Boise Felony DUI Lawyer

Defense Firm Serving Meridian, Garden City & Statewide Clients

Felony DUI charges are among the most serious impaired driving offenses in Idaho. These charges are based on aggravating circumstances that elevate a misdemeanor to a felony, involving harsher penalties than a “standard” DUI. 

When facing a felony DUI, it is essential to partner with a law firm that concentrates its practice on this complex practice area. At Trilogy Law Group, DUI defense is our only focus. Because of this, we understand the nuances of DUI law, procedures, investigations, and defense tactics in building aggressive strategies seeking optimum results. 

People arrested for a potential felony offense often have prior DUI history, are dealing with an accident involving injuries, or are worried about what a long prison sentence could mean for their families. A felony drunk driving attorney Boise defendants can trust will take the time to explain how Ada County and other Idaho courts typically handle these cases, what options may be available, and how local procedures at places like the Ada County Courthouse can affect the timeline of the case. Understanding these practical issues early can reduce anxiety and help you make informed choices about how to move forward with your defense.

Felony DUI Charges in Boise and Idaho

In Idaho, a DUI can be charged as a felony under several circumstances.

• Third DUI within 10 years: If you have two prior DUI convictions within the past ten years, a third or subsequent DUI is a felony. 
• Second Excessive DUI within five years: If you are convicted of a second "excessive DUI" (BAC of 0.20% or higher) within five years of the first, it will be charged as a felony.
• DUI within 15 years of a previous felony DUI: Any subsequent DUI conviction within 15 years of a prior felony DUI conviction will also be a felony. 
• Aggravated DUI: If you cause "great bodily harm, permanent disability, or permanent disfigurement" to another person while driving under the influence, it is a felony, regardless of your BAC level or whether it is a first offense. 
• Vehicular manslaughter: If a death results from driving under the influence, it is charged as felony vehicular manslaughter.

Because the line between a misdemeanor and felony charge can significantly change the stakes, it is important to understand why prosecutors in Boise or elsewhere in Idaho may decide to pursue a felony and what evidence they will rely on. A felony drunk driving lawyer Boise residents consult can review prior convictions, police reports, and any accident documentation to determine whether the felony enhancement is appropriate and whether there are factual or legal arguments to challenge the charging decision. This kind of early analysis can influence plea discussions and how your case is presented in court.

Building a Felony DUI Defense Strategy

After a felony DUI arrest, many people are unsure what will happen next, how quickly they need to act, and what role a defense attorney actually plays in the process. In Ada County and other Idaho courts, cases typically move through an arraignment, preliminary hearing, and pretrial conferences before any trial date is set, which gives a defense team time to investigate the facts and assess the strength of the prosecutor’s case. A felony DUI lawyer Boise defendants hire can use this period to obtain police reports, body camera footage, and test records and to begin identifying weaknesses in the state’s evidence.

Common defense steps can include examining whether the traffic stop was lawful, challenging the way field sobriety tests were administered, and reviewing how breath or blood samples were collected, stored, and analyzed. In some situations, it may be appropriate to consult with toxicology or accident reconstruction professionals, especially when the case involves allegations of serious injury or vehicular manslaughter. By comparing what the law requires under Idaho statutes with what actually happened during the stop and investigation, your attorney can determine whether to file motions to suppress evidence, negotiate for reduced charges, or prepare the case for trial before a local jury.
