Search and seizure is covered by the Fourth Amendment, so it is the same in every state.
A frisk, (also called a "Terry Stop", named for the case Terry v. Ohio), can be done anytime the officer has a concern for his safety. Although the intent was to allow the officer to do a pat down for weapons, the Court ruled is other evidence was found, it is admissible as long as the officer's actions were reasonable.
For example, finding a bindle of cocaine in your wallet would not be reasonable, as there is no expectation to have a weapon there. Finding a pot pipe in your front pocket is reasonable, as the front pocket could hold a weapon and the officer would recognize the pipe by "Plain Feel" (Minnesota v. Dickerson), which was expanded from the Plain View Doctrine (Arizona v. Hicks).
BQ: An exterior sniff by a K-9 is legal, as you have no expectation of privacy in the air surrounding your vehicle, but a random search without probable cause is not.
