CLOCS Standard

CLOCS has developed the national standard for construction logistics: managing work related road risk a common standard for use by the construction logistics industry. Implemented by construction clients through contracts, this new standard provides a framework enabling the management of road safety by the industry in a way that can be adhered to in a consistent way by fleet operators.

FORS and CLOCS work together, to keep compliance simple. If you work in the construction industry and operate vehicles, FORS Silver accreditation will ensure you are CLOCS compliant.

A collaborative approach

Eleven separate standards, codes of practice and policies relating to work related road safety were reviewed and brought together into a single common standard. The willingness of organisations to set aside individual positions and to work together in support of a common principle allowed the rapid delivery of the CLOCS Standard.  It represents a united response to improve road safety across the industry and greater social responsibility which will save lives.

Developing and sharing effective practice is vital to keep organisations up to date about the latest standards and procedures currently being applied in their industry in relation to managing road safety.

The CLOCS Standard is supported by a Memorandum of Understanding (MoU) and Terms of Reference (ToR) that build engagement and commitment and articulate roles and responsibilities for implementation.

The CLOCS Team is responsible for monitoring the implementation of the Standard, its effectiveness and future versions.
