According to fairly comprehensive research, yes it is. I struggle to see how it would be policed though. I often say to any passengers I'm carrying, that if I go quiet, I'm not being rude. My view is that anyone caught using a handheld device while driving, including stopped at traffic lights should receive six points and be fined £250. Texting whilst driving is far worse. Anyone causing death while using a handheld, should, in my view receive a band from driving for life and an immediate custodial sentence.
