What is the primary difference between intra and interstate driving?

The primary difference between intra and interstate driving lies in the definition of the terms themselves. Interstate driving refers specifically to transportation that crosses state lines, while intrastate driving occurs within a single state's borders.

In this context, the correct answer emphasizes that interstate driving involves not just crossing state lines but also often includes delivering cargo across state borders. This distinction is vital because it determines the regulatory requirements that apply to drivers and their vehicles, including the level of certification needed and the governing authorities.

Intrastate transport is solely regulated by state laws, while interstate transport is governed by federal regulations, making understanding this difference critical for compliance with FMCSA guidelines. Always remember that interstate transportation typically encompasses broader regulatory oversight due to its inter-jurisdictional nature, which requires additional certifications and adherence to both federal and state regulations.
