I have been using CB radio from early 1982, yes AM CB and went over
to FM CB in about 1984.
Although CB radio is not restricted by the law covering mobile
phones, it is however sill illegal to use a hand held microphone
while driving.
There are many charges that the police can and do bring on offenders;
driving while not in complete control of the vehicle, likely to cause
danger, without due care and attention, in a manner likely to cause
an accident.........the list goes on.
In some ways it is a shame, but the law sees you as not being in
control of the vehicle if you have anything else in your hands that
is not an essential part to the driving of the vehicle.
Enjoy, but be safe. :O)
