The Missouri State Legislature has introduced House Bill 1387, known as the "Alexander Whalen Safe Highways Act," aimed at enhancing road safety through the implementation of wrong-way vehicle detection systems (WWVDS). Proposed by Representative Keathley and introduced on February 19, 2025, the bill seeks to address the critical issue of wrong-way driving, which poses significant risks to motorists.

The bill outlines a comprehensive plan for the Department of Transportation to install WWVDSs by March 1, 2026. These systems will utilize radar sensors and thermal cameras to detect vehicles traveling in the wrong direction, coupled with illuminated "do not enter" signs and real-time alerts to traffic management centers and law enforcement. The initial focus will be on high-risk highway interchanges, starting with the intersection of westbound Interstate 64 and Jefferson Avenue, as well as other locations identified through crash and traffic data.

Key provisions of the bill include the integration of WWVDSs with dynamic message signs to provide immediate warnings to nearby drivers and a system to automatically notify emergency responders when a wrong-way driver is detected. This proactive approach aims to reduce the number of accidents caused by wrong-way driving, which has been a growing concern on Missouri highways.

While the bill has garnered support for its potential to improve road safety, it may face debates regarding funding and the prioritization of specific interchanges for installation. The economic implications of the bill could involve costs associated with the technology and infrastructure upgrades, but proponents argue that the long-term benefits of reducing accidents and saving lives outweigh these expenses.

As the bill progresses through the legislative process, its significance lies in its potential to transform highway safety measures in Missouri, reflecting a growing trend among states to adopt advanced technologies for traffic management. If passed, House Bill 1387 could serve as a model for other states looking to enhance their road safety initiatives.
