Rights of drunk driving accident victims in Montana

If a drunk driver hurt you or someone in your family, Montana law gives you a set of specific tools and, just as important, specific deadlines. The state carries one of the worst impaired-driving records in the country. In 2023 Montana's alcohol-impaired-driving fatality rate was 0.52 deaths per 100 million miles driven, well above the national rate of 0.38.¹ What follows is what Montana law actually says about your right to recover, with the statute numbers so you can check every point yourself.

The deadlines that decide your case

Montana gives you three years from the date of the crash to file a personal injury lawsuit.² If a drunk driver killed a member of your family, a wrongful death claim runs on the same three-year clock, with one exception: the window stretches to ten years when the death resulted from a homicide.² A fatal impaired-driving crash can be that homicide. Montana prosecutes it as vehicular homicide while under the influence when a driver negligently causes a death while operating a vehicle over the legal limit.³ Damage to property, including your vehicle, sits on a shorter two-year clock.⁴ These are hard cutoffs. File late and the court will almost always dismiss the case, no matter how plainly the other driver was drunk.

How Montana divides the blame

Montana uses modified comparative negligence. You can still recover as long as your share of the fault is not greater than the other side's, but once your fault reaches 51% you recover nothing.⁵ Whatever you win is reduced by your own percentage, so a $200,000 award with 10% of the blame on you pays $180,000. In a drunk driving case the rule usually cuts in the victim's favor. A driver who was over the limit carries most or all of the fault, and Montana's per se thresholds are strict: 0.08 blood alcohol concentration for adult drivers, 0.04 for commercial drivers, and 0.02 for anyone under 21.⁶ A reading at or above those numbers is itself the offense, which makes the impaired driver's negligence far easier to prove in your civil case.

Suing the driver and the punitive damages question

Montana puts no cap on the compensatory damages you can recover from an at-fault driver in an ordinary crash. Your medical bills, lost income, future care, and pain and suffering are all recoverable in full. Drunk driving cases open a second door: punitive damages, which exist to punish the driver rather than to compensate you. Winning them takes more proof. You have to show by clear and convincing evidence that the driver acted with actual malice or actual fraud, a heavier burden than the preponderance standard that governs the rest of the case.⁷ Someone who chose to drive while impaired can meet it, and a DUI conviction from the criminal case can carry over as strong evidence when you ask a civil jury for punitive damages. When they are awarded, Montana caps punitive damages at the lesser of $10 million or 3% of the defendant's net worth.⁸

When a bar or host shares the blame

Montana lets you reach past the driver to whoever supplied the alcohol, but the opening is narrow. Under the state's furnishing-alcohol statute, a bar, restaurant, or private host is liable only if it served someone who was already visibly intoxicated, served a minor, or forced the person to drink or tricked them into it.⁹ Serving a customer who later turns out to have been drunk is not enough on its own; the intoxication had to be apparent when the drink was poured. These claims carry deadlines and limits that do not apply to a suit against the driver. You must give the establishment written notice within 180 days, file within two years, and your noneconomic damages are capped at $250,000, with any punitive damages capped at a separate $250,000.⁹

Getting paid when the driver has little or no coverage

Montana requires only modest insurance: $25,000 per person and $50,000 per crash for injuries, plus $20,000 for property damage.¹⁰ A serious injury burns through those limits quickly, and the driver who caused a DUI crash may carry only the minimum or nothing at all. Your own policy is often where the real money is. Montana insurers have to include uninsured and underinsured motorist coverage that matches your liability limits unless you turned it down in writing, and once you reject it, the coverage stays off your renewals until you ask for it back in writing.¹¹ Pull your declarations page and look for UM/UIM. It can fill the gap the drunk driver's policy leaves, and it also applies when a drunk driver flees the scene and is never identified, because a hit-and-run driver counts as uninsured. Montana has no no-fault or PIP system and no required medical-payments coverage, so you are not boxed into a first-party benefit; you pursue the at-fault driver's liability insurer, and your own UM/UIM, for the full loss. If your car was repaired but is now worth less on resale, that lost value is its own claim, and diminished value in Montana covers how to pursue it.

The criminal case can pay you back too

The DUI prosecution runs on its own track, separate from your civil claim, and it can put money in your hands without a lawsuit. Montana law requires a sentencing court to order an offender to make full restitution to any victim who suffered a financial loss.¹² That covers out-of-pocket costs like medical bills and vehicle damage, and it is mandatory, not left to the judge's discretion. Restitution usually will not reach pain and suffering, and it does not replace a civil suit, but it is a real recovery. Ask the county attorney handling the DUI to document your losses so they go into the sentence.

Practical first moves

Get the crash report early. The investigating agency in Montana is often the Montana Highway Patrol, and you can request yours through crash reports in Montana. Watch the calendar, because the three-year injury deadline, the two-year property and dram-shop deadlines, and the 180-day dram-shop notice all run from close to the date of the crash. And because these cases often involve punitive damages, more than one insurer, and short windows to act, it is worth talking with a Montana attorney early. You can find one through the legal directory.
