HGV movements in urban areas are often constrained during night-time and/or weekend periods by local regulations which have been put in place to minimise noise impacts. If such night-time delivery restrictions could either be relaxed or removed where appropriate, there are significant potential benefits, primarily from reduced congestion.

TRL has been commissioned by the Department for Transport (DfT) to consider the need for and the feasibility of a permissive low-noise certification scheme for HGVs and their operation, with options for scheme operation. It is envisaged that a relaxation of delivery restrictions could be granted by a local authority for a certain operator using ‘quiet HGVs’ that met the requirements of such a scheme.


This report reviews existing restrictions on night-time goods deliveries, implemented schemes or research projects addressing the issue, the needs (if any) for a permissive certification scheme based upon consultations with relevant stakeholders, barriers to the future introduction of such a scheme as well as the likely benefits and likelihood of successes.

The roles of stakeholders and scheme managers and the issues related to the enforcement of such a scheme are also discussed.

Key Findings:

  • Provisional recommendations are set out for a scheme addressing vehicle, body and ancillary noise associated with both the transport of goods between the point of origin and final destination, and the actual collections/deliveries themselves.
