• Abstract:
  One aspect of the control of hazardous cargo is to ensure that trucks carrying such cargo travel on approved routes. These routes, once chosen, should be clearly marked as permitted routes; conversely, routes not allowing hazardous material movement should be marked with prohibitory signs. This study evaluated six candidate signs in both prohibitory and permissive versions. ; Truck drivers and members from the general driving public participated in the study. Signs were evaluated as to their meaning, legibility, recognition time and likelihood of confusion with other selected symbol signs. Subjects also ranked the candidate signs according to preference. Overall, the study concludes that a symbol consisting of the capital letter HC inside a green (permissive) or red (prohibitory) ring designating permissive or prohibitory routes respectively was, on balance, the most effective sign across the measures utilized in the study.
