Criminal charges for drunk driving can be very serious, even for a first offense. In addition to the loss of your driver’s license and increased car insurance rates, you will face steep fines and potential time in jail. You may also be required to attend treatment for alcohol abuse, use an ignition interlock device in any vehicle you drive, or complete a period of probation. If someone was injured while you were driving under the influence, or if you have previously been convicted of DUI, the charges can become even more serious.
