Truckers are being alerted to crime on the roads by text messages from police in the first campaign of its kind in England.
West Midlands Police hope the system will reduce crimes against hauliers, such as the theft of loads, and provide the force with extra pairs of eyes and ears on the region's roads.
Information contained within the text messages, which are sent from police to industry contacts and then rolled out to drivers, include details of stolen vehicles and crimes in the area as well as warnings.
Detective Chief Inspector Carl Foulkes, spokesman for the initiative, said the Promptext system had been trialled by officers and drivers for several months before its formal launch.
He said: "While the number of the HGV offences across the region remains low when compared with the total number of vehicle crimes, the cost is disproportionately higher.
"We have worked closely with partner agencies such as the Road Haulage Association and Securitas and have introduced the new Promptext system to work towards making the industry safer."
West Midlands Police is working with neighbouring forces as well as the National Criminal Intelligence Service and Central Motorway Police Group to target offenders.
