“While studies show the education on road safety in schools does improve knowledge [1], there is no evidence that this knowledge changes the safety level of on-road behaviour [2]. There even is a risk that increased knowledge increases confidence and risk-taking. Even if there were benefits from school-based training, it would require immense resources (funding and skilled trainers) to produce any significant safety benefit in terms of crash reduction [3]” 

That’s an important quote from the excellent document:
