Relating to the definition of a child for purposes of the offense of making a firearm accessible to a child.

HB 3436 amends Texas Penal Code Section 46.13(a)(1) to define "child" as a person younger than 17 years old for the offense of making a firearm accessible to a child. This changes the age threshold from under 18 to under 17, meaning the law would apply to children aged 16 and younger. The bill directly affects parents, guardians, or anyone responsible for firearm safety who might allow access to children under 17. It takes effect September 1, 2025, and only applies to offenses committed on or after that date.
