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 improperly1.

Reduced unintentional injuries
Reduced unintentional deaths
Evidence of Effectiveness
There is some evidence that child access prevention (CAP) laws decrease firearm suicide2 and reduce unintentional firearm deaths and injuries among youth3, 4, 5. Additional evidence is needed to confirm effects.
Overall, CAP laws appear to reduce firearm suicide rates among youth under the age of 206, 7. Several studies suggest that state CAP laws reduce unintentional firearm deaths3, 4 and injuries among youth8, especially laws with strict penalties5. 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 laws9.
Some studies indicate that CAP laws have no impact, positive or negative, on unintentional deaths and injuries6, 10, 11. Variability in outcomes may be due to inconsistency of implementation and enforcement in state laws4; studies suggest greater effects with stronger laws (e.g., felony prosecution for violation)4, 5, 8.
Impact on Disparities
As of September 2016, 18 states mandate safe storage of firearms with child access prevention laws12. The definition of minor varies by state, ranging from under the age of 14 to under the age of 181.
Most states prevent local governments from enacting gun laws via state preemption legislation13; 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.
