What Constitutes DUI in Florida?

Driving under the influence (DUI) means operating a vehicle while impaired by alcohol, drugs, or both (Fla. Stat. § 316.193). This isn’t limited to illegal substances, but can also include prescription medications. The legal threshold for DUI is a blood alcohol concentration (BAC) of 0.08%. For commercial drivers, this is reduced to 0.04%.

This law applies to anyone in “actual physical control” of a vehicle, meaning you don’t have to be driving to face a DUI charge. Courts may consider factors like where you were sitting, where the keys were, whether the engine was running, and whether the vehicle could be operated.

You can also face a DUI charge when alcohol or drugs impair your “normal faculties,” even if your BAC was below the legal limit of 0.08%. Because officers judge these signs through personal observation, their conclusions may be open to challenge. We can evaluate every detail of your DUI stop and arrest to build a strong defense.
