Under new government plans drivers in England, Scotland and Wales caught using a mobile phone for the first time will automatically receive penalty points.
Previously, motorists in some police force areas could avoid points by taking a remedial driving course. However ministers believe it is not a tough enough measure to deter people from using a hand-held phone while driving.
Figures show that the number of under-age car drivers involved in crashes on Britain's roads has reached the highest level in four years.
Some 91 boys and girls under 17 years old were behind the wheel during accidents last year, according to Press Association analysis of Department for Transport data. This is 30% more when compared to the previous year, and is the most since 103 were recorded in 2011.
