Previous studies have investigated audio, visual and tactile driver warnings, indicating the importance of communi-cating the appropriate level of urgency to the drivers. How-ever, these modalities have never been combined exhaust-ively and tested under conditions of varying situational ur-gency to assess their effectiveness both in the presence and absence of critical driving events. This paper describes an experiment evaluating all multimodal combinations of such warnings under two contexts of situational urgency: A lead car braking and not braking. The results showed that partic-ipants responded quicker to more urgent warnings, especial-ly in the presence of a car braking. They also responded faster to the multimodal as opposed to unimodal signals. Driving behaviour improved in the presence of the warn-ings and the absence of a car braking. These results high-light the influence of urgency and number of modalities in warning design and indicate the utility of non-visual warn-ings in driving.
