The larger-than-life ads were plastered on no fewer than 30 trucks spread across Moscow's roads.

A sexy mobile advertisement featuring a woman's breasts is being blamed for causing over 500 car crashes in one day. The larger-than-life inadvertent distracted driving ads were plastered on no fewer than 30 trucks spread across Moscow's roads.The specific purpose of the ad campaign – designed by an advertising agency specializing in mobile ads – was to draw attention to the mobile billboards. The sparse text in the ad translates from Russian to "They Attract." They certainly do!Russian motorist Ildar Yuriev says, "I was on my way to a business meeting when I saw this truck with a huge photo of breasts on its side go by. Then I was hit by the car behind who said he had been distracted by the truck. It made me late and left my car in the garage, and although I am insured I am still out of pocket."Drivers across Moscow were quick to vocalize their outrage and have reportedly unleashed their anger on AdvTruck.ru, the agency responsible for the stunt. A spokesperson for AdvTruck says "'We are planning to bring a new advertising format onto the market, encouraging companies to place their ads on the sides of trucks, as we thought this would be a good alternative to putting them on the sides of public transport. We wanted to draw attention to this new format with this campaign" he explained.He then added "In all cases of accidents, the car owners will receive compensation costs from us that aren't covered by their insurance."The ad campaign, however tacky, obviously did the job it set out to do, but it left a city full of carnage in its wake, as no fewer than 517 collisions related to the mobile billboards have been officially reported.
