PrePass Safety Alliance is a non-profit public/private partnership formed to improve highway safety and efficiency. Both PrePass Safety Alliance and its PrePass service can trace their origins to a multi-year truck safety demonstration program that began in the mid-1980s. The demonstration program was known as the Crescent Project, in which innovative state DOT directors and trucking executives sought a way to pre-screen and weigh qualified, safe commercial trucks at highway speeds, providing efficiencies to both the trucking industry and state enforcement agencies.
The Crescent Project involved the states of Arizona, California, New Mexico, Oregon, Texas and Washington, and the province of British Columbia. The results of the Crescent Project ultimately led to the creation of The Alliance and the launch of the PrePass service. Today, The Alliance’s PrePass e-screening and weigh station bypass, coupled with its PrePass Plus toll management system, represent not only North America’s largest truck safety pre-clearance service but also the nation’s largest vehicle-to infrastructure (v2i) program.
