Swedish designers Jacob Sempler and Emil Tiismann created these traffic signs for Stockholm in November 2015.
"One morning when I walked to work, I almost got run over by a car, because I was staring at my stupid smartphone," 29-year-old Sempler previously told Business Insider. "I looked around and realized that I wasn't the only one."
They were installed in three different locations.
"The thing is though, that the people who really need to see this sign, are most likely just gonna pass it with their eyes glued to their screens," he said.
