What type of crime is characterized by knowingly and willfully obstructing law enforcement?

The correct classification for the crime of knowingly and willfully obstructing law enforcement is a misdemeanor. Misdemeanors are generally defined as crimes that are less severe than felonies but can still carry significant consequences, including fines and imprisonment for a year or less. Obstructing law enforcement typically falls into this category because it involves actions that hinder police or other legal authorities from performing their duties, which is a serious offense but usually not on the same level as felony crimes, such as violent offenses or major drug trafficking.

Felonies, on the other hand, are more serious offenses that can lead to longer prison sentences and more severe penalties. Infractions are minor violations, often punishable only by fines, and do not typically involve jail time. Traffic violations can encompass a range of infractions but are specifically related to the rules of the road. While obstructing law enforcement is a significant offense, it is more accurately categorized with misdemeanors due to its nature and the legal consequences typically associated with it.
