Urine tests can also be used to measure BAC in Alabama, but they are less commonly used than either breath or blood tests.

What is the process for challenging a BAC test result in court in Alabama?

How do ignition interlock devices (IIDs) factor into BAC-related penalties in Alabama?

In Alabama, the penalties for driving under the influence (DUI) of alcohol or drugs include mandatory installation of an ignition interlock device (IID) in your vehicle if you are convicted. The IID requires that you submit a breath sample before the engine will start, and it records every breath sample and results. If you fail to provide a clean breath sample, the vehicle will not start. Additionally, if your BAC is over a certain level (which varies by state) when you submit a sample, your vehicle will not start. This is a significant part of the penalty for DUI in Alabama.
