We are proud to have been recognised as an outstanding CLOCS Champion for “outstanding commitment and positive action in ensuring the safest construction vehicle journeys across our organisation and the wider sector.”
The Construction Logistics and Community Safety (CLOCS) standard aims to reduce the number of traffic incidents related to construction logistics and protect vulnerable road users. Over the past few years, we have been collaborating with CLOCS to promote and adopt its principles through in-house training and courses.
We recently supported the CLOCS Works campaign to raise awareness of the CLOCS standard among local authorities so that we can work together on addressing those hazards and reducing the number of people injured or killed on British roads every year.
Research shows that there has been up to a 47% reduction in casualty rate when implementing CLOCS, so we will continue our efforts to implement it across our sites.
