Before moving out of Utah Beware of other States Gun Laws! Read the fine print.
If you are moving out of the State of Utah and have Firearms check that State firearm law. Some states will arrest you and charge you for having a firearm in your vehicle.
According to the ATF
May a person who is relocating out-of-State move firearms with other household goods?
Yes. A person who lawfully possesses a firearm may transport or ship the firearm interstate when changing his or her State of residence. If using a moving company, the person must notify the mover that firearms are being transported.
Certain NFA firearms must have prior approval from ATF before such firearms may be moved interstate. He or she should also check State and local laws where relocating to ensure that movement of firearms into the new State does not violate any State law or local ordinance.
