How many steps are you allowed after you catch the frisbee in ultimate frisbee?

The given limit is 3 steps, in a straight line. But if you are moving at considerable speed then it's acceptable that more may be needed, a sporting agreement!

However, if you move in an arc or turn as you come to a stop, this is considered traveling and can be called as a foul.

In the newest version of the rules there is no established step number, it is a self call but a travel will be called if you go an unreasonable amount of steps, I believe the rules state something like as many steps need to slow to a stop
