Setting Standards that Empower an Efficient, Secure Supply Chain
Our mission is simple: Promote, advance, and improve the welfare and interests of the motor carrier industry. We do this through research, education, lobbying and developing industry standards and best practices. Our goal is to have the most informed membership to not only grow profitably, but efficiently run operations and protect against new challenges resulting from the digital era.
