In 1999,
Connecticut became the first state to enact a red flag law,
after a rampage shooting at the Connecticut Lottery. It was followed by
Indiana, which adopted its legislation in 2005; called Jake Laird's Law, it was named after an Indianapolis police officer was fatally shot by a mentally disturbed man. Subsequent red-flag laws were adopted by
California (2014),
Washington (2016), and
Oregon (2017). After the
Stoneman Douglas High School shooting in
Parkland, Florida, in 2018, that number more than doubled, as more states enacted such laws:
Florida,
Vermont,
Maryland,
Rhode Island,
New Jersey,
Delaware,
Massachusetts,
Illinois, and the
District of Columbia. A
content analysis study published in 2022 examined newspaper articles published in 2018 in three states that passed ERPOs after the 2018
Stoneman Douglas High School shooting in
Parkland, Florida (Florida, Rhode Island, and Vermont) and three states that did not (Pennsylvania, Colorado, and Ohio). The study found that the passage of ERPOs was associated with media coverage that used official policy names/acronyms (as opposed to simply "red flag"); accurately portrayed gun violence as a preventable problem, and that referred to ERPO policies in other states. The survey found that "although only one in four articles cited scientific evidence related to gun violence generally, articles about passing states were significantly more likely to cite the small but growing body of research about ERPO implementation and effectiveness. These findings point to the value of relevant data, likely in combination with the lived experience and advocacy efforts of those most impacted, for building policy momentum through the media." In addition to allowing police and family members to petition for entry of an extreme risk protection order, Three other states enacted red-flag laws in 2019:
Colorado,
Nevada and
Hawaii. The Colorado, Nevada, and Hawaii laws all went into effect on January 1, 2020. In 2020,
New Mexico became the 18th state to adopt a red-flag law, after Governor
Michelle Lujan Grisham signed legislation on February 25, 2020. New Mexico's law went into effect on July 1, 2020. In
Virginia, the
state's General Assembly, then controlled by Republicans, voted down red-flag legislation in its January 2019 session. After the
Virginia Beach shooting later that year, Governor
Ralph Northam, a Democrat, called the Republican-controlled General Assembly into
special session to consider gun-control legislation. The legislature did not vote on any gun legislation. After the Democrats won control of both chambers of the General Assembly in the
fall 2019 elections, for the first time in more than two decades, Northam vowed to reintroduce gun control proposals, including a red flag bill. The General Assembly subsequently passed an emergency substantial risk order (ESRO) law, on a party-line vote in the
Senate and a nearly party-line vote in the
House of Delegates. Northam signed the legislation into law in April 2020, alongside four separate gun measures.
Fairfax County, Virginia and the
Alexandria-based gun-violence prevention nonprofit group Safer Country have become leaders in awareness campaigns to inform the public and law enforcement about the use of Virginia's ESRO law. Some local sheriffs in rural Colorado counties refused to use the state's risk-based gun violence prevention, with some declaring their counties "sanctuaries" from gun laws they opposed; many of the sheriffs reversed course after gun violence incidents in their communities. A 2022 analysis of court records by
KHN found that, two and a half years after the passage of Colorado's risk-based gun violence prevention law, petitions for protection orders had been filed in 20 of the 37 counties with sheriffs who previously said that they would refuse to use or enforce such laws, and that such petitions were often filed "by the very sheriffs who had previously denounced the law." (although Elder said that it would enforce orders granted by the courts on the petition of non-law enforcement). In May 2023,
Minnesota and
Michigan became the 20th and 21st states to enact red flag laws. Minnesota's law went into effect on July 1, 2023. Michigan's law went into effect in February 2024. On November 4, 2025, Maine
voted to pass a Red Flag Law.
Proposed or pending state legislation Other
state legislatures considered similar legislation. In the recent past, red-flag bills were being considered but did not pass in the following states: •
Arizona: A red-flag bill previously died in the
Arizona Legislature, but in 2019,
Governor Doug Ducey renewed pressure on legislative Republicans to pass the law in the wake of the
shootings in El Paso, Texas and
Dayton, Ohio. In 2020, Gov. Ducey reversed his position and stated, “As long as I am governor, there will be no red flag law in the State of Arizona." •
North Carolina: Since 2018, red flag bills introduced by North Carolina Democratic legislators have been defeated or stalled in committee the Republican-controlled
state House. •
Ohio: After the Dayton shooting, Ohio's Republican governor,
Mike DeWine, announced that he wanted Ohio's Republican-controlled legislature to pass a red flag law. Two months later, however, DeWine retreated from this proposal. •
Tennessee: A red-flag bill had been introduced in the
Tennessee Legislature, but in 2019 the Republican-controlled legislature declined to take up the bill, and Governor
Bill Lee did not commit to support it. In 2020, Democratic State Senator Sara Kyle proposed Senate Bill 1807. Following the
Covenant School shooting on March 27, 2023, after sustained public protest from parents, students, residents and legislators, Governor Lee asked the TN state legislature to work on a red flag law on April 11, 2023. •
New Hampshire: The Democratic-majority
New Hampshire Legislature passed a red-flag bill, but it was vetoed by Republican Governor
Chris Sununu. •
Nebraska: In 2019, Legislative Bill 58 was introduced which includes red-flag provisions. •
Kentucky: In 2022, House Resolution 74 was introduced which includes language opposing the adoption of a red-flag law, following previous attempts in 2019. •
Pennsylvania: Similar legislation was proposed, but did not pass.
Federal grant program On June 25, 2022, President Joe Biden signed the
Bipartisan Safer Communities Act that included several changes to U.S. gun laws, one of which authorizes governments of individual states to receive grants from the federal government if they enact and enforce red flag laws. ==Provisions==
