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. The road environment, vehicles and technology are to offer support and protection in order to make the safety of the traffic system as little dependent on individual actions as possible. Traffic professionals and central government ensure that these conditions are always met and that imperfections are corrected.

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.

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.
