No, to every force there is an equal and opposing force
Speeding alone does not cause injuries, unless the 'G' forces are excessive. It's stopping suddenly (in a crash) that causes injuries.
Forces always occur in pairs. They even have reaction force pairs occur when there is no motion
No,it is balanced forces
True.
According to Newton's three laws of motion:Whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction.This indicates that Forces occur in pairs. However these pairs do not act on the same object simultaneously, but on two separate objects.
The two forces must be equal and opposite.
first law
If you agree that Sir Isaac Newton generally knew what he was talking about, you can take the simple answer from his work. Newton's so-called 3rd law of motion says that for every action, there is an equal and opposite reaction. That pretty much rules out the possibility of a single isolated force.

You have flung a wide net there.
