Sustainable Road Safety implies that the traffic environment is designed to rule out serious crashes and to mitigate the severity of the crashes that do happen. The human dimension is the primary focus: man who is vulnerable, makes mistakes and does not abide by the rules.

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.

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 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.

The elderly have a higher than average fatality rate in traffic. The most important cause of this high fatality rate among the 75 year olds and older is their greater physical vulnerability. In addition, functional limitations can lead to the elderly more frequently being involved in certain types of crashes.
