Child firearm access prevention laws

Evidence Rating

Some Evidence

Health Factors

Decision Makers

Child access prevention (CAP) laws impose penalties on adults who allow children unsupervised access to firearms or violate firearm storage requirements (e.g., storage with a locking device in place). Federal law does not regulate child access to firearms. Laws vary by state; some states impose criminal liability for adults who give children unsupervised access to firearms or provide a minor with a firearm, while others impose civil or criminal liability when firearms are stored improperly (LCPGV).

Expected Beneficial Outcomes (Rated)

  • Reduced suicide

  • Reduced unintentional injuries

  • Reduced unintentional deaths

Evidence of Effectiveness

There is some evidence that child access prevention (CAP) laws decrease firearm suicide () and reduce unintentional firearm deaths and injuries among youth (, , ). Additional evidence is needed to confirm effects.

Overall, CAP laws appear to reduce firearm suicide rates among youth under the age of 20 (, ). Several studies suggest that state CAP laws reduce unintentional firearm deaths (, ) and injuries among youth (DeSimone 2013), especially laws with strict penalties (). CAP laws may also increase school safety: in states with CAP laws, high school students are less likely to carry guns, be threatened or injured by a weapon, and miss school due to safety concerns than peers in states without CAP laws (Anderson 2016).

Some studies indicate that CAP laws have no impact, positive or negative, on unintentional deaths and injuries (, , ). Variability in outcomes may be due to inconsistency of implementation and enforcement in state laws (); studies suggest greater effects with stronger laws (e.g., felony prosecution for violation) (DeSimone 2013, , ).

Impact on Disparities

No impact on disparities likely

Implementation Examples

As of September 2016, 18 states mandate safe storage of firearms with child access prevention laws (AAP-Firearms). The definition of minor varies by state, ranging from under the age of 14 to under the age of 18 (LCPGV).

Most states prevent local governments from enacting gun laws via state preemption legislation (Grassroots Change); as of 2015, only seven states (California, Connecticut, Hawaii, Illinois, Massachusetts, New Jersey, and New York) allow local governments to enact gun laws, with exceptions for local laws relevant to minors in some states, for example, Maryland and Texas.
