These regs tend to follow ADR's as a general rule, but may vary from state to state.

Interesting to see that on page 2 of 4 it states that most windscreen manufacturers state that 98% of harmful UV rays are dealt with. The film tint version deals with guys that suffer medical conditions ... perhaps an Albino or those suffering dermatitis or similar.
There's many types of UV however and I wouldn't put any faith in claims by windscreen manufacturers as they are talking about UV in general and a lot of your sun exposure also comes from the side windows (especially the arms).

Ordinary glass will block some UV-A and nearly all UV-B.

UV-A (long wave): Most likely to causes cancer and aging of the skin.
UV-B (medium wave): Most sunburn and some cancer.
UV-C (short wave): The ozone layer takes care of this.
