High BAC? Get a Strategic Defense.
Not all DUI charges are treated equally in Idaho. When a driver’s blood alcohol concentration (BAC) reaches an exceptionally high level, the offense may be classified as an excessive DUI.
This designation carries significantly harsher penalties than a standard DUI and should be taken very seriously. At Trilogy Law Group, we represent individuals in Boise, Meridian, Garden City, and throughout Idaho facing excessive DUI charges.
As a firm that practices DUI defense only, we can provide defense strategies based on the unique circumstances of your case as we tenaciously pursue optimum results.

What Does Excessive DUI Mean?
An excessive DUI is defined under Idaho law as driving with a BAC of 0.20% or higher, which is more than twice the legal limit for most drivers. While a typical DUI begins at a BAC of 0.08%, the excessive DUI designation reflects the increased danger and perceived recklessness associated with a much higher level of impairment.
This charge is still considered a misdemeanor for a first offense, but the consequences are substantially more severe. A second excessive DUI offense within five years, however, can be charged as a felony, leading to even more serious and long-term penalties.
How Is Excessive DUI Determined?
Excessive DUI is based solely on the chemical test result, usually a breath or blood test. Breath and blood tests are not always reliable. Improper calibration, human error, medical conditions, or contamination can produce flawed results. This is one of the many reasons why legal representation is crucial.
