No, wait until you know it's safe to proceed.
Depends. If the light has a sign next to it that says 'Yield on green light' it means you can go when the light is green and there is no traffic coming from the opposite direction that could hit you. If there is no sign wait for the arrow.
If both have a green light the person making the right hand turn has the right of way. There person coming the opposite direction is crossing traffic and should yield to any on coming vehicles whether they are turning right or going straight through.
You continue through the turn but only after you make sure that there is no oncoming traffic. It is your responsibility to yield to vehicles that are coming straight through the intersection.
When turning left at an intersection with a green arrow, you have the right of way over oncoming traffic and pedestrians.
A green light on a traffic light set (in the UK) means automobile traffic is free to go. Walking out when commuter traffic lights are on green is a bad idea. Answer from @MunicipalSigns: In general: A steady GREEN traffic light means you can go through the intersection. You must yield to emergency vehicles and others as required by law. If you are stopped and then the light turns green, you must allow crossing traffic to clear the intersection before you go ahead. A GREEN arrow means you can safely turn in the direction of the arrow. There should be no on-coming or crossing traffic while the arrow is green. If you are turning left, a steady green traffic green light means you may turn but only when safe to do so. Oncoming traffic has the right-of-way. Be alert for signs that prohibit left turns. When turning right or left, watch for pedestrians crossing in front of your vehicle.
when a green arrow points to the left :]When you are turning left as directed by a traffic signal left turn arrow.
..... wait for the light to turn green to proceed -or- if turning right - come to a full stop and after checking for oncoming traffic on the cross-street and pedestrians, turn right with caution.
Green Because on traffic lights there's red and green as the opposite.
Normally, the green arrow would indicate that the opposing traffic has a red light and as such the green arrow traffic has right of way.However, due to mechanical or planning errors it is possible that the opposing traffic will also have a green light. If this happens, the opposing traffic (by virtue of going straight) has right of way. If this opposing traffic does not appear to be stopping, green arrow traffic should assume that opposing traffic has a green arrow and right of way. In the event of a collision when both have green, green arrow traffic (turning left) will be found at fault except in no-fault states where this will be considered a no-fault accident.
Check the DMV manual.
Yes.unless you have a protected left turn such as with a green arrow.
Normal signal: Turn left if the signal is green and there is no on coming traffic from the other side. Separate left turn signal: Turn left if the arrow is green. Do not wait for the on coming traffic. It is intended to move traffic through from the left lane. If the arrow is red or yellow, but the main signal is green, you may still turn left, but must yield to on coming traffic from the other side. Left on green arrow only: You must not turn left until the small arrow is green. Many drivers from out of state are confused by this, but if obeyed well, the traffic has the highest flow possibility using these principles. Out of state drivers tend to stay parked at the Separate left turn signal, if it is red or yellow, even when there is no on coming traffic and the main signal is green. It is a better safe than sorry approach, but it slows down traffic in the big picture.
