Makes it a federal crime to intentionally block a public road or highway when that action obstructs, delays, or otherwise affects commerce or the movement of goods. Violators may be fined, imprisoned for up to 5 years, or both; the change amends federal criminal law (18 U.S.C. §1951) and updates related cross-references in the U.S. Code.

The change targets conduct that interferes with interstate or other commercial movement on public roads and shifts a class of obstructive conduct into federal criminal jurisdiction, with potential enforcement and civil‑liberties implications.
