Pro-Drive managing director Graham Hurdle believes the Government should now look at the bigger picture of how to use public money to make roads safer, rather than simply investing in technology to enforce December's ban.
He said: 'At Pro-Drive, we are fully behind the new mobile phone law. In fact like many road safety experts we do not believe it has gone far enough. But we do have a concern about the enforcement of the law if it follows a similar trend to speeding.
'If you look at what has happened with speed cameras, the arrival of technology to catch someone going too fast was a positive safety step, making drivers slow down in areas of higher danger, such as near schools, at known accident spots and so on.'
Hurdle added that the mixed reaction to speed cameras was caused because many were positioned in safe areas such as on open stretches of dual carriageways.
'The only objective in many people's eyes is to catch drivers out and generate revenue from fines,' he said.
'My concern is that a significant amount of public money will be sunk into similar technology to enforce the mobile phone law when we should be looking at a better balance of investment to assist with other road safety initiatives.'
