Left turn
Yes it is
You can pull halfway into an intersection after making a full stop to make a left turn. However, your light must be green and you must be waiting to turn.
Yes, the LEFT TURNER must ensure that the turn can be made in safety. If not, do not make the turn - go to the next intersection and then come back.
Yes, a right turn signal means that a right turn is coming up at the next intersection and you can turn right. The left turn signal sign means the same thing, but that you can turn left.
You complete the turn when it is safe to do so.
no
What ever car was turning is at fault unless they had a green arrow. you have the right away when it comes to 4 way stops with the turn lights.. if the turn light isn't on then they have to wait for you.
Oncoming Traffic
...aimed straight forward; not turned.
Left turns are either permissive (no arrow), exclusive/permissive (allowing turns on gaps in traffic after the arrow expires, usually with a five-section display) or exclusive- only (no turns after the arrow expires, three-section display).Additional: At those intersection controlled by green turn arrows - there is no uniformity among the states as to whether the left turn arrow leads the regular light sequence or follows it. That decision is usually left to the Highway Dept. traffic engineers.More: The choice of leading left turn or lagging (following) left turn is not usually a policy of the highway department, but is an engineering decision made separately for each intersection. Often, to achieve signal progression (lights turn green as you come to them), the choice of leading or lagging left turn is forced by the progression plan. Often, to make the progression work better on a two-way street at a particular intersection, one direction on the street has a leading left turn, but the opposite direction has a lagging left turn. This way, the cars from each direction can arrive at this intersection at different times.The lagging left turn has a disadvantage. If left turns are permitted on a circular green, a lagging left turn in one direction causes a hazard: One direction on the street receives circular yellow, but the opposite direction remains green. A driver receiving the yellow might turn left across live traffic moving on a green, thinking they will stop. To prevent this, either the signal with a lagging left turn must prohibit left turns on circular green, or use the new flashing yellow arrows.A flashing yellow arrow display uses a flashing yellow arrow instead of a circular green, and has a 4-section display with all arrows.

You didn't say WHERE you were waiting, so I have to provide you with TWO answers: 1) If you were waiting behind the limit line, the light turned red, and 7 seconds later you made a left turn, you've made an illegal turn. 2) If you were waiting beyond the limit line, with so much as your bumper hanging over the limit line, but ideally, with your vehicle at least 1/4 of the way into the intersection or more, YOU HAVE THE RIGHT OF WAY against traffic that is running perpendicular to you no matter how long it takes the oncoming traffic to clear the intersection so that you can complete your left turn and clear the intersection. It doesn't matter how long your light has been red, you OWN that space until you can complete the turn. That is the law in most states, to the best of my knowledge. -- Do not confuse this "LEFT TURN YIELD ON GREEN" situation with blocking the intersection when your intent is to go straight ahead. If the traffic in front of you is so congested that you can not clear the intersection quickly, then you should never have entered the intersection in the first place. -- Do not confuse this "LEFT TURN YIELD ON GREEN" situation with a sign that reads "LEFT TURN ON GREEN ARROW ONLY". The majority of drivers in my state do not understand the difference between these two signs.
