Your first appearance for your Georgia speeding ticket is just an arraignment and the officer may or may not be there. The judge will allow you to enter a plea and pay your fine so take cash since they will not accept a check. Most courts will offer to reduce your speed by 3 to 5 mph in return for a guilty plea.This is important since a 14mph or under speeeding ticket will not be posted to your record and not increase your insurance premiums. Traffic school or a deferment are not options to keep the ticket off your record in Georgia.ome states do not enter minor out of state speeding tickets so check with your DMV to be certain what effect the Georgia ticket will have on your license before you just send in your money. For example a 15mph+ ticket in Georgia will earn a North Carolina driver a 30 day suspension of their drivers license.
