Hold a piece of white paper behind a half open side window. The windows are not clear. I got a sample of 50% and 35%, and compared the 50% on the glass to the 35% by itself. The combination of the 50% plus the window appeared close to the 35% alone, so based on that I used 50%, as my state limit is 35%.
70% does seem awfully high as the limit. Even considering the low light levels in Canadian winters 50% wouldn't seem a problem. Someone in Ottawa hasn't got a clue.
