title: Visibility of smoking warning on cigarette billboards.
abstract: Prevention of morbidity and  mortality related to cigarette smoking has chiefly relied on public education including the Surgeon General's smoking warning on cigarettes and cigarette advertising. The visibility of smoking warnings on cigarette billboards is evaluate under static and dynamic conditions. Temporally, the cigarette brand name was found to be visible at least 17 times longer than the smoking warning. Under many conditions it is questionable if the warning is at all visible to the motorist. By coupling regulations of the smoking warning size to the brand name size, visibility would be better ensured.
