The Department of Transport's official stance making hands-free phone calls is that they are a "distraction" and should be avoided.
But the government-funded Transport Research Laboratory has found that even hands-free phone calls make drivers four times more likely to have an accident, with concentration levels reduced for 10 minutes after the call has ended.
The research also showed that drivers making hands-free calls had slower reaction times than those who were slightly over the drink-drive limit.
Some businesses, including the FirstGroup transport company, which employs 135,000, have already imposed their own bans on employees making any sort of phone call whilst driving on company business because of the dangers of doing so.
PC Gary Chance, of Lincolnshire police, said: "Driving is a skill that requires attention at all times. It has to be considered that the use of a mobile, even hands-free, was a major factor in this accident."
Richmond is not the first driver to be jailed for killing someone while using a hands-free phone. In 2003 Michael Leach, 29, was jailed for four years at Exeter Crown Court for a similar offence and in 2001 Roger Murray, a 37-year-old lorry driver, was jailed for 18 months in Ayr for causing a fatal crash while on his hands-free phone.
