If you are standing at a danger aspect and decide to contact the signaller you are (in most cases) told to "Proceed as signals indicate", this can be quite an ambiguous message as it says proceed, which can be taken to mean, cleared to pass signal (x) at danger, follow all other aspects (as is the case in reality). However, if you do, the game will end with the SPAD message. I propose that the message should be changed to "Denied, wait until signal clears" or "Cleared to pass signal at danger, obey all other aspects".
