Drivers could face up to a month in jail or a fine of as much as £1,000 if they use social media to warn other motorists where mobile speed cameras are.
According to the police, posting messages on the likes of Twitter and Facebook to alert others can be seen as a criminal offence and people can face prosecution.
The warning comes after a motorist in Wales posted the location of a speed camera van on Facebook. He was urged to take it down by other users, North Wales Live reports and, in another potential driving offence, he had posted a photo of the speed trap he had taken while passing.
