Can a detainee who acts suspiciously during a traffic stop, causing the officer to fear for his safety, be searched?

A detainee who acts suspiciously during a traffic stop, causing the officer to fear for his safety, may be searched. (See People v. Superior Court (Brown) 111 Cal.App.3d 948, 954-956 [person stopped to be given a traffic citation behaved peculiarly and resisted the stop; when a pat down search uncovered a gun in his waistband, he could be convicted as a felon in possession of a firearm].) Here, appellant refused three requests to leave his car for field sobriety tests, raised his fists, took a threatening "fighting stance," and was subdued with a taser.
