The vehicles can transport a cargo at less cost than can shorter combinations because fewer tractors and drivers are needed and less fuel is used. This testimony focuses on three longer combination vehicle issues: (1) the economic impact on infrastructure--pavements, bridges, and interchanges--that result from expanded longer combination vehicle operations; (2) the potential benefits from and industry's use of longer combination vehicles; and (3) the safety of longer combination vehicle use. https://www.govinfo.gov/content/pkg/GAOREPORTS-T-RCED-94-306/html/GAOREPORTS-T-RCED-94-306.htm GAO/T-RCED-94-306 https://www.govinfo.gov/app/details/GAOREPORTS-T-RCED-94-306 Testimony GAO/T-RCED-94-306; Longer Combination Vehicles: Potential Infrastructure Impacts, Productivity Benefits, and Safety Concerns; Trucking operations Freight transportation operations Transportation research Safety regulation Highway safety Cost control Transportation costs Transportation safety Shipping industry Traffic regulation
