Rule 5 – Fouls
A foul occurs when a part of the player’s body encroaches on or goes beyond the foul line and touches
any part of the lane, equipment or building during or after a delivery. A ball is in play after a delivery
until the same or another player is on the approach in position to make a succeeding delivery.
The certification and inspection committee of a local association can require that the foul line be
plainly marked on the walls, posts, division boards or any other structure in a bowling center on a line
with the regular foul line.
When a foul is recorded the delivery counts, but the player is not credited with any pins knocked down
by that delivery. (See Rule 6b.)
The foul line is of infinite length including walls, floors, posts and ball returns. A foul is not
committed when foreign objects such as pens, jewelry, coins, cigarettes, etc., drop from a
bowler’s pocket or fall from a person’s body or clothing. (Footwear and clothing are considered
part of the body.) A player should request permission to cross the foul line to retrieve any items
that have fallen beyond the foul line
Q. Is a foul called when the ball rolls over the foul line during delivery and the foul detector is activated?
A. The bowling ball is not considered a part of the bowler’s body. If the bowler did not step on or
go beyond the foul line, a foul is not recorded.
