Which of the following is considered a moving violation in Georgia?

Speeding is classified as a moving violation in Georgia because it involves the operation of a vehicle in a manner that exceeds the legal speed limit while driving on a public road. Moving violations typically pertain to actions taken by a driver while the vehicle is in motion, affecting road safety and traffic flow.

In contrast, parking in a no-parking zone is a stationary violation; it occurs when a vehicle is parked in an area designated as forbidden for parking rather than being related to the vehicle's movement on the road.

Failure to signal, although it may be perceived as a critical driving behavior affecting safety, is often categorized alongside other less serious infractions that may not necessarily warrant the same penalties as more severe moving violations like speeding.

Expired registration pertains to the validity of the vehicle's registration, which is related to compliance with administrative requirements rather than the safe operation of a vehicle on the road. Therefore, while each of these options represents a violation, speeding stands out as a clear moving violation due to its direct relevance to active driving behavior.
