When Tragedy Strikes: Understanding Montana’s Toughest DUI Law
If you’re facing charges related to a fatal DUI incident in Montana, you’re confronting one of the most serious legal situations imaginable. The weight of what has happened, combined with the reality of Montana’s Bobby’s Law and its mandatory 3-year minimum sentence, can feel overwhelming. This law, which was enacted in 2025 (signed by the governor on April 25, 2025), fundamentally changed how Montana prosecutes certain fatal DUI cases by creating a new aggravated vehicular homicide-while-under-the-influence offense that carries a mandatory minimum three-year prison term for offenders meeting the law’s criteria (for example, a BAC of at least 0.16 or those under certain court-ordered DUI restrictions). Understanding your rights and the legal landscape you’re navigating becomes crucial not just for your defense, but for your future.
💡 Pro Tip: If you’re facing any DUI-related charges, document everything you remember about the incident immediately, including road conditions, weather, and any mechanical issues with your vehicle – these details can be crucial for your defense strategy.

Your Constitutional Rights Under Bobby’s Law
Bobby’s Law represents a significant shift in Montana’s approach to fatal DUI cases, but it doesn’t strip away your fundamental constitutional rights. Every person charged under this law retains the right to a vigorous defense, the presumption of innocence, and the requirement that prosecutors prove guilt beyond a reasonable doubt. When working with a DUI lawyer in Montana, understanding these rights becomes your first line of defense against the mandatory minimums this law imposes. The law specifically targets aggravated vehicular homicide while under the influence, applying when a driver causes a death and meets the aggravated-DUI criteria—most commonly a blood alcohol concentration of .16 or higher or when the driver is subject to certain court or licensing restrictions related to prior DUIs—rather than broadly applying to all cases of drug impairment.
The HB 267 Bobby’s Law DUI legislation was named after Robert "Bobby" Dewbre, a 21-year-old who was killed by a drunk driver; the driver was sentenced to 18 months in county jail. This personal tragedy sparked a statewide movement that resulted in mandatory sentencing requirements designed to ensure consistency in punishment across Montana’s courts for qualifying aggravated cases. However, the law’s rigid structure also means that factors which might have previously led to reduced sentences – such as lack of prior offenses, remorse, or extenuating circumstances – no longer carry the same weight in sentencing decisions for those aggravated offenses.
💡 Pro Tip: Request copies of all police reports, witness statements, and blood/breath test calibration records immediately – delays in obtaining these documents can impact your ability to identify procedural errors or inconsistencies in the prosecution’s case.
The Legal Process: What to Expect After a Fatal DUI Charge
Understanding the timeline of a fatal DUI case under Bobby’s Law helps defendants and their families prepare for what lies ahead. The process typically unfolds over several months, with each stage presenting opportunities for legal advocacy and defense strategy development. Having an experienced DUI lawyer in Montana guide you through each phase becomes essential, especially given the mandatory minimum sentences at stake.
- Initial arrest and booking, including blood or breath testing at the direction of a peace officer in fatal DUI investigations; Montana law uses a "reasonable time" standard for when tests must be taken rather than a strict two-hour deadline
- Arraignment within 10 days, where formal charges are read and initial plea entered
- Discovery phase lasting 30-90 days, during which evidence is exchanged between prosecution and defense
- Pre-trial motions addressing constitutional issues, evidence suppression, or procedural violations (typically 60-120 days post-arraignment)
- Plea negotiations, though limited by mandatory minimums for the aggravated offense, may still address charge reductions or concurrent sentencing
- Trial preparation and jury selection if no plea agreement is reached (6-12 months from initial charges)
- Sentencing phase, where the 3-year mandatory minimum applies if convicted of the aggravated vehicular homicide-while-under-the-influence offense and the statutory criteria are met
💡 Pro Tip: Keep a detailed journal of all court dates, meetings with your attorney, and any communication with law enforcement or prosecutors – this documentation can help identify timeline violations or procedural errors that might benefit your defense.
Defense Strategies: How a DUI Lawyer in Montana Can Help Navigate Bobby’s Law
While Bobby’s Law establishes harsh mandatory minimums for qualifying aggravated cases, effective legal representation remains crucial in fatal DUI cases. The attorneys at Tipp Coburn Lockwood P.C. understand that challenging the underlying evidence, questioning procedural compliance, and exploring alternative charge structures can make the difference between facing mandatory minimums and achieving more favorable outcomes. Even with mandatory sentencing guidelines for the aggravated offense, skilled legal advocacy can address charge reductions, concurrent sentencing arrangements, or identify constitutional violations that might lead to case dismissal.
The complexity of fatal DUI cases demands thorough investigation of every aspect of the incident. This includes examining blood alcohol testing procedures, chain of custody for evidence, accuracy of field sobriety tests, and potential mechanical failures or road hazards that contributed to the accident. A DUI lawyer in Montana experienced with Bobby’s Law cases knows that the prosecution must prove not just impairment, but that impairment was the proximate cause of the fatal accident – a distinction that can be crucial in building an effective defense.
💡 Pro Tip: Never discuss your case on social media or with anyone except your attorney – even seemingly innocent posts or conversations can be used as evidence against you in court.
The Human Cost: Understanding the Broader Impact of Fatal DUI Cases
Fatal DUI incidents create ripple effects that extend far beyond the courtroom. Families on all sides face emotional trauma, financial hardship, and long-lasting consequences. Understanding these impacts helps defendants and their families prepare for the challenges ahead while working with a DUI lawyer in Montana to address both legal and personal ramifications. Insurance claims, civil lawsuits, and professional license suspensions often accompany criminal proceedings, creating a complex web of legal issues requiring comprehensive representation.
Financial and Professional Consequences
Beyond the criminal penalties imposed by Bobby’s Law, defendants face substantial financial burdens. These may include restitution to victims’ families, which can reach hundreds of thousands of dollars, loss of professional licenses in fields like healthcare or transportation, and inability to maintain employment while incarcerated. The Traffic Safety Trends State Legislative Action 2023 report does not make the claim that states with mandatory minimum sentences for fatal DUIs often see defendants facing combined criminal and civil judgments exceeding $500,000; however, individual civil wrongful-death and punitive-damage awards in fatal DUI cases can and do exceed $500,000, making early legal intervention critical for protecting assets and planning for financial obligations.
💡 Pro Tip: Consult with your attorney about asset protection strategies early in your case – waiting until after conviction severely limits options for managing financial exposure from civil lawsuits and restitution orders.
Challenging Evidence in Fatal DUI Cases
Success in defending against charges under Bobby’s Law often hinges on challenging the prosecution’s evidence at every level. Modern DUI cases involve complex scientific evidence, from blood alcohol testing to accident reconstruction, each presenting opportunities for skilled legal challenge. Working with a DUI lawyer in Montana who understands these technical aspects can reveal weaknesses in the state’s case that might otherwise go unnoticed.
Blood Alcohol Testing and Chain of Custody
Montana law requires strict protocols for blood alcohol testing, including proper storage, handling, and analysis procedures. Delays in testing, improper storage temperatures, or breaks in the chain of custody can all impact test reliability. Additionally, certain medical conditions, medications, or even dietary factors can affect blood alcohol readings, creating reasonable doubt about actual impairment levels at the time of the incident.
💡 Pro Tip: Request detailed maintenance records for all testing equipment used in your case – even minor calibration issues or missed maintenance schedules can cast doubt on test accuracy.

