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.

In the Netherlands, a sustainable road safety approach, in which measures in the fields of Engineering, Education and Enforcement (3Es) are complementary, has been used for decades. Enforcement reduces high-risk road user behaviour and is therefore an important component of this safe system approach.

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.
