How Long Does A DUI Affect Auto Insurance? 
Many non-standard auto insurance companies who specialize in high risk auto insurance will only go back 3 years for a DUI . So if you 're still being dinged after 3 years , you might be much better off shopping around with high risk auto insurance companies . Not only do they only go back 3 years , but they also tend to go a little softer on DUI 's than preferred/standard carriers .
