How Much Will My Car Insurance Increase After A DUI? 
The penalty for driving under the influence of alcohol comes in four ways generally . There is almost always a judicial penalty which may include a suspension and a filing of an SR-21 form . This can be very costly . Frequently there is remedial drivers training , which is an additional expense . Sometimes community service is required which takes time away from work . Then there is insurance . Most companies really dont want drivers with a DUI on their record and they price accordingly . You can anticipate at least a 50 % increase in premium , but in California you also lose a good drivers discount of 20 % , so the cumulative result often leads to an increase of almost 100 % .
