A. In a charge of violating a speed restriction in this article, the complaint shall specify all of the following:

B. The provision of this article declaring maximum speed limitations does not relieve the plaintiff in any civil action, other than a civil action to impose a civil penalty, from the burden of proving negligence on the part of the defendant as the proximate cause of an accident.

C. If a person is charged with a criminal offense, except for excessive speed under § 28-701.02, or cited for a civil traffic violation under this article and if the person is operating a commercial motor vehicle as defined in § 28-3001, the court, on conviction of the offense or on adjudication of the civil traffic complaint, shall make a finding based on either an admission or the evidence as to whether the speed that the vehicle was operated was fifteen miles per hour or more over the speed limit.
