Deadly wrong-way crashes are climbing across Nevada, and state officials are in a race against the clock to stop drivers before they slam into freeway traffic. UNLV researchers say the trend is especially alarming because so many of these incidents happen at highway speeds and often kill more than one person in a single hit. With construction and system testing already under way on key Las Vegas Valley freeways, state transportation leaders are betting that a mix of sensors, flashing “Wrong Way” signs and control-room software can blunt some of the worst outcomes.
According to a new TREND newsletter from UNLV’s Traffic Safety Research Group, 38 fatal wrong-way crashes killed 57 people statewide between 2017 and 2024, with Clark County accounting for 23 of those crashes. When toxicology tests were conducted, substance involvement was common, and in some years 60–100% of tested wrong-way drivers showed signs of alcohol or drugs. The researchers also found that 2024 recorded the highest number of fatal wrong-way crashes in the series so far.
“The trend on this data is that it’s increasing,” said Dr. Deborah Kuhls, UNLV’s trauma chief and co‑author of the analysis, stressing that many of these crashes are head‑on collisions at freeway speeds. Her comments, and the topline findings from the report, were highlighted in coverage by KSNV.
NDOT Maps Out New Alerts On I‑11 And The 215
State transportation officials are rolling out more electronic wrong‑way alert systems across the Las Vegas Valley, plotting 12 new detector-and-sign pairs on I‑11/US‑95 along with additional setups on the 215, FOX5 reports. The station also pointed to NDOT’s earlier pilot project, which ran from 2020 to 2022 and found that roughly 84% of drivers turned around after being confronted with the flashing “Wrong Way” warnings.
New Signs Up And Under The Microscope On The 215
The Nevada Department of Transportation says crews have finished installing wrong‑way alert systems on westbound I‑215 off‑ramps to Las Vegas Boulevard, Warm Springs Road and Windmill Lane, and recently used overnight closures in May to test and calibrate the new gear, according to a department news release. NDOT describes the setup as radar and camera sensors that detect a vehicle entering a ramp in the wrong direction, then trigger flashing “Wrong Way” signs while simultaneously notifying traffic operators and law enforcement.
Do The Flashing Warnings Actually Turn Drivers Around?
Early tracking suggests the alerts are doing their job more often than not. NDOT validated 28 wrong‑way driver events between July 1, 2024 and June 30, 2025 and reported that 21 of those drivers turned around after the warning signs lit up, FOX5 reports. Safety researchers, however, are quick to point out that this technology is meant to be a last line of defense, not a free pass for risky behavior. The UNLV analysis found impaired driving remains the leading risk factor behind these deadly wrong‑way runs.
What’s Next On Nevada’s SafeTech Corridor
Construction on the I‑11 SafeTech Corridor kicked off May 31, 2026. The roughly $22 million program will add active‑traffic‑management gantries, two wrong‑way detection systems at six interchanges and several strategic traffic‑management sites designed to speed up incident response, according to the Nevada Department of Transportation. Researchers and safety advocates say those tools can save lives when they work as intended, but they also stress that cutting impaired driving and boosting enforcement are still critical pieces of preventing future wrong‑way tragedies, as UNLV’s Traffic Safety Research Group notes.
