In 2020, over a quarter of the total number of bicycle kilometres were cycled on pedelecs; particularly the over-65s opt for pedelecs. This is also borne out by the crash figures: in 2019 and 2020, almost one in three of the cyclist fatalities was a pedelec rider.

Adolescence is the period between childhood and adulthood. Compared with older adolescents (18-24 years old), young adolescents (10-17 years old) exhibit more risky behaviour.  Because of their physical and mental development, young adolescents are attracted  to risky challenges, they are more susceptible to peer pressure, and they have less self-control and overview than older adolescents. This is also reflected in their road use. In comparison with other age groups, young adolescents, boys in particular, die relatively more often of unnatural causes; this largely comprises road crashes.

Traffic education is defined here as any kind of formal or informal education that is aimed at learning and improving the knowledge, insight, skills and attitudes that are necessary for safe traffic participation, including the wish to safely participate in traffic.

Public service advertising (PSA) on road safety does not seem very effective on its own. PSA campaigns mainly influence behaviour when they are combined with police enforcement and rewarding or other actions. This does not mean that PSA campaigns should not be undertaken. Public service advertising can increase knowledge and lead to attitude change and can strengthen support for effective but unpopular measures. A PSA campaign is more effective as the target group is more committed to the issue. Mass media campaigns are usually less effective than local, individual programmes.

In this factsheet wrong-way driving is defined as ‘a car driving in the wrong direction on a road with separated driving directions and consequently driving into oncoming traffic '. This relates mainly to motorways. Wrong-way driving crashes are rare. The outcome, however, is often severe. Most wrong-way driving crashes occur when a driver enters a motorway exit ramp or when a driver reverses direction on a motorway. Orientation problems (especially among the elderly) or recklessness (especially among young drivers) are the most common causes.

In the Netherlands, licence acquisition courses for category B (passenger cars) are concluded by a theoretical and a practical test. Driving lessons are not obligatory, but without them passing the practical test is virtually impossible. For practical reasons, the effectiveness of drivings tests and driver training is hard to assess in a scientific way. A few studies of the effectiveness of theory tests and practical driving tests are indeed available. These do, however, not show a marked relation between crash risk and driving test performance or driver training.

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.

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.

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.
