We in Missouri have some interesting "old" laws like the peaceable journey law Here is some things I took from our Highway patrol website.
Carrying A Weapon In A Vehicle
In addition to the concealed carry endorsement discussed above, Missouri now permits any person who is at least 21 years old to transport a concealable firearm in the passenger compartment of a motor vehicle. No concealed carry endorsement is required. Under the old law, the peaceable journey exception to the unlawful-use-of-a-weapon law permitted travelers on a continuous peaceable journey to carry a concealed weapon. The peaceable journey exception is still in the law, and may apply in circumstances where the new law does not (i.e. if the person is less than 21 years old). Also, any coroner, deputy coroner, medical examiner, or assistant medical examiner may carry a concealable firearm upon or about their person without an endorsement.
Note: This law does not affect the law prohibiting possession of a concealable firearm by a dangerous felon.
Additional Information
If you are arrested for DWI and are carrying a concealed weapon, you also may be arrested for possession of a firearm while intoxicated. “Possession” would include having the weapon in the vehicle, not just on your person.
Missouri’s carrying concealed law recognizes all out-of-state permits, including those from political subdivisions — cities and counties. Also, keep in mind that Missouri’s peaceable journey law will apply to travelers, including those who do not have a permit.
Out-of-state residents cannot obtain a Missouri concealed carry endorsement. However, nothing prohibits Missouri residents from obtaining a concealed carry permit from another state, and those permits would be valid in Missouri.
Not all states honor Missouri’s concealed weapons endorsement. It is the responsibility of the endorsement holder to comply with the laws of all states/jurisdictions in which he carries a concealed weapon.
Frequently Asked Questions:
Q: What if I fail to renew my endorsement? Is there a grace period?
A: Yes. There is a grace period of six months; but, there is also a $10 per month late fee assessed by the sheriff. The sheriff is required to keep records and report all instances of non-renewal to DOR at the end of the six-month grace period. DOR will then immediately cancel the endorsement.
Q: What if I misplace my driver’s license?
A: You must notify the sheriff within seven days of losing your driver’s license. The sheriff will issue a duplicate certificate of application. You must then present this duplicate to DOR to obtain a duplicate driver’s license with a concealed weapons endorsement.
Q: Can I obtain a separate ID card, so my driver’s license won’t show the concealed weapons endorsement?
A: Yes, you can. But, be aware that any law enforcement officer who checks your license through DOR will be notified you are authorized to carry a concealed weapon.
Q: What happens if a disqualifying fact is discovered after the endorsement is issued?
A: There are provisions for both the sheriff and the director of revenue to revoke a person’s endorsement. The courts will be responsible for reporting disqualifying judgments to DOR.
Q: Is the list of carrying concealed endorsement holders a public record?
A: No, it is private information. This information can be further restricted in the same manner as other driver information if the holder chooses to restrict it. However, as with other restricted listings, law enforcement will have access to that information.
Q: How does the new law affect the old peaceable journey exception?
A: It does not. You may still carry a concealed weapon on a continuous peaceable journey through the state. This includes Missourians whose trip begins and/or ends in Missouri.
Q: What if I’m stopped by law enforcement? Any suggestions?
A: Where possible, it’s best to stay seated in your vehicle, with both hands on the steering wheel. Do not reach to an area where your firearm is concealed without first advising the officer that you possess a firearm in your vehicle or on your person.
Q: Does a person carrying a weapon in a vehicle also have to have a permit for the gun?
A: No. A weapon may be carried anywhere in a vehicle, even concealed on the person, under the vehicle exception.
Q: Does a concealed carry endorsement allow a holder to carry a concealed pistol on a public bus?
A: No. Only law enforcement, commercial security personnel, and persons with consent of the owner are exempt from this provision. (See Section 578.305, RSMo.)
