WisDOT Implements Advanced Detection Technology to Combat Wrong-Way Crashes
Madison, Wis. — December 12, 2025
The Wisconsin Department of Transportation (WisDOT) is taking decisive action against the dangers posed by wrong-way driving incidents with the rollout of expanded detection and alert systems across the state. As part of a comprehensive statewide safety initiative, officials are deploying sophisticated technology designed to detect and warn drivers who mistakenly enter freeways and divided highways in the wrong direction, aiming to prevent potentially catastrophic crashes.
Addressing a Persistent Safety Challenge
Wrong-way crashes, though relatively rare, are disproportionately severe, often involving multiple vehicles traveling at high speeds. According to Brian Porter, traffic engineering and safety section chief at WisDOT, these incidents have long been an ongoing concern.
“These crashes are very tragic and typically severe, affecting multiple drivers,” Porter explained. He highlighted that data consistently shows a majority of wrong-way crashes occur during late-night hours and frequently involve impaired drivers.
Porter further emphasized the gravity of these events, noting that while representing only about one to two percent of the state’s total traffic fatalities, wrong-way crashes tend to result in a higher rate of fatal outcomes.
New Detection and Alert Systems in Key Locations
As part of the latest efforts, WisDOT has recently installed 10 additional wrong-way driver alert systems statewide. Three new systems have been positioned in Dane County, with strategic placements along the Beltline, near East Washington Avenue and Highway 30, and in the Middleton area.
The new systems utilize a combination of radar technology and cameras. As a vehicle approaches an on-ramp, if it begins traveling the wrong way, the radar detects the movement and the camera immediately confirms the violation. The driver then sees multiple, highly visible warnings including oversized "Do Not Enter" signs, large "Wrong Way" signs, and LED-lit borders surrounding these signs to attract attention.
Concurrently, the technology alerts WisDOT’s traffic management center and local law enforcement. This rapid response capability enables officials to warn other motorists through dynamic message boards on nearby freeways and dispatch emergency responders promptly.
Collaboration Between Engineering and Driver Responsibility
While infrastructure improvements are a critical component, Porter acknowledged that driver behavior remains central to preventing wrong-way crashes.
“WisDOT is enhancing how we engineer our roadways to minimize risk, but ultimately, the responsibility lies with drivers,” Porter said. “We need everyone’s cooperation. Drivers should always remain sober, buckle up, avoid distractions like phones, and carefully follow traffic signs.”
What Drivers Should Do If They Encounter a Wrong-Way Vehicle
Authorities urge motorists to take immediate precautions if they encounter a vehicle traveling the wrong way:
- Exercise caution and reduce speed.
- Safely move your vehicle away from the wrong-way driver, moving to the right or off the road if possible.
- Call 911 promptly and report the driver’s location.
Upon receiving reports or detecting wrong-way drivers, WisDOT can activate traffic cameras positioned along state highways to monitor the situation and use dynamic message signs to alert other drivers in real-time.
Ongoing Monitoring and Future Enhancements
WisDOT officials continue to review crash data to identify high-risk locations and evaluate where additional detection systems can be introduced. Through these combined efforts in technology deployment and public awareness, the department aims to reduce the incidence and severity of wrong-way crashes throughout Wisconsin.
