HONOLULU - Mayor Kirk Caldwell will sign Bill 6 into law Thursday afternoon. 

The law makes it illegal to look at a cellphone or other electronic devices while crossing a street or highway on Oahu.

The fine will be around $15-$35 for the first violation. It can rise to a price between $75-$99 for a third offense within one year after the first violation.

The new law will take effect on Oct. 25, 2017 - 90 days after Caldwell's signature.

The City Council passed the bill on July 13.
