Probably, yes. There is little reason to be on the wrong side of the center line.
In volleyball, it is not permissible to cross the center line during play.
no
It is called a foot fault. You can also have a foot fault if you step over the center line onto the opponent's court.
You can cross when it is safe.
That depends! If the fault line cross cuts the igneous intrusion causing the intrusion to be displaced on either side of the fault and forming a broken mass of rock within the intrusion known as a fault breccia then the fault is younger than the intrusions, as the intrusion must have already existed for the fault to cause it's displacement. If on the other hand the igneous intrusion cross cuts the fault and is un-deformed then it is probable that it is younger than the fault.
This is a rule that recently has been altered. A portion of a player's foot may cross the center line if it does not interfere with play. If the whole foot crosses the line or the portion that crosses the line interferes with play the opposing team is awarded a point.

The insurance wreck does not go up because of your accident to get repairs on your vehicle. Your insurance increasing only when you are at fault. If you weren't at fault then you pay the deductible and your insurance company would fight for you to get it repaired.

Never cross the line
Draw a straight line from opposite corners. Where the lines cross is the centre.
That sounds like you are looking for the word "fault" or "fault line".
