Im planning on making a trip on my Harley from Montana, thru Idaho and Utah wearing a drop-leg Serpa holster. It is totally open and visible.
These 3 states are all fully open carry.
However, are there any special requirements for Motorcycles that anyone knows about ?
IN UTAH you are prohibited from having a firearm in a vehicle (Motorcycle is a vehicle) but there are some exemptions...
First you must be 18 years or older then YOU must be in legal possession (you own it or have permission of the owner to have the vehicle) OR as a passenger permission of the person in control of the vehicle. As long as you meet these exemptions the you can carry, wear, conceal, dangle, hang from a string a firearm that is unloaded, loaded, painted pink or orange or whatever BUT....
Don't step out of the vehicle or OFF the motorcycle with a loaded (Utah defines unloaded as no round in firing position and it must take more that one action to cause the weapon to fire) and/or concealed firearm. It is against Utah law to have a loaded firearm on a public road. Permit holders are exempt (Utah recognizes ALL permits issued by any state or county).
Utah recently changed it's GFSZ law to basically on the property or inside the buildings for K-12 AND includes colleges/universities. Federal 1000 foot from the property line GFSZ still applies UNLESS you have a permit ISSUED you by UTAH.
Only prohibited places in Utah besides the standard Federal No carry zones would be inside a private residence where you have been told by the occupant that weapons are not permitted or there is a sign, LDS church meeting houses (infraction only), courthouses, in secure portions of jails/prisons/mental or psychiatric facilities, secure portions of airports ( before TSA sections are good to go). OK to carry in State and federal forests/parks/monuments but NOT inside the buildings of Federal parks, rangers offices, and POST OFFICES (outside property is prohibited also). Generally "No weapons/gun" signs on carry no legal weight except for those specific areas above, but IF you are asked to leave a business, hospital,shopping mall, store and refuse you may be charged with Trespass.
And IANAL, the preceding is not legal advise but rather my opinion ONLY.
