A senior policeman with Strathclyde Police, Chief Supt Kenny Scott, has been fined GBP60 and had 3 points added to his driving licence for using his mobile 'phone whilst driving. He was off-duty at the time.
I don't know what the circumstances were in this case, but I find personally it requires some discipline not to reach for the mobile if it rings when I'm driving, but so far I haven't given in to the temptation. Whilst I am in general supportive of the ban it is difficult to believe that simply talking to a passenger (or being talked to by a passenger) is not at least as distracting. I do swig from a bottle of water whilst driving and I have read in the past that people have been fined for this too - so I had better watch out I suppose!
