    This article describes a study on the use of pictograms on variable message signs to provide driver information. Interpretation of pictograms varies between high comprehension and obscurity. Data was collected in six countries, England, Finland, France, Germany, Greece and the Netherlands. Various pictogram signs were chosen and drivers questioned as to whether they understood the message and whether the pictogram or a text message would be better. Many of the signs seemed to be open to misinterpretation and it was found that signs were more likely to be correctly interpreted if presented in context. The text message was more clearly understood, and the red triangle seemed to be understood as a warning sign by most drivers.
