    Parents usually teach their children how to cross the street safely, by looking both ways for cars.{#blank#}1{#/blank#}The city of Honolulu, Hawaii wants everyone to learn that lesson.

    {#blank#}2{#/blank#}Beginning on October 24, you will be fined from $15 to $99 if you step into a Honolulu street while looking at your phone. Honolulu is the first major U.S. city to ban what is called "distracted walking". It recently passed a law in a seven to two vote. The law says, "No pedestrian shall cross a street or highway while viewing a mobile electronic device."{#blank#}3{#/blank#} 

    The law includes all electronic devices with screens: cellphone, tablets, gaming devices, digital cameras and laptop computers.{#blank#}4{#/blank#}Pedestrians may use such devices in the street to call emergency services and rescue workers, such as firefighters and police officers.

    Pedestrian deaths have been increasing as the use of cellphones rises. The Governors Highway Safety Association, or GHSA, says pedestrian deaths in the United States increased 25 percent between 2010 and 2015. That trend continued in 2016 with the number of pedestrian deaths rising to almost 6000, 11% higher than in 2015.

    {#blank#}5{#/blank#}The state of Washington was the first to outlaw distracted driving back in 2007. Now, 46 other states as well as D. C. Puerto Rico, Guam and the U. S. Virgin Islands, have laws against texting while driving.

    If you still want to text while walking, you could avoid being fined in Honolulu by using a voice-controlled digital assistant such as Siri or Google Assistant. Or you could just wait until you are again, safely, off the street.

B. Other U. S. cities may follow Honolulu.

C. But do they also teach them to put away their cellphones?

D. Texting while crossing the street will soon be banned in the city.

E. Do you like Honolulu's new law that bans texting while walking?
