Traffic police in the Thames Valley are awarded points depending on who they pull over, the force has confirmed.
The road policing unit has given its 120 officers "aide-memoire-cards" with a chart apportioning different points for catching different offenders.
They get 10 points for stopping a rapist or robber, but can earn the same number of points by stopping two people not wearing their seatbelts.
Officers are set a monthly target of 200 points.
