In the Netherlands, on average, more than 50 people die every year in a submerged vehicle crash. More than two thirds die from drowning. The casualties are mainly car occupants, while cyclist and mobility scooter fatalities are also numerous. Casualties are mostly male and aged 18-24. Despite the large number of casualties, not much is known about possible causes of crashes in which vehicles end up in the water. Foreign studies show that alcohol and drug use, and/or speeding are often involved.

Risky road user behaviour is behaviour that adversely affects road safety, such as driving under the influence of alcohol, drugs or medicines, speeding, inappropriate speed, distracted or fatigued driving, red light negation, and failure to use or misuse means of protection (motorcycle or moped helmet, seatbelt). Younger road users more often display risky behaviour than older road users, and men more often than women.

Driving under the influence of drugs or impairing medicines reduces fitness to drive[i] and increases crash risk. Drugs have a numbing, stimulating or mind-altering effect on the brain, or a combination of these effects, which impair traffic task performance. For drug use in traffic, we (unfortunately) have to rely on research dating back to 2011.

Children are a vulnerable group among road users. They are, after all, still building up skills which will eventually allow them to become safe and independent road users. The role of parents in teaching their children how to behave safely in traffic is very important.  In this fact sheet, children are taken to belong to the age category 0 to 14, unless specified otherwise.

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.

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. The crash type that is characteristic for the elderly occurs while turning left at an intersection.
