Keep Drivers Safe with Great Wrong Way Signs
Wrong-way driving is rare, but when it happens, it turns an exit ramps or one-way street into a split-second decision zone. Here at National Sign & Signal, we focus on traffic safety equipment that helps agencies reduce risk before it becomes a headline, and you can start exploring our many options when searching through our site.
In this month’s blog, we’re highlighting the VADS “Wrong Way” Alert System, a vehicle alert detection system designed to detect and deter vehicles entering a highway, one-way street, or even a railroad crossing from the wrong direction or at a restricted time.
Why Wrong Way Prevention Needs More Than a Standard Sign
Traditional “WRONG WAY” signs matter, but signage alone cannot always catch an impaired, distracted, or unfamiliar driver at the exact moment they commit. That’s where roadway security tools and access control systems come in, especially for high-risk locations where an early warning can buy precious reaction time.
How VADS Helps Agencies Detect, Alert, and Deter
VADS uses intelligent, microprocessor-controlled radar motion sensors and traffic control equipment to identify and track misdirected traffic in real time, then trigger visual and audio warnings when user-defined rules are violated. Depending on the configuration, alerts can include flashing LED strobe lights, internally illuminated case signs, LED or fiber-optic blank-out signs, and siren/horn signals.
VADS can also broadcast alerts via ethernet radio, cellular, or satellite communication to notify authorities, and it can be powered by a 24-volt system charged by standard 110VAC or solar power.
Where It Fits Best
If you’re mapping out a roadway safety upgrade, these are common places where wrong-way detection and deterrence can make a big difference:
- Exit ramps and interchanges with a history of driver confusion
- One-way streets near downtown districts or event venues
- Restricted access roadways
- Rural intersections where visibility and lighting are limited
- Railroad crossings with specific access rules or seasonal traffic patterns
National Sign & Signal also offers a broader set of security products aimed at perimeter security, intelligent area denial, and protecting critical infrastructure. If you’re evaluating options, our team can help you match the right system to your site conditions and safety goals, just contact us!
