Intelligent cat’s eyes are being used on a section of the M8 at junction six, Newhouse, Lanarkshire – part of Scotland’s busiest motorway.

The Intelligent Road Stud will flash to warn approaching drivers about potential incidents. They have the capacity to measure a car’s speed but there are no plans to use the studs as speed cameras; details would be used to help slow down traffic and improving road safety

The studs can also sense fog, rain and ice and help steer motorists through difficult weather conditions.
