The presence of injury to another person can be an enhancement for DUI. Even with a first offense, a DUI with serious bodily injury is a felony. A determination of injury is defined as sever bodily injury or permanent disfigurement. Therefore, a minor injury or simple bruising or soreness will not form the basis for a DUI with bodily injury. This is important to note when defending a DUI because the injury must be investigated and may not end up being as severe as originally thought when the DUI was charged. Often times DUI with bodily injury requires expert witness testimony. Expert witnesses must testify to the existence and the severity of the injury. These cases can be difficult for the State to prove if the injury is not death or permanent disfigurement.
