Second Offense DUI

Second Offense DUI Lawyer in Boise

Idaho’s DUI-Focused Defense Firm. Trial Included, Flat-Rate Fee.

A second DUI charge within 10 years of a prior conviction puts you in a different category under Idaho law. Mandatory minimum penalties apply, and a judge can’t go below them regardless of the circumstances. The window to challenge the charge before sentencing is locked in is narrow, and it opens the moment you’re arrested.

Idaho Legal Justice focuses on DUI defense. Our attorneys know Idaho Code section 18-8005, Ada County prosecution patterns, and how second-offense cases move through Boise courts. When you call us, you reach attorneys directly. Clients get attorney cell phone numbers, and our flat-rate fee covers trial at no additional cost if your case needs to go that distance.

From the first call, we work to set you up with a DUI evaluation, alcohol classes, and a Victim’s Panel as part of building the strongest possible case. When legal defenses exist, we fight for a fair outcome and take the case to trial. Free consultations are available.

Penalties for a Second Offense DUI in Idaho

Nearly every penalty for a second DUI is steeper than a first offense, and some are mandatory regardless of what a judge might otherwise decide.

Jail, Fines, & Felony Escalation

A standard second DUI within 10 years is a misdemeanor under Idaho Code section 18-8005, carrying a mandatory minimum of 10 days in jail up to one year and a maximum fine of $2,000, along with additional penalties and fees. Mandatory minimums mean exactly what they say: a judge can’t sentence below them, which is why challenging the charge before conviction is the only way to avoid them.

If your prior DUI involved a BAC of 0.20 or higher and your current offense also involves a BAC of 0.20 or higher, and that prior offense occurred within the past five years, the charge escalates to a felony under Idaho Code section 18-8004c. A felony DUI charge carries 30 days to five years in prison and fines up to $5,000. Felony DUI outcomes depend heavily on the specific facts, and speaking with one of our attorneys can help you understand what you’re facing.

Will I Lose My License?

Yes, and the suspension is more severe than on a first offense. Idaho law imposes a one-year absolute suspension of driving privileges for a second DUI conviction.

Unlike a first offense, where you can apply for limited driving privileges, that option doesn’t typically exist for a second offense**. Once the suspension ends, you’ll be required to have an ignition interlock device installed on all vehicles you operate for an additional year before full reinstatement. Higher auto insurance rates and SR-22 filing requirements kick in after reinstatement and can extend the financial impact well beyond the suspension period.

**If you are a resident of Canyon County and your DUI occurred in Canyon County, you may have the option of applying for DUI Court, which could allow you to apply for a restricted license. For more information, contact our office and talk to one of our attorneys.

Will I Have a Permanent Criminal Record?

If you are convicted, a second DUI conviction becomes a permanent part of your criminal record. It stays there unless overturned.

The consequences reach well beyond the courtroom. A second DUI can affect eligibility for jobs that require driving, professional licenses in fields like healthcare or finance, and security clearances. A prior conviction within 10 years also becomes the foundation for enhanced penalties if another DUI occurs in the future.

How We Defend Second Offense DUI Cases in Boise

Mandatory minimums don’t mean mandatory conviction. Before any resolution is reached, our attorneys conduct a thorough review of the state’s case to identify weaknesses that can affect the outcome. We exhaust every available defense before considering a negotiated resolution.

Challenging the Evidence

Defense angles in Idaho second DUI cases include questioning whether the traffic stop was lawful, contesting how field sobriety tests were administered and scored, examining breath machine calibration records and operator certification, and scrutinizing blood draw chain of custody. A successful suppression motion can exclude key evidence and alter the entire trajectory of a case, even where mandatory sentencing would otherwise apply. Ada County prosecutors on second-offense cases are typically less willing to negotiate than on first offenses, which makes a thorough pre-trial investigation more critical, not less.

When legal defenses exist, we fight for a fair outcome and take the case to trial at no additional cost. That’s what our flat-rate model means in practice: the decision to go to trial is made on the merits of your case, not on what you can afford.

The Seven-Day Administrative License Deadline

A DUI arrest triggers two separate proceedings: the criminal case and an administrative license suspension through the Idaho Transportation Department. These aren’t the same process, and missing the administrative deadline forfeits rights that can’t be recovered later.

After a second-offense DUI arrest in Boise, you have seven days to request a hearing to contest the administrative suspension. Missing that deadline means the one-year absolute suspension takes effect without any opportunity to challenge it separately. Our attorneys coordinate the license defense with the criminal case strategy from day one so the two reinforce each other rather than working at cross-purposes.

What a Second DUI Conviction Costs Beyond the Courtroom

The penalties listed in Idaho Code section 18-8005 are the starting point, not the full picture. A second DUI conviction carries consequences that follow you long after the sentence is served.

How a second DUI conviction affects your life beyond the courtroom:

Employment in any role that requires driving or a clean background check can be affected.
Professional licenses in healthcare, law, education, and finance may be subject to review or revocation.
Commercial driver’s license holders face separate federal disqualification rules that can apply even when the DUI occurred in a personal vehicle.
Auto insurance rates increase significantly after a second DUI, and SR-22 filing requirements extend for years after reinstatement.
A second conviction within 10 years strengthens any future enhancement to felony-level charges if another DUI occurs.

How this case resolves matters far beyond the courtroom. A more favorable outcome can limit how much it follows you.
