The reviled but rampant ritual of gabbing on handheld cell phones while driving, skating, or cycling is about to become illegal in Philadelphia, as Mayor Nutter is expected to sign a bill in the next few days that will make the city's ban perhaps the most far-reaching in any large urban area. But will it make life safer and saner for everyone on Philadelphia's streets?

"This is a realistic, enforceable bill that will save lives," City Councilman William K. Greenlee said before the 17-0 Council vote yesterday. Handheld use, including texting, is also outlawed for skateboarders, bicyclists, in-line skaters and scooter riders - making this likely the most inclusive law in the country. Greenlee and Councilmen Bill Green and Frank Rizzo were behind the measure. Enforcement would begin immediately.

The new ordinance fines first-time offenders $150; a second offense draws a $300 fine.

The Philadelphia law includes exceptions for calling 911 or reporting a traffic accident or an unsafe driver. Police and other workers can talk into a handheld device in connection with work, and anyone can use a handheld if parked off the street.

Critics say handheld cell phones are not the problem - it's drivers distracted by cell-phone conversations who cause many accidents.
