Real life examples of following the moral law is a hard point for Kant. Specifically, this is because for an action to be moral, it is not sufficient that you do the right thing -- you must also do it from the right maxim (basis for action). Consequently, it is never going to be apparent in the phenomenological world that someone acted from the right sort of basis in doing the right thing.
The contrary cases (actions that clearly violate the moral law) is not equally difficult. There are some actions that Kant considers utterly incompatible with the moral law: murder, lying, cheating. Thus, any time there is a murder or a lie, it is clear that these cannot be motivated by the moral law (as Kant understands the term).
For more on this topic, I would recommend Kant's Metaphysics of Morals. You can find Kant delineating this in the preface and in the Doctrine of Right a.k.a. Metaphysical Principles of Justice. (= German, Rechtslehre). The Doctrine of Right looks at what we should make law and what we can obligate others to do. The second part, the Doctrine of Virtue (= German , Tugendlehre) looks at what it takes for our actions to be moral. The former is a good guide for where Kantians think you can find examples of not following the moral law. But examples of following the moral law are harder precisely because their accomplishment includes but is not limited to doing the right thing.
