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 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.

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.

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.

A progressive penalty system encompasses heavier or more far-reaching sanctions being imposed as one commits more offences. A progressive penalty system is often called a progressive fines system if it involves increasingly higher financial penalties (fines), but (other) recidivism schemes such as demerit points systems can also be seen as a progressive penalty systems.
