About this file
This document is the California Department of Transportation (Caltrans) Authorized Materials List for Highway Safety Features, effective May 18, 2026, which serves as the approved product catalog for highway crash safety installations across all Caltrans districts. The list encompasses four primary categories of safety products: crash cushions (16 approved products from manufacturers including Lindsay Transportation Solutions, Valtir LLC, TrafFix Devices, and others), end terminals (11 approved products), permanent and temporary barriers (13 approved products), and truck and trailer-mounted attenuators (13 approved products), along with miscellaneous safety components including composite blocks and breakaway systems. Each product is designated for specific applications including permanent, temporary, narrow, wide, flared, inline, and median configurations, with traffic level (TL) ratings ranging from TL-1 to TL-4. The list also identifies products approved under the 350 standard or MASH (Movable Barrier and Roadside Safety Hardware) protocol, with reauthorization dates extending through April 2028.
The authorized materials list reflects Caltrans' implementation of the Build America, Buy America Act (BABA) statutory requirements mandated by the Bipartisan Infrastructure Law. BABA Act information provided for each product specifies domestic content requirements, including products manufactured with steel and iron melted and fabricated in the United States, manufactured products with 55 percent or higher domestic cost content and final assembly in the US, or products classified as excluded materials per 2 CFR 184.3. Multiple manufacturers are represented on the list, with no single vendor dominating any product category, allowing for competitive procurement. All listed products have been verified by manufacturers as meeting applicable standards. Reference materials including MASH implementation details, vendor drawings, product approval memos, OCCS standards, standard plans, and bridge standard details are accessible through the Caltrans website for specification and implementation guidance.
