Guns must be transported in a locked container, like a gun safe, or equipped with a tamper resistant safety device, so the gun is inoperable. The penalty is up to $10,000 in fines and 10 years imprisonment. Guns must be unloaded when stored in a gun safe. Gun owners need to consult with state authorities before crossing boarders, even if their firearms are in a gun safe. Not all gun cases are legal to use as gun safes.
