Headlight Flashing is Free Speech

I never do this because how would oncoming motorists know exactly what the heck I'd be trying to tell them? Is it like Morse Code? Three blinks cops? Two blinks elk in the road? Anyway Associated Press tells us that a judge in southern Oregon has ruled that flashing headlights to warn other drivers about police is protected under the state constitution. The judge ruled that a driver who was cited for misuse of headlights is not guilty because headlight flashing in this case was a form of free speech. If I went through an area being patrolled I wouldn't warn oncoming motorists anyway, would you? A hazard in the road, sure. But if you're driving naughty then maybe you deserve to be pulled over. So I won't be flashing you! Wait...what? DB
