'Screaming' traffic cones unveiled in Birmingham
"Intelligent" traffic cones are being unveiled on the M6 in the West Midlands in a bid to improve road safety.
The cones are similar to regular ones but have a yellow top and look like a lighthouse.
The in-built alarm "screams" when the cone is struck, alerting workers to the possible danger of a vehicle coming too close to them.
Phil Mackie reports.
