This legislation seeks to significantly reduce bridge strikes by commercial motor vehicles through a multi-faceted approach. It mandates the Secretary of Transportation to establish a bridge clearance strike working group composed of diverse stakeholders, including federal agencies, trucking organizations, and GPS producers. This group will develop recommendations to enhance public-private data sharing, improve GPS navigation tools with specific commercial vehicle information, and address potential liability issues related to data accuracy. Following these recommendations, the Secretary must issue regulations to implement the proposed improvements. The bill also calls for a national education campaign to raise awareness among commercial drivers and establishes a national clearinghouse for bridge and tunnel clearance strike data, modeled after a National Cooperative Highway Research Program prototype. This clearinghouse will serve as a central repository for data collection, management, and dissemination of best practices for prevention. Furthermore, the legislation creates a grant program to fund research by eligible entities, such as State DOTs and local governments, aimed at identifying and analyzing infrastructure improvements to mitigate bridge strikes. These grants will also assess the effectiveness of current and future countermeasures. A key provision grants GPS administrators immunity from liability for injuries resulting from government-provided clearance height information.
