A travel infraction occurs if:
The defence should not call travel under section 18.2 unless they have evidence that the player was not trying to stop while in possession of the disc. In particular: - a player who catches and throws the disc while entirely in the air does not need to slow down - the length of a player's strides should decrease as they slow down - a player is not allowed to maintain a constant speed while catching and throwing the disc, unless they catch and throw in the air - it should never take a player more than 5 steps to come to a stop Unless the defence has evidence along those lines, they should not call travel. Players should also take into consideration that a player may change direction after they have established a pivot -- any change of direction after a pivot has been established should not be called a travel. In some situations, a receiver may need to maintain speed briefly or change direction slightly to avoid contact with a diving defender or to jump over a player on the ground. This is expected in such situations and should not be considered a travel. If the travel is caused solely by contact that is initiated by an opponent, this should not be considered a travel. If play has stopped, the thrower may change the part of their body that they have in contact with the pivot spot. This is not a travel.
the thrower fails to maintain contact with the playing field throughout the throwing motion; or
