The Highways Agency is harvesting information from the devices as part of a project to monitor traffic flow and ease congestion.
The information is being passed on by mobile phone companies and other data firms so the agency can identify areas of heavy traffic and help motorists avoid them.
The agency says that all the information it receives is processed and anonymous so that the movements of an individual motorist cannot be identified.
