No. You can't charge someone with perjury at a traffic stop.

#Long Answer

Perjury is a criminal offense, not a claim that can be brought by a private individual in a civil action. Prosecutors charge people with perjury and other crimes if they find that there is probable cause to do so. Perjury consists of lying about a material matter under oath or under an affirmation or declaration made under penalty of perjury.

Generally speaking, a statement made to someone at the scene of an auto accident would not constitute perjury, even if it was intentionally false regarding a material matter, although a false statement to a police officer could constitute the lesser crime of making a false statement to a police officer. Sometimes an written accident report is prepared and signed by someone involved in an accident under penalty of perjury, but this would usually be stated clearly on the written document if that was the case.

Private individuals can't charge anyone with any crime or ordinance violation, including perjury, in most jurisdictions in the U.S. There are a few exceptions (mostly on the East Coast).

Law enforcement officers also don't determine the percentage by which someone is at fault, That is the job of a judge or jury in a civil trial.

Law enforcement officers can issue traffic citations to anyone whom they believe they have probable cause to believe committed a traffic offense, and a court will determine if a traffic offense was committed if there is not a guilty plea.

Law enforcement officers can also arrest people if they have probable cause to believe a crime subject to arrest was committed, and if the prosecutor agrees and decides it is worth the effort, the prosecutor can file criminal charges.

Private individuals can report suspected crimes to law enforcement (or directly to a prosecutor) and can ask to "press charges", but the decision to press charges is ultimately reserved to the prosecutor.

Dashcam videos can be admissible evidence in either a lawsuit arising from an automobile accident and in a criminal trial, if duly authenticated and if disclosed in advance of trial where court rules require that it be disclosed.
