The CLOCS Standard is a national industry standard that defines the primary requirements placed upon the key stakeholders associated with a construction project and places responsibilities and duties on the regulator, the client, the principal contractor controlling the construction site and the supply chain including the operator of any road-going vehicles servicing that project.
The CLOCS Standard is the direct result of collaboration between the construction and fleet sectors to address shared issues.
It draws together best practice from across the construction industry to provide an industry standard that can be implemented by the key stakeholders, with detailed requirements for each group to drive a collaborative approach to work-related road risk. Each requirement has been developed with the aim of reducing the risk of harm to the community from construction vehicle journeys.
Clients shall specify whether the CLOCS Standard applies within contracts based on their assessment of risk and in accordance with local authority requirements. Queries regarding applicability at specific sites should be directed to, and dealt with, by the client or principal contractor.
Version 5 of the CLOCS Standard was published in November 2024.
A summary of the changes in Version 5 of the CLOCS Standard can be accessed here and a copy of Version 4 of the Standard is available here.

Regulators/planning authorities must:
- Reference CLOCS in local plans and planning guidance and include compliance with CLOCS in the planning approval process.
- Ensure the planning process requires submission and approval of a Construction Logistics Plan.
- Obtain evidence that the CLOCS Standard is being upheld by requiring independent formal site monitoring assessments.
- Ensure breaches are identified and communicated to the regulator with steps taken to prevent future occurrences, and ensure all breaches are reviewed to ensure any risks to communities have been mitigated.
