It is well-known by most drivers in Arizona that if you are caught driving with a blood alcohol concentration of 0.08 percent or above, you could be charged with drunk driving. This in turn could cost you your license and leave you facing the possibility of hefty fines or time in prison. If your BAC is particularly high, you could face even more severe charges. For example, a BAC of 0.15 or above could result in Extreme DUI charges, while 0.20 or above is termed "Super Extreme."
Something not all drivers are aware of, however, is that in some cases you could face drunk driving charges even if your BAC is below 0.08 percent. This is the case if you are under the age of 21, the legal drinking age for the state. If you are found to have any alcohol in your system while driving or in control of a motor vehicle, then you could be charged, even if you are not drunk.
As this article on DUI laws explains, this is likely to be a misdemeanor charge. Even so, it can have a significant impact on your future. A mark on your record does not simply disappear and you may find that it affects your employment prospects and even your college or housing options.
If you are faced with charges for drunk driving, an attorney may be able to provide some of the support you need. DUI investigations are not always as accurate as they should be. For example, the Breathalyzer used could have been faulty. By ensuring every aspect of your case is fully investigated, you may be able to clear your name and avoid conviction.
