These are resources that members facing titling/registration issues may find useful. The statues below should be considered models when seeking legislative action in your state. Also linked below are military standards and EPA rulings that may be useful as well. Thanks to Paul Underwood and Kevin Lockwood for these materials.
Model Legislation from Kansas (which has non-restrictive antique auto registration)
In the United States, Motor Vehicles which are manufactured, sold or imported into the U.S. are required to meet Federal Motor Vehicle Safety Standards (FMVSS).
This requirement is found in the U.S. Code, under Title 49 Transportation Subtitle VI Part A Chapter 301 Section 30112
ALL vehicles older than 25 years are exempted from FMVSS requirements.
Note that Code does not specify domestic or foreign vehicles, so ALL vehicles are included in this exemption. Vehicles older than 25 years may still meet FMVSS, they just are no longer required to do so.
This exemption is also found in the U.S. Code, under Title 49 Transportation Subtitle VI Part A Chapter 301 Section 30112 under (b) Non-application (9) vehicle is at least 25 years old.
FMVSS does not apply to vehicles manufactured for the U.S. Armed Forces. BUT, this does not preclude these vehicles from meeting FMVSS. In fact, vehicles manufactured for the U.S. Armed Forces must meet MIL-STD (military standard) equipment requirements which are equivalent to FMVSS equipment requirements.
Because these vehicles must meet MIL-STD requirements, they are exempted from FMVSS requirements.
This exemption is found in the Code of Federal Regulations 49CFR Transportation Subtitle VI Part A Chapter 571.7
MIL-STD-1180B details the contractual specifications which manufacturers must meet for vehicles built for the U.S. Armed Forces.
Vehicles are described as: military wheeled (non-tracked) ground vehicles capable of operating on public highways at normal highway speeds, in most cases without escort, up to and including 5-ton variants.
Table II covers Safety Requirements for military wheeled ground vehicles, and lists equivalent FMVSS #s for each MIL-STD #s.

Wis. Dept. of Admin., Div. of Hearings & Appeals Case # TR-11-0016 acknowledged the equivalent requirements between FMVSS and MIL-STD. http://184.108.40.206/Documents/DHA/Decisions/DOT/2012/110016.pdf
