An advertisement showing a woman's bare breasts has reportedly caused more than 500 accidents in one day in a poorly-thought out PR campaign, British media report.
The photograph showing a woman cupping her breasts with a thin blue strip across the nipples was posted on the side of 30 vans in Moscow, Russia.
The advert simply read: 'They attract'.
But as the vans drove around streets in the city, cars started colliding with one another in their wake. It is thought 517 accidents happened in total.
Ildar Yuriev, 35, was one of the motorists affected.
He said: '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.'
Sarafan Advertising Agency, the company that organised the sign, said it would pay compensation to all those who crashed.
