A bill for an act relating to the carrying, transportation, and possession of weapons, and including effective date provisions.

This bill modifies Iowa's gun laws in three key areas. It allows concealed firearms in locked vehicles within publicly accessible parking lots (like those at government buildings) when unoccupied, with exceptions for National Guard facilities. It explicitly prohibits rules that would ban firearms in vehicles transporting foster children. Additionally, it creates "weapons free zones" around schools and public parks, imposing double fines for firearm offenses within these areas (excluding designated hunting zones). The law takes effect immediately upon enactment.
