Despite not being fully self-explanatory in conveying warnings and safety-related information, the pictograms evaluated in this research provided good insight into the different levels of driving risks, especially the rating model pictogram, because respondents' intentions to change their driving behaviors increased with higher categories of risk. The added value of the side-text in the rating model pictogram was not confirmed in this research. Pictograms can be seen as a valuable means to reinforce both written and spoken information given to patients by health care providers at the time of consultation.
