California to spend $2.4 million on commercial vehicle ‘e-screening’ and Weigh-In-Motion at three locations along key freight corridors
The California Department of Transportation (Caltrans) will move ahead with three new projects to add commercial vehicle monitoring technology along key freight corridors.
On March 31, 2026, commercial vehicle compliance technology company Quarterhill Inc. announced that it was awarded three Caltrans contracts worth approximately $2.4 million.
Quarterhill provided details on the three commercial vehicle e-screening and Weigh-In-Motion (WIM) technology projects. See below.
- Desert Hills Commercial Vehicle Enforcement Facility (Riverside County) – Deployment of a commercial vehicle e-screening system designed to support more efficient enforcement operations by allowing California Highway Patrol officers to focus inspections on vehicles that may be non-compliant while enabling compliant trucks to move more efficiently through the facility. This will improve enforcement efficiency while reducing congestion at inspection facilities
- Interstate 10 WIM Data Collection System (San Bernardino County) – Installation of a WIM data collection system that will provide detailed vehicle weight and traffic data used to support infrastructure monitoring, freight planning, and transportation system performance analysis. Installation of the system is expected to begin in late 2026 and includes a six-year warranty.
- Route 805 WIM Expansion (San Diego County) – Expansion of WIM coverage along a major freight corridor to enhance the availability of commercial vehicle weight and traffic data used to support transportation planning and infrastructure monitoring across the California’s highway network.
Quarterhill says that these three projects will provide data for better transportation planning as well as allowing for “more targeted enforcement by the California Highway Patrol by helping identify vehicles that may require inspection while allowing compliant trucks to move more efficiently through key freight corridors.”
“California operates one of the largest and most complex freight transportation networks in North America and continues to lead the way in using technology to make its highways safer and more efficient,” said Chuck Myers, CEO of Quarterhill. “We are proud to expand our long-standing partnership with Caltrans by delivering the data and screening solutions that help identify high-risk vehicles, streamline compliant truck movement, and support safer highways and infrastructure planning across California’s transportation network.”
