I got a speeding ticket (yes again) in Cobb Co this time.

I was coming down hill on a four lane road, the officer was at the bottom and clocked me by laser doing 15 or 16mph faster than the posted speed limit. (51mph in a 35zone)

I have heard many time there is a statue that states if you are coming down a hill with more than 4-7% incline, then they will throw it out.

A.) Is this true, have anyone else heard this ?

B.) What is that Statue?

My ticket was speeding 40-6-181

Thanks for your help!
