During the most recent measurements, in 2022, 2.6% of the Dutch drivers were under the influence of alcohol during weekend nights, which amounts to almost double the lowest percentage of alcohol offenders measured (1.4% in 2017).
In general, crash risk is higher in bad weather than in good weather. Adverse weather conditions are mainly rain, snow/hail, fog, strong winds, slipperiness, low sun and high temperatures.
Public communication on road safety includes all activities and products for a voluntary, lasting change in knowledge, attitude or behaviour. There is little evidence that stand-alone mass media communication is effective in changing behaviour or improving road safety. Research does show that campaigns can contribute to increasing support and knowledge of laws and regulations.
The construction of the road network and road design greatly affect road safety: firstly, because they make certain conflicts impossible or unlikely (e.g., by physical separation of driving directions, separate bicycle tracks, clear roadsides); secondly, because they direct the desired traffic behaviour (recognisability, predictability).
In the Netherlands, over a third of road deaths and well over two thirds of serious road injuries are cyclists. Cyclist fatality risk (the number of road deaths per distance travelled) is more than eight times higher than fatality risk for drivers, but over three times as low as that for motorised two-wheelers.
Every year, about 140 fatal 'run-off-road crashes' involving motor vehicles (excluding two-wheelers) are registered in the Netherlands: they result in around 160 road deaths, more than a quarter of the total number of road deaths.
The social costs of road crashes in the Netherlands in 2020 are estimated at € 27 billion (between € 15 and € 36 billion). This is significantly higher than other traffic-related social costs such as traffic congestion (€ 3.5 to € 4.6 billion) and environmental damage (€ 7.3 billion).
In the Netherlands, an average of 24 youngsters aged 12 to 17 are killed in traffic, most of whom are cyclists. After suicide, road crashes are the second most important cause of death of youngsters aged 10 to 19.
Wrong-way driving crashes are infrequent, but their outcome is often serious. Most wrong-way driving crashes occur when drivers inadvertently enter a motorway exit or when drivers turn around on a motorway.
