This will likely be the hardest part. Most of the times I've been to Moab I've traveled with a group of friends, all of us have Manx-style street legal Dune Buggies. Every year until I started going someplace else we'd have to argue about the legal-status of our vehicles in order to enter any of the National Parks. One guy in the group liked to argue and carried a file folder with DMV Documents detailing definitions and the like. Telling the Rangers that we drove there on I-70 generally eliminated the argument since SXS's aren't highway legal. Oddly enough the guys in Baja Bugs never had any issue or questions getting into the same National Parks.It doesn't. If you can ride/drive it on the interstate with a driver's license, then it DOES NOT APPLY. Drive and ride as usual if you wish.
