Which until this year was not defined in the law. Common Sense would say you are traveling when you are going somewhere, but over the years the courts, not the legislature, steadily raised the bar on what that meant. It got so the rule of thumb was that you had to cross at least two county lines and stay overnight.
The legislature this year finally defined the term. Basically if you are going somewhere, not committing a crime, specifically not including minor traffic violations, you are traveling and may lawfully have a gun in your vehicle.
Unlike the courts, the legislature can be responsive to the will of the people, even if it took them about 5 decades too long.
