A Las Vegas woman died after the SUV she was riding in slammed into a barrier wall on Brent Thurman Way early Saturday morning, and the driver was arrested at the scene on suspicion of impairment. Haely Brooke Polaski was pronounced deceased at a local hospital after being transported there in critical condition, according to hospital personnel. The crash happened around 5:50 a.m. just south of West Hacienda Avenue in Clark County.
According to FOX5 Las Vegas, a dark green Genesis GV80 was traveling northbound on Brent Thurman Way in the number one travel lane when, per the preliminary investigation, the driver failed to maintain the travel lane and overcorrected to the left. The SUV then struck an unknown barrier wall with its left front. Polaski, who was riding as a passenger, was unrestrained at the time of the crash and was transported to a local area hospital, where she later succumbed to her injuries, per hospital personnel. The Nevada Highway Patrol, a division of Nevada State Police, responded to the scene and arrested the driver on suspected impairment.
A Road With a Troubled Safety History
Brent Thurman Way is a frontage road that runs parallel to the Bruce Woodbury Beltway, or CC-215, through the Spring Valley area, connecting commercial office parks and business plazas between Sunset Road and Tropicana Avenue. The corridor has seen fatal crashes before: in November 2015, a 77-year-old man was killed in a hit-and-run along the same stretch near West Hacienda Avenue, which drew attention from nearby office workers who cited high vehicle speeds as drivers merge toward the Beltway's freeway ramps.
The road itself carries a somber namesake. It was named in 2008 for Brent Cullen Thurman, a 25-year-old professional bull rider who died in December 1994 from severe cranial injuries sustained during the National Finals Rodeo in Las Vegas. Thurman remains the only competitor to suffer a fatal injury in the history of the NFR.
What Nevada Law Says About Impaired Driving Deaths
If the driver is ultimately charged and convicted of DUI resulting in death, Nevada law treats the offense with unusual severity. Under Nevada Revised Statute 484C.430, driving under the influence resulting in death or substantial bodily harm is a Category B felony punishable by 2 to 20 years in state prison, with mandatory fines between $2,000 and $5,000. State law strictly bars probation or suspended sentences for that conviction.
The passenger's lack of a seat belt sits in a different legal category entirely. Under Nevada Revised Statute 484B.157, adult seat belt violations are secondary offenses carrying a fine of up to $25 or community service, and officers cannot stop a vehicle solely because an occupant is unbelted. The distinction underscores how Nevada law separates a driver's potential criminal liability from a passenger's own restraint choices.
A Broader Pattern of Lane-Deviation Crashes
The crash echoes another case Hoodline has covered this year involving impairment and an unrestrained occupant. In a Clark County grand jury indictment tied to Valley of Fire, a Nevada Highway Patrol investigation similarly centered on a failure-to-maintain-lane charge following a fatal I-15 crash that killed an unrestrained passenger.
Statewide, traffic fatality numbers have been trending downward. Clark County recorded 239 traffic fatalities in 2025, a 19 percent drop from 296 deaths in 2024, with occupant deaths within the county falling 29 percent to 85 fatalities, according to the Las Vegas Review-Journal. Nevada as a whole logged 380 traffic deaths in 2025, down 9.5 percent from 420 the year before, marking the first time since 2021 that the statewide total fell below 400.
More recent figures show a mixed picture. Nevada registered 26 unrestrained vehicle occupant deaths in the first half of 2026, a 25.71 percent decrease from the 35 recorded over the same period in 2025, per the Nevada Independent's reporting on state data. Yet the Nevada Office of Traffic Safety's own numbers show that while the state saw a 16.17 percent overall decrease in fatalities through May 2026 compared with the prior year, May 2026 alone saw 32 deaths — a 14.29 percent increase over May 2025.
Nevada's 2026–2030 Strategic Highway Safety Plan sets a goal of cutting fatal and serious injury crashes by 35 percent statewide by 2035, with an ultimate target of zero traffic deaths by 2050. Whether infrastructure or barrier visibility played any role in Saturday's crash on Brent Thurman Way has not been addressed by investigators, and formal charges against the driver had not been detailed as of this report.
