In the Netherlands, a sustainable road safety approach, in which measures in the fields of Engineering, Education and Enforcement (3Es) are complementary, has been used for decades. Enforcement reduces high-risk road user behaviour and is therefore an important component of this safe system approach.

Driver fatigue is estimated to be a (contributing) factor in 15 to 20% of crashes, but estimates in individual studies vary widely. Drivers who are tired are less attentive and react less quickly and less adequately than drivers who are not tired. They also get irritated and frustrated more easily.
A bicycle helmet is intended to protect cyclists against head and brain injuries when they are involved in crashes. The helmet does not prevent bicycle crashes (see the SWOV fact sheet Cyclists for general bicycle safety measures). International research shows that in case of a crash helmeted cyclists are 60% less likely to sustain serious head/brain injuries and 70% less likely to sustain fatal head/brain injuries than cyclists not wearing a helmet.
Visual information is of the utmost importance to road users. In darkness, both public lighting and vehicle lighting help road users take stock of the traffic situation and help them to be seen by others. Installing public lighting leads to a 50% reduction in the number of nighttime injury crashes. Disavantages of public lighting are, among other things, the risk of collisons with lamp posts, light pollution and the costs of material, maintenance and energy consumption. The road safety effects of a reduction in illuminance level on motorways vary according to the traffic situation.
Moped and light-moped riders are at relatively high risk of being a crash casualty. Although there is a trend towards fewer deaths, in the Netherlands, the risk of being killed or seriously injured remains very large compared with other modes of transport. In the Netherlands, helmet use is mandatory for moped riders, but not for light-moped riders. In recent years we have seen a strong increase in the number of light mopeds (especially the scooter model is widely sold), whereas the number of mopeds has been decreasing slightly.
A progressive penalty system encompasses heavier or more far-reaching sanctions being imposed as one commits more offences. A progressive penalty system is often called a progressive fines system if it involves increasingly higher financial penalties (fines), but (other) recidivism schemes such as demerit points systems can also be seen as a progressive penalty systems.
In the past ten years (2006-2015) an average of 11 road deaths per year in the Netherlands was registered in crashes involving agricultural vehicles. Compared to the early 1990s, the average number of road deaths due to crashes involving an agricultural vehicle increased from 1% to 2% of the total number of road deaths in the Netherlands. Agricultural vehicles are defined as agricultural and forestry tractors as well as self-propelled machinery used in farming, construction industry, civil engineering and the maintenance of public green spaces.
In 2015, 47 motorcyclists died in traffic in the Netherlands. After 2009, when their number was approximately 1,300, it has not been possible to reliably determine the number of serious road injuries due to poor registration. In the Netherlands 1,4 million people have a motorcycle licence, but as there are 656,000 registered motorcycles, less than half own a motorcycle. These motorcyclists travel an average 1,200 to 3,400 km per year, which means that most do not really build a routine.
