INQUIRER: At 4 p.m. today Mayor Nutter is slated to sign a bill that would ban the use of hand-held cellphones while driving, as well as bicycling or skating. First-time offenders would get hit up with a $150 fine, with a $300 fine for second offenses. The law will go into effect immediately, but the city will delay enforcement while it launches an information campaign of unspecified duration, a spokeswoman said. Citing a Harvard University study, the National Safety Council estimates that drivers using cell phones are about four times more likely to get into a wreck. Five states, including New Jersey, have outright bans. MORE
