Yes.  There are other factors apart from your BAC and prior offenses that can affect your penalty.  Aggravating circumstances such as driving with a suspended license, causing injury or death to another person, or having a child in the car with you can cause the imposition of a harsher sentence.   Your sentence can also be increased if police officers add other charges while charging you with DWI, such as possessing drug paraphernalia, refusing to submit to a breathalyzer test or reckless driving.
