Good advice for sure but that advice has always been available to those who would take the time to ask.  A simple visit to your local PD yields the same information & adds an element of engaging with & talking to law enforcement.    

It's important to note that these are guidelines not laws.  Arizona is NOT a must-inform state so while the "guidelines" say you must immediately inform the officer of a weapon in the car you are not legally required to.  This is a democratic lawmaker attempting to backdoor existing laws and hoping to Jedi Mind Trick people into giving up their rights under the law.

I think this is more of a "gotcha" for drivers in AZ than anything else.  Now if someone acts like an idiot and gets shot the department can come back and say the guidelines were in the driving manual and you didn't follow them. Raise your hand if you regularly pull out the 'ol driving manual to see what has changed since you got your license at 16?
