The police in the United Arab Emirates are now using unusual means to prevent speeding -- signs that look like police cars.

It's actually just a flat sign of a police car that appears from the front to be the side of a real three-dimensional car with its lights flashing at the side of a road.

And apparently it's working as the person who captured the image stated "It was shocking moment for me. I thought it was a real police car so immediately I fastened my belt and lowered my speed. When I turned around, [I realized] it was a joke."

My sources tell me that about a mile down the road a real police car was waiting to catch speeders and the officer inside was overheard saying "This is gonna be great!"
