Traffic violation or a moving violation is any violation of the law committed by the driver of a vehicle while it is in motion. The term “motion” distinguishes it from other motor vehicle violations, such as paperwork violations (which include violations involving automobile insurance, registration and inspection), parking violations, or equipment violations.

While some violations, like parking violations, are civil matters involving a vehicle’s owner, moving violations are charged against the actual driver.

Moving violations are usually classified as infractions or misdemeanors, but serious violations such as hit and run, driving under the influence, and road rage can be considered felonies.

The most commonly enforced moving violation, and the overwhelmingly most frequent reason for a vehicle pullover, are violations of the speed limit. Measurements of motorist speed throughout time have found many roadways where compliance with speed laws is very low, making many motorists liable to be pulled over at the discretion of law enforcement.
