws or the insurance companies own rating guidelines. In general it can affect you for 3, 5 or 7 years typically or as long as the violation is on your DMV record if state insurance laws allow it.
