If I travel through a different state am I subject to that states lift laws, or would it still be under my state (WY) laws? I would assume I am still under my states lift laws.
I am pretty sure that you are subject to YOUR state laws. I registered my truck in Illinois (even though I live in Missouri) just in case......Most MO officers aren't too familiar with Illinois laws
I know in California you must follow the laws here.
I had a Chevy that I had bought in Reno NV & I had not changed the title into my name yet so it still had NV plates. It had 35's, tinted side windows & no mudflaps. CHP pulled me over & asked how long I was goning to visit California? I said I live here & had had just bought the truck. He said that I had to get mudflaps & remove the window tint.
I also got pulled over in Wyoming for no front plate. I had California plates.
My guess is you have to follow the laws of the state your visiting.
