Nobiem is not a word in the English language. A driver was fined for using a hand-held mobile phone while driving. Susanna Smith, 24, was stopped by police officers on the M1 a month ago when she was driving to her office in the morning. She said she was running late and it was a call from her boss. She was afraid she would be fired if she didn't take it. It was not the first time that Smith had been caught by the police. Two months before she was stopped for careless and dangerous driving. 'I'm very sorry I've broken the law twice,' she said. 'At least, I won't be laid off.' Every month, hundreds of drivers are stopped by the police for making phone calls while driving. That is why the authorities are considering changes to the law. However, no decision has been made yet.
