In Texas you are required to inform the officer, else its a crime (misdemeanor though I think). I think you have to actually present your CHL license at the same time. Further, in Texas, when they run your driver's license the CHL will come up.
You MUST know the laws of the jurisdiction you are carrying in.
In states you are not required to notify, it may (or may not) be in your best interest to notify.
A simple traffic stop for a headlight or illegal turn might NOT be cause to notify.
More significant things might be.
Even the police try to imply you MUST notify in a state it is not required in, just be polite.
While irritating a cop is not a crime, they CAN make your day difficult.
