What defines a moving violation?

A moving violation is defined as an infraction that occurs while a vehicle is in motion. This includes a wide range of behaviors that can compromise road safety, such as speeding, running a red light, or making improper turns. These violations specifically pertain to the operation of a vehicle on the roadway and are treated differently than non-moving violations, which typically involve parking or vehicle registration issues.

The other options refer to aspects of vehicle operation or offenses but do not capture the essence of what constitutes a moving violation. For instance, parking-related offenses are classified as non-moving violations, and while crimes committed by drivers could include moving violations, not all will necessarily fit that definition. Similarly, infractions related only to commercial vehicles exclude the broader category of moving violations that apply to all vehicles. Therefore, option A accurately encapsulates the criteria for identifying a moving violation.
