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).

A pedestrian fall or collision is only a road crash (pedestrian crash) when a moving vehicle is involved. Between 2010 and 2019, an annual average of 59 pedestrians were killed in road crashes. Between 1999 and 2019, the number of pedestrian road deaths dropped by 62%.

The mobile phone is symbolic of ‘distraction in traffic’. But apart from mobile phone calls, texting, or listening to music, many drivers, cyclists and pedestrians are occupied with all sorts of other activities that may distract them. Examples are: operating the navigation system, eating, drinking, talking to passengers or daydreaming.

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.

Driver fatigue is estimated to be a (contributing) factor in 15 to 20% of crashes, but estimates in individual studies vary widely. Drivers who are tired are less attentive and react less quickly and less adequately than drivers who are not tired. They also get irritated and frustrated more easily.

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.

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.
