One U.S. city has passed legislation designed to crack down on distracted walking.

A “Zombie Law” is officially in effect in Honolulu, Hawaii — meaning people who cross the street without looking up from their cell phones can be fined.

People caught texting or not paying attention while crossing the street, can be fined up to $35 by police.

That fine jumps to $99 for repeat offenders.

Honolulu is the first city in the United States to pass legislation targeting distracted walking in a bid to increase road safety.
