A great ruling by a federal judge...................

The law says to have lights on during rain. Not sure what lights though and it seems to be ignored a lot during drizzle.
Now that I've read some more post I also have thought about all those people that flash their lights to tell others that their headlights are not on.
But I wonder if that is not a grey area. (pun)
Wow, if there was a law against flashing headlights (with or without "intent") think of the can of worms that would open.

What's interesting about this case is the use of hindering prosecution. If you flash your lights to warn of deer, or to let people know their lights are out, you're not hindering prosecution. If you use them to warn drivers who are speeding, which is technically a crime, and do so when you know the police are looking for them, then you are in fact hindering prosecution. Unless you could show you flash your lights to warn drivers to slow down when there is no speed trap around, it's tough to get around the hindering charge. But in the description of the city law in the article, you can't flash your lights for any reason, which would be a violation of free speech rights.

Oh great! Then I guess those who drive with the high beams on permanently or the left turn signal on across three states are protected under free speech also.

How would one accomplish that, one would have to be holding the thing down at all moments to enshire that the signal does not differ
