If you witness someone on their phone whilst driving, are you supposed to do anything about it....would you do anything about it or leave it to the police to do their job....
It's unlikely that an individual would be prosecuted for driving whilst using a mobile telephone in a case where the evidence comes from a non-police officer.
However, there is nothing to stop you from reporting the matter to the police.
The law on this is being strengthened. The police will soon be examining the phones of any driver involved in an accident even if they are 100% blameless and checking to see if the phone was used while driving. This can be found from the tracking device in every mobile. If it is found to have been so used the driver will be prosecuted. 6 points and a fine.