Understanding Your Rights and Options

💡 Pro Tip: Write down all your questions before meeting with an attorney – the stress of your situation can make it easy to forget important concerns during consultations.

1. What exactly does Bobby’s Law require in terms of sentencing for fatal DUI cases?
Bobby’s Law mandates a minimum 3-year prison sentence for anyone convicted of the new aggravated vehicular homicide-while-under-the-influence offense in Montana when the offender meets specified criteria (for example, a BAC of at least 0.16 or being under certain court-ordered DUI restrictions). Judges cannot defer or suspend that minimum for the aggravated offense, but the law does not impose that three-year floor on all vehicular-homicide convictions.
2. Can a Missoula Montana DUI attorney help reduce charges even with mandatory minimums?
Yes, skilled attorneys can potentially negotiate for reduced charges that don’t trigger mandatory minimums. This might include challenging whether impairment was the direct cause of death, negotiating for lesser charges like negligent homicide, or identifying procedural errors that weaken the prosecution’s case. Each case requires individual analysis of evidence and circumstances.
3. How do Montana DUI laws differ from neighboring states regarding fatal accidents?
Montana’s Bobby’s Law establishes one of the strictest mandatory minimums in the region for qualifying aggravated cases. While states like Idaho and Wyoming generally allow judicial discretion in sentencing for fatal DUI cases, Montana requires the 3-year minimum for the aggravated offense when the statutory criteria are met.
4. What happens to my driver’s license if I’m charged under Bobby’s Law?
License suspension typically occurs immediately upon arrest for fatal DUI, separate from criminal proceedings. Montana law allows for administrative suspension before any conviction, though you have the right to challenge this through administrative hearings. Montana law requires revocation of driving privileges for convictions like negligent homicide or vehicular homicide, but revocations are for specified durations (commonly one year) rather than automatically permanent; restricted or probationary driving privileges may be available only in limited, conditional circumstances (for example, court recommendation, enrollment in 24/7 programs, use of an ignition interlock device, and compliance with statutory waiting periods).
5. Should I accept a plea deal if I’m facing charges under fatal DUI penalties Montana?
This decision requires careful analysis with your attorney. While Bobby’s Law limits sentencing flexibility for the aggravated offense, plea negotiations might address charge reductions, concurrent sentencing for multiple charges, or agreements on restitution amounts. Your attorney should thoroughly review evidence strength, potential defenses, and likely trial outcomes before advising on plea decisions.
