It depends on what you mean. If you are being questioned by a police officer for some reason, the officer can ask for ID. However, at least in most states, an officer cannot take your ID and keep it under most circumstances.
Not using a turn signal is considered an unsafe lane change or an unsafe turn which both are against the law.
yes
No, you would get arrested for driving on an invalid license and your car would just get towed.
I suppose you "can", but the police officer is most likely going to turn you down. He may also see it as an attempt to avoid a ticket, which, at least for me, is not a good first impression.
Usually at the end of their shift, or daily. It is governed by department rules and guidelines.

If they wish to 'own up' to an offense that they committed. they could simply go to the local police agency and ask to speak to an officer or detective (or a Youth Service Officer, if the department has one) and simply tell them about it.
Of course! and they do when it is necessary! A police officer is subject to the same laws as anyone else, and a few extra laws in many states, and at the federal level, because of their role as a police officer. Since officers are the same as anyone else, the same requirements for arresting a police officer exist as arresting anyone else. For any arrest probable cause and an arrest authority has to exist. This is a simplified answer, but essentially, the answer is the same process, and protections that apply to the public apply to the police officer.
It was Benedict Arnold the Colonial officer.
Turn them over to the police.
I just got pulled over because my turn signals were white. The police officer told me that they have to be an Amber color. He did not give me a ticket or anything, but advised that I go to a Pep Boys or somewhere and buy new lights. So I am going to assume that it is PA law for your turn signals to be Amber.
The police may have turned on their lights to get your attention or signal you to pull over, but they did not actually pull you over for a specific reason. It could be a warning or a precautionary measure.
