The primary goals of the Traffic Safety Unit are to gain voluntary public compliance with traffic laws, and to reduce the frequency and severity of traffic collisions.
The TSU supports national programs and campaigns such as "Safe Communities", "Click It or Ticket", "Drunk Driving – Over the Limit, Under Arrest" and "Shattered Dreams". These programs bring elements of KPD and the community together, such as enforcement, business, health and education; to prevent injuries. A part of this group is the Keiki Injury Prevention Coalition which is involved in reducing the number of non-intentional injuries involving children.
