Honolulu has become the first major US city to decide to prohibit crossing the road while using your mobile phone.

From October, anyone caught crossing a street or highway “while viewing a mobile electronic device” will face a fine of up to $35 for a first offense. Pedestrians caught multiple times will see their fines rise as high as $99.

“We hold the unfortunate distinction of being a major city with more pedestrians being hit in crosswalks, particularly our seniors, than almost any other city in the county,” Honolulu mayor Kirk Caldwell told a press conference last week.
