The light at Hoosick st (Rt 7) and 15th st for west bound traffic needs a left hand turn arrow. There are 6 lights on Hoosick St., 5 have left turn arrows, except the one at 15th St.. The lack of an arrow here causes major back ups , road rage and probably a few accidents. I have never heard a logical explanationas to why this intersection did not get the left turn arrow.
