Which of the following is not classified as a traffic violation?

The distinction of what constitutes a traffic violation often hinges on established laws and regulations governing vehicular operation and safety. In this context, parent directing traffic in a school zone is not classified as a traffic violation because it generally does not fall under the formal categories of traffic law. Parents directing traffic are often designated to assist with pedestrian safety and manage the flow of vehicles during busy school hours, acting in a supportive capacity rather than as violators of traffic rules.

On the other hand, actions such as running a red light, driving without a seatbelt, and parking in a no-parking zone are explicitly defined violations of traffic laws designed to maintain public safety and ensure orderly conduct on the roads. These infractions can result in citations and fines because they directly pertain to the regulation of vehicular behavior and safety measures that must be adhered to by all drivers.
