Consent is implied via an affirmative action - something that can't be mistaken as acceptance. At the checkpoint, that's placing your items on the belt for inspection. When you get a DL, it's a signature on the app with an acknowledgement that consent is given to check for BAC if there's reasonable suspicion that a driver may be drunk.

Simply placing a sign in a public area saying an organization is going to be searching doesn't give an opportunity for an affirmative action for implied consent.
