The Environment Protection Act 1990 governs the responsibility for clearing highway litter and sweeping carriageways. National Highways is responsible for litter collection on motorways and some ‘A’ roads while the relevant Local Authority manages litter collection on the rest of the roads in England.

National Highways undertakes weekly safety inspections on the M60 and M67. National Highways’ most recent inspection of the M67 and M60 in Denton took place on 20 March 2025. The performance of contractors and their completion of maintenance activities are reviewed and monitored monthly by National Highways.

National Highways’ Performance Specification includes a Performance Indicator for litter. This metric monitors the cleanliness of the Strategic Road Network and is the percentage of the Strategic Road Network where litter is graded at A or B as defined in the Department for Environment, Food and Rural Affairs’ Code of practice on Litter and Refuse. National Highways performance indicator score for 2023-24 is 59.2% of the Network is graded at A or B.

National Highways is monitored against its Performance Specification by the Office of Rail and Road (ORR). The ORR report annually to Parliament and the public on National Highways’ performance, including litter. If the ORR deem that National Highways is not complying with its statutory directions or complying with the requirements of the Road Investment Strategy, they may determine enforcement action to be appropriate.

National Highways is monitored against a litter performance indicator as part of the Road Investment Strategy (RIS2). This requires them to report on the percentage of the Strategic Road Network (SRN) where litter is graded at B or above under the Department for Environment, Food and Rural Affairs' Litter Code of Practice. National Highways performance on this metric is reported to the Office for Road and Rail and published annually.

National Highways consider litter to be a very serious problem. It is harmful to the environment, damaging to their reputation, and upsets their customers. It also creates a risk to the substantial number of people who collect it, and uses resources that could instead be better used to improve the road network.

A trunk road is classified as special if are restrictions on the types of vehicles which can use them, for example a Motorway. The Government has no plans to alter this definition.

Under Section 86 of the Environmental Protection Act (1990) any transfer of litter clearance responsibility would need to be requested by National Highways after consultations with relevant Local Authorities. It is important to take a proportionate, evidence-based approach which recognises the pressures on Local Authority resources and costs associated with roadside litter clearance. The Government expects National Highways to work collaboratively with Local Authorities to solve local issues and keep roadsides clear of litter and refuse as far as is practicable.

The Department recognises the importance of addressing the issue of litter on trunk roads, as per the responsibilities laid out in Section 89 of the Environmental Protection Act 1990. We work closely with local authorities to resolve local issues as far as is practicable and support them in fulfilling their obligations under the law. This includes regular inspections and audits, as well as feedback from the public and other stakeholders. If any issues are identified, we work with the local authorities to address them, which may involve providing additional resources or training.

The Department takes the issue of litter on trunk roads very seriously. We are committed to working with local authorities to keep our roads free of litter and refuse, creating a cleaner and safer environment for all. Together, we can make significant progress in addressing this issue and creating a better future for our communities.

The second Road Investment Strategy (2020-25) includes a litter performance indicator. National Highways is committed to reporting the percentage of the Strategic Road Network on which National Highways hold litter clearance responsibility, that had no litter, refuse or detritus, or was predominately free of litter, refuse or detritus apart from some small items in line with the Code of practice on litter and refuse published by Department for Environment, Food and Rural Affairs (DEFRA). The Department, alongside the independent Highways Monitor (Office for Rail and Road) regularly monitor performance against this litter indicator and discuss with National Highways how performance can continuously be improved.

We are developing the third Road Investment Strategy (RIS3) and continue to explore potential metrics for inclusion in RIS3 performance specification, as well as possible improvements to existing metrics such as litter. We are working to ensure that the targeted metrics in RIS3 – the Key Performance Indicators focus on the things that are most important to road users and contribute to wider government priorities. This process will involve considering the responses to the forthcoming public consultation on National Highways’ Strategic Road Network Initial Report.
