Moving traffic violations are violations committed by the driver or operator of a motor vehicle while the vehicle is moving—such as exceeding the speed limit, failing to stop at a stop sign or red light, failing to yield when required, making an illegal or improper turn, or driving under the influence of alcohol or drugs (DUI/DWI).

In contrast, nonmoving violations are usually violations that occur when a vehicle is not moving (parking violations) or not required to be moving (mechanical violations) to constitute a violation—such as expired license plates/tags; parking in front of a fire hydrant, in a no parking zone, or in a place that blocks a sidewalk; a cracked windshield; a broken taillight; or an illegal window tint (too dark).

Laws vary from state to state but the fines and penalties for nonmoving violations are usually less serious than for moving violations. Some nonmoving violations (usually vehicle mechanical problems) that are correctable may be dismissed if the driver fixes the problem within a short, specified period and shows proof the mechanical problem was fixed. And in many states nonmoving violations may not cause penalty points to be added to your driver's license or record.

In Tennessee, moving traffic violations encompass offenses such as speeding, running stop signs or red lights, failing to yield, making illegal turns, and driving under the influence (DUI). These violations occur while the vehicle is in motion and often result in more severe penalties, including fines, points on the driver's license, and potential increases in insurance rates. Some moving violations can lead to license suspension or revocation, especially for repeat offenses or serious infractions like DUI. Nonmoving violations in Tennessee typically involve parking infractions or vehicle equipment issues, such as expired tags, parking in prohibited areas, or having a broken taillight. The penalties for nonmoving violations are generally less severe than for moving violations and may include smaller fines. Some nonmoving violations can be dismissed if the issue is corrected within a specified timeframe and proof of the correction is provided to the court. Unlike moving violations, nonmoving violations in Tennessee often do not result in points being added to a driver's license. However, the specifics of each case can vary, and it is advisable to consult with an attorney for guidance on particular situations.
