A: Yes, and you may demand/sue for reimbursement from your daughter-in-law. I'm guessing she doesn't have the money, but you could draw up an agreement, signed by her, that she pay you in installments and/or pay, or start paying, at a specified future date. If the accident was her fault, shouldn't she take responsibility?
A: That's easy - just look at the traffic signals statute, Fla. Statutes Sec. 316.075, at http://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&URL=0300-0399/0316/Sections/0316.075.html Regarding green arrows, it states: Vehicular traffic facing a green arrow signal, shown alone or in combination with another indication, as directed by the manual, may cautiously enter the intersection only to make the movement indicated by such arrow, or such other movement as is permitted by other indications shown at the same time, except the driver of any vehicle may U-turn, so as to proceed in the opposite direction unless such movement is prohibited by posted traffic control signs. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
A: Generally, yes on both. You are apparently representing yourself. If you are in civil court, you must read and understand the Florida Rules of Civil Procedure, and if you are in family court, you must read and understand the Florida Family Law Rules of Procedure. Both are on-line. If you make a motion related to discovery, it's best to cite the applicable rules.
