Which of the following is NOT an objective of MAP-21?

Answer: A — Roadside inspections

MAP-21, which stands for the Moving Ahead for Progress in the 21st Century Act, was a significant piece of U.S. legislation aimed at improving surface transportation infrastructure. While it includes various objectives related to enhancing transportation systems and safety, roadside inspections specifically fall within the realm of compliance and enforcement rather than a primary objective of this act. The main goals of MAP-21 are more focused on maintaining infrastructure quality, protecting environmental resources, and reducing traffic congestion. Maintaining infrastructure conditioning aligns with the act's emphasis on preserving and improving the nation's roads and bridges. Protecting the environment is also an objective, as MAP-21 encourages projects and practices that minimize environmental impact. Reducing traffic congestion is critical for improving the efficiency of transportation systems, which MAP-21 addresses through funding for various infrastructure improvements and operational strategies. Roadside inspections, while important for policy enforcement and safety checks within the trucking industry, do not represent a core objective of MAP-21, which is why this choice stands apart from the others that are more closely aligned with its legislative goals.
