Crossing into Oregon, Nevada and Arizona as an informed carrier — whose permits count where, what changes at each line, what to do if you're stopped, the Mexico border, and the best roads for the trip.
Sample cut from the edition whose sources were last read 2026-09-29
You live in California, and you're headed for the Nevada side of Lake Tahoe, spring training in Arizona, or up the coast into Oregon. You carry on a California license. Then you cross the border, and the question comes up: does my license come with me?
The trouble is that only one neighbor honors it. Arizona does, from 21. Oregon and Nevada don't. And on the way home, California's 10-round magazine limit and its rule on ammunition bought out of state meet you at the line.
That is a fixable problem. Once you know what changes at each line, you can plan the trip instead of guessing. You'll know whose licenses count where, what each state expects if an officer stops you, and which places are off limits.
This guide covers Oregon, Nevada and Arizona one at a time. It also covers visitors coming into California, the federal rules for driving on through, Mexico, what to do if you're stopped, the common travel routes, and where to check each rule. Each chapter opens with a short version and ends with real-world examples.
Below: the short version of every chapter, one chapter in full, and two of them from the book's 21 real-world examples.
Your California license works in one neighbor. Arizona honors it from 21, and lets anyone 21 or older carry with no permit at all. Oregon honors no other state's license, and Nevada's 2026 recognition list, in force since July 1, 2026, leaves California off. Coming the other way, California honors no other state's license; a visitor carries here only on a California non-resident license. Near schools across the line, don't count on your California license under federal law. Coming home, magazines over 10 rounds and out-of-state ammunition are the traps. And no gun, round or empty magazine goes to Mexico.
Stories at the end of this chapter: "The Tahoe weekend" and "Spring training in Scottsdale".
This is a summary of four states' laws, federal law and the Mexico border rules, as we read them on September 29, 2026. It's information, education and entertainment, not legal advice, and you're responsible for getting your own legal counsel. Laws change, and courts read them in ways no book can predict. Talk to an attorney licensed in the state you're visiting about your own situation.
Only one thing you carry in California is built to travel: the license card, and only Arizona honors it. Everything else is California law, and it stops at the line. That includes California's transport rule and its license conditions on drinking. Arizona is silent on the listed-handgun condition, so carry only a listed gun there under the license. Coming home, two California laws meet you at the line: the 10-round magazine limit and the out-of-state ammunition rule. By car, you're under the new state's law the moment you cross. By bus, Greyhound bans guns. By air or rail, the gun goes in checked baggage, unloaded and locked, and the law where you land applies.
Six questions, six answers. Going out: Oregon honors no California license, resident or non-resident. Nevada doesn't either. Arizona does, from 21, and needs no permit at all from 21. Coming in: California honors no Oregon, Nevada or Arizona license, and lets nobody carry without a California license. A visitor transports the handgun unloaded and locked, only for a purpose the law lists, such as a trip to a licensed range, or applies for a California non-resident license, available since January 1, 2026. Each neighbor also issues its own license to some Californians, but none of those count back home.
Oregon honors no other state's license, yours included. Hiding a handgun on you without an Oregon license is a crime, and in a car the handgun belongs in the trunk. Open carry in a belt holster is legal under state law from 18, but cities and counties may ban loaded guns in public places, and Portland does. Schools, colleges, hospitals, city halls and the Capitol, each with its grounds, plus state and local agency offices and the terminals of airports with over a million boardings a year, are "public buildings," where a gun is a felony for you, except unloaded and locked in your car at a school, or cased for checked baggage at an airport; no other has a car exception. Court facilities have their own felony rule. Oregon's magazine limit from Measure 114 can't apply before January 1, 2028. And you don't have to tell an officer you're armed.
Nevada doesn't recognize a California license. Carrying a hidden gun there without a permit Nevada recognizes is a felony. Nevada issues its own permit to non-residents; California and Oregon won't honor it, and Arizona does. No Nevada statute we read bans open carry, and cities and counties can't regulate carrying. The rules that bind everyone: no gun on school, child-care or university property, even in your car, and no gun in your possession at 0.08 or while impaired. Loaded rifles and shotguns ride with no round in the chamber. Casinos have no gun statute of their own; the house rules bind through trespass.
It honors your California license from 21, and lets anyone 21 or older who isn't barred carry, open or concealed, on foot or in the car, with no permit at all. The traps are specific. Where drinks are served, only a permit holder may carry, only a concealed handgun, only where no "no firearms" sign is posted, and never while drinking; whether your California license counts isn't settled, so with only that license, treat those places and their lots as closed. On school grounds, the gun in the car must be unloaded, out of sight and the car locked if you step away, and in a locked case for the federal school zone. A government building may ask you to check your gun in its lockers. If an officer stops or detains you and asks whether you're carrying concealed, you must answer truthfully. And tribal land along the Colorado River runs on its own codes.
Federal law follows you across every line. The rule that needs the most planning is the federal school zone, because across the line you can't count on your California license near a school. Then come places: federal buildings, post offices and their lots, dams run by the Bureau of Reclamation, Hoover Dam above all, and military bases. National parks, wildlife refuges, national forests and Bureau of Land Management land mostly follow the state's law. Safe passage covers a trip through a state only between places where you may lawfully have and carry the gun, with it unloaded and out of reach. Federal law on drug users is separate from every state's cannabis law. And Mexico is closed to guns and ammunition.
No state in the region makes you announce your gun the moment a stop starts. Arizona comes closest: if an officer asks whether you're carrying concealed, you must answer truthfully. California makes a license holder show the license and hand over the gun for inspection when an officer demands it. Nevada makes a permit holder show the permit and ID when asked. Oregon has no statewide duty to tell, though an officer may check whether a gun in a public building is loaded, and Portland lets officers inspect a gun in a public place. We found no advice for armed drivers from any of the four states, so the calm habits in this chapter are our suggestions, not law.
Nine ways across: two into Oregon, four into Nevada and three into Arizona. On the way, California state parks, casinos and tribal land need the most care.
Each state speaks for itself. In California, the Department of Justice's Bureau of Firearms answers general questions, and a county sheriff or city police chief issues the license. In Oregon, the county sheriff licenses and the State Police run gun checks. In Nevada, county sheriffs issue permits and the State Police keep the recognition list. In Arizona, the Department of Public Safety runs the permit program. Everything here was checked September 29, 2026.
From the examples at the end of Driving on through — the federal rules for crossing state lines
Victor, 31, lives in Chula Vista and holds a California license. He's driving to Tijuana to meet friends for lunch, crossing at San Ysidro.
Mexico treats even an empty magazine or a spent casing as contraband. The night before, he takes the pistol, both magazines, his ammunition and a stray casing from under the seat out of the car. They go into his gun safe at home in Chula Vista, and he drives across with nothing to declare.
From the examples at the end of Common travel routes
Ivy, 49, lives in Santa Rosa and holds a California license. She drives the 101 north for a weekend of redwoods, then a night in Brookings.
She hasn't mapped every state park the 101 passes on the way north, so before she leaves home she unloads the pistol and locks it in her roster-listed lock box, which rides in the trunk, out of plain view. Prairie Creek is California state park land, where the park rule bars carrying a gun for everyone, license or not, and the sensitive-places list closes it to license holders. So the pistol stays locked away while she watches the elk. She leaves it that way into Oregon, which won't honor her license, and through Harris Beach and back. Coming home, the Smith River inspector checks for fruit and plants and waves her on.
