Meaning in Motion: A Semiotic Study of Traffic Signs in Davao City as the Language of Road Communication

Abstract

This study investigates how drivers who have completed the Theoretical Driving Course (TDC) and Practical Driving Course (PDC), and those who have not, interpret traffic signs, pavement markings, and other road symbols within the road context of Davao City, Philippines. It explores how meaning is constructed and translated into driver compliance, viewing the road as a communicative field shaped by signs, culture, and interpretation. Guided by the semiotic theory of Ferdinand de Saussure (1916) and Yuri Lotman’s (1990) concept of the semiosphere, this qualitative study analyses how drivers and motorcyclists engage with both the mechanical and the semiotic language of the road. Data were generated through two complementary methods: focus group discussions (FGDs) with 12 purposively selected participants comprising TDC-PDC-trained and non-TDC-PDC drivers and motorcyclists, and live roadside interviews conducted with drivers navigating the actual roads of Davao City. The roadside interviews were essential in capturing how material traffic signs embedded in their physical environments, encountered under real driving conditions, and shaped by their visibility, placement, and spatial context, carry semiotic weight that abstract depictions cannot fully replicate. Findings reveal that formally trained drivers exhibit higher levels of semiotic awareness, interpreting colours, shapes, and symbols not merely as functional cues but as signifiers within a shared system of meaning. In contrast, untrained drivers relied more heavily on habit, intuition, and experiential knowledge, which emerged as a mode of engagement termed as folk semiosis. Crucially, however, folk semiosis is not the exclusive domain of the untrained drivers; even formally trained drivers negotiate this intuitive, experience-driven mode of sign-reading when navigating unfamiliar roads and terrain, where it functions additively to discipline and interpretation, sharpening alertness, deepening caution, and enriching their already-established semiotic competence. This study concludes that the road is not merely a space of transit but a living semiotic ecosystem where meaning, disciplined behaviour, and safety continuously intersect. Nonetheless, while untrained drivers who exercise genuine caution and self-taught discipline through folk semiosis can contribute meaningfully to orderly and smooth traffic flow, they must ultimately recognise that formal TDC and PDC training remains indispensable, not only for a deeper, legally grounded understanding of road and traffic signs, but for the fuller, more conscious participation in road safety that semiotic education can reliably produce.
