Abstract

This study was conducted to assess comprehension of existing road hazard communication designs (RHCDs) in relation to culturally adapted ones among commercial vehicle drivers using a two-part study design. In Study One, nine participants were recruited and their comprehension of twenty existing RHCDs was tested.

RESULTS of the analysis revealed that only 50% of the designs met the acceptance criterion of 67% set by the Organization for International Standardization (ISO). Culturally adapted symbols were then developed for the ten symbols which failed to meet the ISO acceptance criterion through a longitudinal focus group discussion involving nine participants. In Study Two, 226 commercial vehicle drivers were drawn from four bus terminals.

RESULTS of the paired samples t test performed showed that comprehension of the culturally adapted designs was significantly better than the comprehension of their equivalent existing designs. The findings were discussed in the context of extant literature and practice.
