The State of Alabama makes it illegal to drive your vehicle if you have a blood alcohol concentration (BAC) of .08 percent or more alcohol in your system. Of course, that doesn’t mean it’s dangerous to drive only if a persons blood alcohol level is at .08 or higher. Many people drive impaired with a BAC of .05 and many accidents and deaths from DUI accidents have been the result of driving with alcohol in their system even though not being legally impaired. Actually many people drive impaired with no alcohol in their system because they are terrible and unsafe drivers, but that’s a different blog post altogether.
