To select the right modality for the interaction between drivers and the in-vehicle information system (IVIS) is crucial for safety reasons. This paper presents an experimental study to dress on this subject. The study was carried out on a 160 degree car-driving simulation lab. There are 10 subjects participated in the experiment. We compared the subjects driving behavior on speech input/output only and speech input with speech+visual output interaction modalities with a simple IVIS. To judge the safety status of subjects’ driving performance, two independent variables which includes the average division of over speed and the average division of the car out of lane were measured as dangerous extent. Result indicates that it is not significant differences of driving performance by using synthetic speech to replace the visual display in the IVIS. It indicated that the visual presentation of a multi-modal IVIS can be acts as redundancy or complementary modality for auditory presentation, which will aids in relieving the resource demand.
