is straightforward when it comes to DUI citations. If the driver is over 21 and operating a normal vehicle, a BAC of .08 percent or higher will result in a DUI charge. If the driver is over 21 and operating a commercial vehicle, that number is reduced to .04 percent. If the driver is under 21, a BAC of .02 percent or higher will result in a DUI citation. Drunk driving is a serious offense and receiving a citation for a DUI can be stressful.
