Virginia Supreme Court Rule 3B:2. Uniform Fine Schedule.

This rule creates a standardized schedule for fines that can be imposed without a court hearing (i.e., fines imposed by a clerk or magistrate after a motorist enters a written guilty plea and waives their court hearing). The rule provides that clerks and magistrates may not impose any fine amount that differs from this schedule, but the schedule does not restrict judges’ discretion in court hearings.
