how far can a qb advance before he cant pass?

Question

???

Answer 1

The line of scrimmage. Or the invisible line running from sideline to sideline horizontally from where the ball is snapped.

Answer 2

Ahh but here is a point about the line of scrimmage and what we define as a pass. If a QB is forced to advance by running and is about to be hit, could not he lateral the ball to another player who then advances? Makes you think about what defines a pass. because i may be wrong but a Lateral is throw the ball to another just as is a pass.

Answer 3

The Quarterback cannot pass beyond the line of scrimmage. This will result in a penalty.

Answer 4

the line of scrimmage.the line of scrimmage is the yard line where the ball was snapped from on that play.if he crosses that yard line and passes,then it is a penalty called a illegal pass....15 yard penalty i believe.also,the offensive linemen blocking for the QB can not cross that line if it is a pass play.if they do,they will get penalized...15 yards...illegal man down field.once the ball is passed..then they can cross the line of scrimmage to help block down field.

Answer 5

once he crosses the line of scrimmage, the option of passing is gone. if he passes after crossing the line, it is a penalty of 5 yards and replay the down.
