You can still be charged with a DUI under the portion of the statute that prohibits operating a motor vehicle on the public highways while under the influence of alcohol to the extent that you could not operate the vehicle safely. At trial the officer will present other evidence, driving erratically, smelled of alcohol, blood shot eyes, slurred speech etc. It is not necessary to have a blood alcohol content to prove a DUI. Additionally, in Alabama if you do not submit to the Draeger, you will have to have an ignition interlock device installed on your vehicle in order to get your driver license back.
