Kokua Line: What are rules on windshield tint, license plate covers?

Question: I nearly got hit by a car on Kapiolani Boulevard by the mall. I was in the crosswalk, with the signal to walk. I tried to make eye contact with the driver, but their windshield was so dark I could barely see them and obviously they didn’t see me! And I couldn’t read the license plate. Does anybody check this stuff?
