Is the secondary road network also policed?

The secondary road network is also policed, but enforcement on 30 km/hour roads is limited. In 2016, out of almost 8 million speed fines, only 5,467 (or 0.1%) were issued for offences in 30 km/hour zones. The Public Prosecution Office takes the view that, when a 30km/hour zone does not meet the design requirements, police should be hesitant to correct this by means of traffic enforcement. If a 30km/hour zone is basically well-designed and violations occur nonetheless, police may decide to indeed enforce the rules.

An MUConsult field study [68] argues that speed checks in urban areas are more effective than checks in rural areas; one of the reasons being that urban speed violations are less socially acceptable than rural speed violations.
