Re: Speeding in Kentucky
First, let me explain that I am NOT an expert on KY laws, but I don't think anyone else here is either. So, if I'm wrong, I apologize in advance.
As far as I know, there are NO laws governing how far apart speed limit signs can be. The only "standard" is that a "speed zone" MUST have a sign at the beginning of the zone (which is why speed limits take affect AT the sign). It is "suggested" that signs be posted at all entrances to freeways and after "major" intersections on other roads.
That said, in most states (however, after a quick search, I cannot find such a law for KY), it is an affirmative defense if you can show that there were NO speed limit signs from where you entered the highway to where you were pulled over.
MANY moving radars can do that. This one, for example, even notifies the officer of the direction of the target vehicle.
Several states (my state, WA, for example) have passed laws that remove the requirement to have a defendant sign the notice of infraction. I don't know if KY has done the same. Call the Clerk of the Court to see if a defendant's signature is a requirement.
Unless you want to post more details, including the statute you were cited under (probably 189.390), there's not much we can do. Sorry.
Where am I going? And why am I in this handbasket?
