Abstract
The first set of materials of the traffic education box "Doorgaand Verkeer" (Through Traffic) released by the Dutch Road Safety Organisation is available as of 1987. The traffic education box aims at stimulating and facilitating traffic education in the lower grades of secondary education. Besides the mentioned set of materials, the so called start set, two additional sets are being developed. In this report the use of materials is at issue. The report has the aim to answer two questions. The first question is about the sufficiency of the materials. The second question focusses on the usability of the materials from th viewpoint of teachers as well as pupils.
