When people obey laws such as expressed by posted speed limits, signs that say "no smoking" and proscriptions not to steal, the behavior is?

The behavior is rule-governed when people behave in this manner. This is because they are allowing the rules, in the form of the speed limit, smoking and stealing signs, to tell them what to do. As a result, the rules have direct control over their behavior, due to people's basic tendency to desire to be law-abiding.
