Senate File No. 728 is a legislative bill introduced to increase the penalties for obstructing traffic on major roads such as highways, airports, or transit routes. The bill essentially modifies existing laws by classifying the act of intentionally blocking traffic on these roads as a gross misdemeanor. This is an upgrade from the current classification as a misdemeanor.

The categories of roads covered include freeways (defined as divided highways with controlled access via ramps) and roads within airport boundaries, specifically those with control towers and airline services. The increased penalties do not apply to law enforcement, emergency responders, road or airport authorities, or utility officials performing their duties legally.

In summary, this bill aims to deter disruptions on major transportation routes by imposing stricter consequences for those who obstruct traffic intentionally.
