Interesting question. Back in the day (not sure about now)
Arizona and California used to have “Fruit” road check shacks.
Couldn’t bring in fruit from each others’ state.

I remember that when my grandmother and I would go from Utah to California, they would check and make sure we didn’t have any plants or fruit...I wonder if they still have them???
When I was driving Semis I only drove on interstates...
California still has those checkpoints at their major southern interstate border crossings. I truly feel I am leaving my country every time I go over there. (apologies to CA Freepers the backbone of our fellowship)

Boy I can’t remember the last time we were stopped and asked that question. Even with an RV, I think we just said no and they let us go.
According to the following website there are 17 or 18 such check points? We’ve driven to AZ through Yuma and back several times in the past few years and can’t remember being stopped. Seems even the Border Patrols have been closed. (there is a number to call to report a pest.. wonder if I can report some white haired thief in the White House as a pest?)
