Better yet, have an International Driver's license. :joke:
I heard the deputy here, had never seen one. The Sheriff said, let them go, with a warning.
seriously ..I purchased my bike in Calgary, Alberta, Canada. I needed all my paperwork.
After all that, I carried all the papers, including the important "import" paper.
My bike is "off-road" and registration, license and insurance for a dirt bike is not a requirement, in Montana.
I am planning to take the bike, in the van, to Utah, Arizona, and New Mexico, this Winter.
I have found out: in Utah, I have to meet all the laws of Utah, including license, registration, OHV sticker, and insurance after only 14 days! In Arizona, I have to purchase a $20 Arizona State Lands Resources Permit in case I ride on public land owned by the State of Arizona, and, I can only ride the bike on Forest Service roads having a vertical roadsign, not a horizontal roadsign. However, I can ride on hundreds of miles of legal trails, for ATV, or motorcycle. In New Mexico, I must not leave my van at the trailhead overnight, lest there be severe vandalism. I haven't found out any laws for New Mexico, so far.
I have been posting at multiple ATV, motorcycle, and hiking forums to find out this much.
Ask DMV. Ask U.S. Forest Service district office for a map with the roadsigns printed on the map. Ask BLM for a map showing "jurisdictions" of land ownership.
I'm telling you, it's complicated.
If you just want to ride on roads, I'd say, ask DMV, and find a map showing "scenic highways".
