But what about using a sat nav whilst driving?
Maybe, comes under "driving without due care and attention" if you are weaving about the road and/or almost drive into the back of someone because you're too busy fiddling with your gadget. Note that this law was perfectly suited for prosecuting badly used mobile phones too.
or eating some sweets or food.
They have cameras for that now. Seriously
Again, cameras but not sure on the legality of that one
What about lorry drivers who use CB Radio's ?
Legal I think. Is R420 here?
What about Police officers driving alone, they answer radio calls whilst driving. So I presume they use there hands for that?
The modern police radios do meet the legal definition of a mobile phone, however there is an exception because they are trained to do so properly.
What about changing radio stations on your car stereo? is that not allowed.
Same as satnav.
The big difference between a phone and a CB / police radio is how they are used. When you use a push to talk radio, it's expected that you say your piece and the other person will respond when they're ready, maybe not immediate because the driver may need to negotiate a hazard. Lines of conversation tend to be short and to the point often with various forms of shorthand which, once learned, make it less distracting and easier to follow. A bit like IRC in some ways.
With a mobile conversation, the other person will carry on gabbing about whatever and will start getting arsey if you don't reply immediately, and that is where the safety issues come into play. While it's possible to make a mobile conversation safe (assuming you are speaking to someone who isn't going to get into a strop when you ask, "stop a minute, I need to overtake this moron doing 40") most people don't and rather than educate people into how to do something safely, this government just chooses to ban it instead. Just like everything else.
