The campaign, which begins on Thursday 24 September and finishes on 07 October, will include increased police patrols across Wales to encourage drivers to think more carefully about the risks and penalties they face if caught using a mobile phone behind the wheel.

With the prevalence of smart phones allowing people to access emails, social media and apps, there has been a marked increase in the use of mobile phones while driving. Distracted driving is expected to be the biggest cause of injury and fatality on UK roads during 2015.

During a similar campaign last year, officers in Wales detected 914 people using their mobile phones while driving. The fixed penalty notice for being caught using a mobile phone while driving is a £100 fine and three penalty points. For serious offences or repeat offenders, a fine of up to £1,000 could be issued or a person could be disqualified from driving.

Anthony Welsh, a serious injury solicitor based in Thompsons Solicitors' Cardiff office, said: “Despite mobile phone usage being banned for more than a decade, an incredible number of people still use their phone when they are behind the wheel including, as we have all seen commercial drivers who as well as putting themselves and other road users in danger are putting their livelihoods at risk.

“Given the injuries and, in some cases, fatalities that driving using a mobile phone can cause to the driver and other road users, we welcome the seriousness with which police forces in Wales are treating this issue.”
