THIS IS NOT A STUPID QUESTION, BECAUSE MOST ALL WILL GET IT WRONG.
SIGNALS, SIGNS AND ROAD STRIPING HAVE BECOME STANDARD FOR THE USA. WITH THAT SAID IN FLORIDA THE LIGHT YOU GET AT(ROUND OR ARROW) THE INTERSECTION DEPENDS ON THE DIRECTION OF TRAVEL THROUGH THE LIGHT. EXAMPLE: AT A STOP LIGHT YOU HAVE 3 LANES LEFT TURN, STRAIGHT ACROSS & RIGHT TURN YOU WILL HAVE 3 LIGHTS LEFT ARROW, ROUND AND RIGHT ARROW, THAT TELLS YOU THE LANE YOUR IN THE MOVEMENT YOU CAN MAKE. AN ARROW MEANS YOU HAVE TO GO IN THAT DIRECTION, SO LEFT ARROW MEANS ONLY LEFT TURNS, SAME WITH RIGHT ARROW. IF YOU ONLY HAVE A ROUND LIGHT YOU WILL BE ON A SINGLE LANE ROAD THAT MEANS YOU CAN TURN LEFT, RIGHT OR GO STRIGHT. HOPE THIS HELPS YOU UNDERSTAND.
HERE IS THE ANSWER TO YOU QUESTION. REMEMBER FLA TRAFFIC LAWS. YOU CAN TURN RIGHT ON RED( UNLESS SIGNED WITH EITHER TEXT OR SYMBOL SIGN FOR NO TURN ON RED) BUT YOU MUST STOP AND YIELD TO ONCOMMING TRAFFIC THEN YOU CAN GO. SO IF YOU HAVE DUEL RIGHT TURN LANES WITH RED ARROWS AND NO SIGN BOTH LANES CAN TURN RIGHT ON RED IF THE LANES ARE CLEAR AFTER YOU COME TO A COMPLETE STOP.
