The study evaluated six candidate symbolic signs which could be used for these truck routes. A sample of the general public was used in tests of visibility, meaning, and preference. A sample of truck drivers participated in tests of recognition time, meaning, and preference. The study findings indicate that a side-view, double-trailer sign had the best recognition time, and the best meaning scores. Even though in the visibility study it did not have the longest recognition distances, no other truck was labeled as an oversized truck as often as the double-trailer sign. A good possibility exists that the other candidate signs may be confused with the presently used NO TRUCKS sign. Finally, both truck drivers and the general public overwhelmingly preferred the double-trailer sign over the other candidate signs.
