while your lanes are green, the left hand light blinks yellow, if you think your going to get a green arrow when the light turns yellow. while your wrong cause it's doesn't turn green, very dangerous! if something have been running one way for for years and you change it, well expect more accidents. ever since they put in those lights that run of camaras, i have almost got into 2or 3 accidents at that light! FIX IT!
