Road accidents can be prevented by taking effective measures by both individuals and the government. With that initiative, the state departments of transportation in US have come up with creative billboards designed by award-winning ad agencies. Effective ads in out of home (OOH) media are posted by state departments of transportation on behalf of safety. Government-sponsored multi-media campaigns are focused to reduce traffic deaths and injuries which categorically define billboards as part of its comprehensive traffic safety public information program. Denver-based ad agency Amelie Company produced billboards, bus shelters, wall signs, and bus ads to promote seat belts and warn against driving while high on marijuana.
