Most companies surcharge you 5 years for a major violation such as: DUI, reckless op, etc. You should see a big difference the first policy renewal following the 5 year anniversary date of the DUI.

If you don’t you will be paying a surcharge even though your DUI has been longer than 5 years. Also I would check out now some of the following links.
