Going west on 19 mile road to Hayes there is a left turn lane, a straight through lane and a right turn lane only. There is no warning sign as to the "right turn only" lane. Only when you get to the light can you see the sign that it is a right turn only on the corner. There needs to be a "right turn only" sign way before you get to the corner. It is an issue when you are in the right lane waiting to turn right with the green arrow and then you get some car in the front that is going straight then backs traffic up so that car can merge into the straight lane while other cars are held up in the right turn lane.
