OMGosh, The Dreaded Red Arrow

I grew up in Florida. In Florida there really wasn't a problem with turning right in red arrows directing right turns, so long as one was in the rightmost lane.

I move to Georgia, and I was a bit cautious at first, never turning, even if people would blow their horns at me or flash their headlights.

Then I'd started to buckle, starting to turn. I'd learnt tonight I've been contravening the law.

In Florida:

What does the red arrow mean?
A red RIGHT arrow means that you must come to a complete stop at the marked stop line or before moving into the crosswalk or intersection. After stopping, you may turn RIGHT on the red arrow at most intersections if the way is clear. Some intersections display a "NO TURN ON RED" sign, which you must obey.
A red LEFT turn arrow means that you must come to a complete stop at the marked stop line or before moving into the crosswalk or intersection, and shall remain stopped until a signal indication to proceed is shown. After stopping, the motorist facing a red LEFT turn arrow or red circular signal indication is permitted to enter the intersection to turn left from a one-way street onto a one-way street with traffic moving to the left except when a " NO TURN ON RED" sign is displayed.
