The Construction Logistics and Cyclist Safety (CLOCS) Standard for construction logistics: Managing work related road risk is a common standard for use by the construction logistics industry. Implemented by construction clients through contracts, it provides a framework that enables ownership in managing road risk which can be adhered to in a consistent way by fleet operators.

A series of supporting CLOCS Guides have been developed in collaboration with industry stakeholders and are designed to assist clients and operators in implementing and adhering to the requirements of the CLOCS Standard.

An example of CLOGS being applied is the UK’s Cross Rail Project which is the biggest infrastructure project in Europe.
