Note
Once in stop-time mode, should there be a difference of 6 goals, the clock shall be run in straight time. Once the goals drop to 4 goals, the clock shall be changed back to stop time. This rule has been adopted by the GELC and CDLA, but not the ALRA.

These rules do not apply to major lacrosse (i.e. Tier I and Tier II Junior).

When to Stop the Clock
In Junior Tier II and below, the clock shall be stopped for any dead ball. A dead ball is defined as a stoppage in the game for a penalty, a goal, a time out, or an injured player. For any other stoppage in play (a possession call, for example), the clock shall continue to run.

In Junior Tier I, the clock shall be stopped for any stoppage in play, whether it is a dead ball or not.

Shot Clock
The shot clock will be in effect for the leagues of Novice and up.
