Many of the principles listed in the LEARN! Key Principles are low-cost measures. Schools can, for example, develop and implement a traffic safety policy plan and appoint a traffic safety contact teacher (see Principles #6 and #7) at little to no cost.
The principles of materials needing to be up-to-date (see Principle #10) as well as covering more than solely knowledge (see Principle #9), can be used as assessment criteria when choosing new educational materials, as can Principle #14 on using interdisciplinary material as a means for pupils to learn about traffic safety and mobility education while teaching other subjects. The LEARN! Manual furthermore translates these (and other Key Principles) into guidelines reflecting minimum criteria for qualitatively sound education material.
