2.4.2 A jam may last up to two (2) minutes. Jams end on the fourth whistle of the jam-ending signal (see Section 2.9 - Whistles).

The length of jams is very well known by almost anyone in the derby world, and those who don’t know learn very quickly. What is sometimes misunderstood, albeit very uncommonly, is that jams end on the 4th whistle of the jam-ending signal. The jam-ending signal is 4 rapid whistle blasts. Up until the 4th whistle points may be scored and penalties issued.
