I know it isn’t, but the amount of drivers I see daily doing this makes me think it is. They’re so blatant that they either don’t know it’s illegal or don’t care. I suspect the latter. It’s not just cars or unmarked vans either as I see at least one major utility van driver a day blathering away or texting as if they don’t have a care in the world. What’s the point of regulation without enforcement?
To be a litle pedantic about it your heading is correct, with the proviso that it is being used hands free. However I agree with your observation that there are numerous instances of car, van and truck drivers all holding a phone to their ear as they drive. And Woodchip is right, how do you police it on a large scale? Once upon a time it was acceptable practise to drive without wearing a seat belt and also to have several drinks before driving but national campaigns on TV, newspapers, bill boards etc. made it socially unacceptable to do so. We need a similar campaign for hand held mobile phones in vehicles.
In 2006, there were 170,000 convictions for driving while using a mobile phone. The following year over 185,000 motorists were prosecuted. The likelihood is that millions of drivers get away with it however, because Police must catch you in the act of using the phone.
Of course the real answer to the problem is to ban the use of phones in moving vehicles altogether. If this was to happen the world wouldn't come to an end, and a lot of people would avoid being injured or killed in phone-related traffic accidents.
