KIA’s ‘Optical Illusion’ Ads Warn of the Hidden Dangers on the Road

German advertising agency Gürtlerbachmann created these ‘optical illusion’ ads for car brand KIA to warn drivers of the hidden dangers on the road.
Created with black-and-white diagonal lines, the ads will make you do a double take as they deceivingly spell the words ‘rock’, ‘tree’, and ‘deer’ out.
Are you able to spot the hidden words?
