What organization did FMCSA assume regulatory authority over chassis operations from?

The Federal Motor Carrier Safety Administration (FMCSA) assumed regulatory authority over chassis operations from the Federal Highway Administration (FHWA). This transition occurred as part of a broader effort to enhance safety and compliance in the realm of commercial motor vehicle operations. The FMCSA's role focuses on the oversight of various vehicle operations, including those that involve chassis used in transporting goods.

Understanding this transition is crucial for grasping how regulations surrounding motor carrier safety have evolved. The FHWA had previously been responsible for a range of highway and vehicle regulations; however, as the FMCSA developed a more specialized focus on safety within the commercial motor vehicle sector, it became necessary to centralize authority under the FMCSA for improved oversight and enforcement in these areas. This realignment helps ensure a more unified and effective regulatory framework that specifically addresses the complexities of chassis operation in the context of commercial transportation on highways.
