Section V - Amendments
Amendment I: The Laser / Shotgun Double Barrel Rule
A person may call "laser" or "Shotgun Double Barrel" after shotgun has been called, to override the shotgun call. This is only valid if the driver verifies the call as we see in Section 1.3.
Additionally, any passenger who says "No Blitz" after claiming shotgun, may not have it taken away by either the "Laser" or "Double Barrel" rules.
These rules hold no precedence over Standard shotgun procedure, and the driver has final say in all calls.
