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.
a player purposefully bobbles, fumbles or delays the disc to themselves in order to move in any direction.
Any contact with the disc that is not a clean catch can be considered tipping (the rules also use the terms bobbling, fumbling, and delaying).
If a player intentionally tips the disc to themselves into the endzone so that they can score, this is a travel infraction.If a player tips the disc so a team-mate can catch it in the end zone, this is a goal.
If a player fumbles with a disc while catching it and finally manages to get control over it in the end zone, this is a goal, unless the fumbling was intentional.
If they tip the disc solely in order to assist themselves to catch a disc that they otherwise would not have been able to gain possession of, that is not a travel.
