We all know it's against the law but thousands of drivers in the south-east are still using their mobile phones behind the wheel, making calls, texting, and even taking pictures.
In Sussex last year, more than 1,800 drivers were caught using a phone while driving. And in Kent, more than 1,000 drivers were given penalties in 2014.
Now a trial has started in Sussex of an "intelligent lamppost" that can detect when a phone is being used in a car - and it flashes a warning - telling you to stop doing it.
But will it work? David Johns investigates. He speaks to Carl Knapp of the Sussex Safer Roads Partnership; Peter Rodger of the Institute of Advanced Motorists; and sign manufacturer Tim Barnett.

It may be hard to imagine now, but there was a time when there were no mobile phones. Thirty years ago this week, the first ever call from a huge transportable device was made in the UK, on the Vodafone network - now one of the region's largest employers. A few examples of the metal monster still exist, so we asked some schoolchildren what they made of them...
Officers from the Hampshire and Thames Valley Joint Operation Unit have begun a week long operation targeting people who use their mobile phones while driving.
