Extreme risk protection order (ERPO) laws, sometimes known as gun violence restraining order or "red-flag" laws, are risk-based, temporary, and preemptive protective orders that authorize the removal of firearms from individuals determined to be at risk for committing gun violence against others or themselves. With ERPO laws in place, law enforcement, family members, or medical professionals can petition a court to temporarily restrict a person's access to firearms if they believe that person is at risk of hurting him or herself or others.
