Government legislation states;
"It is illegal to use a hand-held mobile phone or similar device while driving. The penalty is £60 and 3 penalty points. If the case goes to court, it's a maximum fine of £1,000 (£2,500 if driving a bus, coach or heavy goods vehicle), discretionary disqualification and 3 points....
...Employers could also be prosecuted if employees are distracted because they require them to use their mobile phones while driving"
Fitting your business vehicles with fully integarted car kits will ensure that your employees are given the correct tools to abide by the driving laws.
