My understanding that the speed limit sign is supposed to be posted 200 feet before the actual speed limit zone changes (an imaginary line in a real spot), thus giving time for vehicles to slow down and account for people who maybe cannot see the sign from 200 feet away.
This could be different in each municipality.
Speed trap for sure.

Never show a cop that you have any amount of cash, this, in their minds, means you are a criminal about to commit crimes using cash. Asset Forfeiture is one of the biggest evils perpetrated by our "protectors" This practice must be outlawed!!!!
Never do anything in traffic that you can be pulled over and this will help keep you safe from the evils some courts and towns practice.
