My police career started with the former State Police. The banner below refers to a website with many historical facts from that department. It is in Dutch 

 

The General Traffic Service was a nationally operating department of the former State Police. This service has had a unique fleet for many years. The Porsche was the figurehead of the service and determined the image of the state police for the general public. An extensive overview of the fleet can be found on this website

 

On this site you will find a very extensive photo overview of vehicles, that have been used by the Dutch police over the years.
