Written questions by McMurdock.

What guidance her Department has issued to local authorities on preventing the recurrence of potholes in the same locations.

Local highway authorities have a duty under Section 41 of the Highways Act 1980 to maintain the public highway network in their area. The Act does not set out specific standards for maintenance, as it is for each individual local highway authority to assess which parts of its network need repair and what standards should be applied, based upon their local knowledge and circumstances. The Department does not gather information from local highway authorities about the causes or recurrence of individual potholes. There are occasions where potholes need to be repaired quickly for safety reasons, but the Department encourages local authorities to focus on long-term preventative maintenance, which is more cost-effective than the reactive patching of potholes. This is a core aspect of the Code of Practice for Well-managed highways infrastructure, which states that “when determining the balance between preventative and reactive maintenance, authorities should adopt the principle that prevention is better than cure”. This is available online, at: https://www.ciht.org.uk/ukrlg-home/code-of-practice/. The Government is also encouraging local highways authorities to take a long-term preventative approach by making some of their funding conditional on meeting certain best practiced criteria. To qualify for their full share of this financial year's £500m uplift in highways maintenance funding, local authorities had to publish transparency reports and set out how they comply with best practice, for example in relation to the extent to which they prioritise preventative maintenance. In this context, the Department for Transport wrote to all local highway authorities in England in December to inform them whether they would be receiving their full funding uplift, and emphasised the importance of following the guidance set out in the Code of Practice with regard to preventative maintenance. The findings from the transparency reports will enable the department to identify where extra support may be needed to ensure compliance with best practice. The department will set out more detail on the further support and training it will make available to local authorities in due course. Finally, regarding analysis of the effectiveness of preventative maintenance approaches, in November 2024 the Department for Transport published an Economic Appraisal of Investing in Local Highway maintenance. The analysis found that proactive maintenance can be more cost effective. In contrast, reactive maintenance was shown to be less cost-effective and associated with higher long-term expenditure.

What assessment she has made of the potential impact of the weight of electric vehicles on the condition of the local road network.

The Government recognises that heavier vehicles can accelerate road surface wear. While we have not undertaken a specific assessment of this effect, we are actively considering the implications of introducing zero-emission heavy goods vehicles, including the potential for additional road wear. The increasing weight of all road vehicles, both electric vehicles (EVs) and their petrol and diesel counterparts, is one of many factors affecting the condition of our roads. While EVs tend to be heavier than their equivalent petrol or diesel counterpart, on average all passenger cars have been increasing in weight for many years. This trend has been driven by consumer choice and improving safety features for passengers. It is the much heavier commercial vehicles, rather than passenger vehicles, that cause the most wear and tear to road surfaces and other highway structures. More broadly, there are many reasons why loadings on local roads may change, such as commercial development increasing traffic and the number of heavier vehicles on a road. Because of this, guidance for local authorities already highlights the need for maintenance plans to account for changes in circumstances. The main guidance for local highway authorities on asset management is the Code of Practice for Well-Managed Highways Infrastructure, published by the UK Roads Leadership Group and funded by the Department for Transport. The guidance sets out a national framework for how local highway authorities should manage their networks using a risk-based, evidence-led approach, taking account of current and expected highways usage.

What assessment she has made of the potential impact of the logistics industry to the achievement of the Modern Industrial Strategy.

Government recognises the logistics industry as a critical enabler of the Modern Industrial Strategy (IS) and its wider economic growth ambitions. The IS identifies freight and logistics as a cross-cutting sector, essential to the success of the Government’s growth ambitions across the eight frontier industries.Page 159 of the Strategy also recognises ports as a key foundational sector, providing critical inputs that enable growth across these frontier industries. This approach is supported by the National Wealth Fund, which will help unlock long-term private investment in strategically important infrastructure, including ports and associated logistics capacity, where this supports economic growth, industrial competitiveness and the transition to net zero.Logistics therefore plays a central role in strengthening national supply chain resilience and supporting delivery of the Industrial Strategy. This contribution will be further reflected in the forthcoming plan for freight, which will set out how Government will work with industry and investors to support long-term growth.

What assessment she has made of the overall condition of the local road network in England.

The Government takes the condition of local roads very seriously and is committed to maintaining and renewing the local highway network, which is why the Government has announced a record of £7.3 billion investment for local highway maintenance over the next four years, bringing annual funding to over £2 billion annually by 2029/30. This investment to improve the condition of our roads will make journeys faster and smoother but also protects drivers from paying hundreds of pounds in costly repairs following pothole-related breakdowns. This builds on nearly £1.6 billion in capital funding that has been provided for local highways maintenance in England for the financial year 2025/26, a £500 million increase compared to the previous financial year. Funding allocations for individual local authorities can be found on gov.uk. DfT collects and collates information on the condition of roads from local authorities in England annually. This information is published as official statistics. The latest release of these statistics was in December 2024, which covered data for the financial year ending March 2024. These statistics showed that in the financial year ending March 2024:Local ‘A’ roads: 4% should have been considered for maintenance, and 27% may require maintenance soon.‘B’ and ‘C’ roads: 7% should have been considered for maintenance, and 31% may require maintenance soon.Unclassified roads: 17% should have been considered for maintenance.The statistics can be found online, at: www.gov.uk/government/statistics/road-conditions-in-england-to-march-2024

What assessment her Department has made of the role of (a) drainage and (b) road foundations in the recurrence of potholes.

Local highway authorities have a duty under Section 41 of the Highways Act 1980 to maintain the highways network in their area. The Act does not set out specific standards of maintenance, as it is for each individual local highway authority to assess which parts of its network need repair and what standards should be applied, based upon their local knowledge and circumstances. Although the Government does not monitor the frequency of potholes caused by suspected drain related instances, it does encourage authorities to maintain their drainage assets through guidance. For example, the Pothole Guide (2019), commissioned by the Department for Transport and produced by the Association of Directors of Environment, Economy, Planning and Transport (ADEPT), set out that avoiding water penetration into the road surface is of paramount importance in preventing pothole formation, and that “keeping highway drainage systems working as effectively as possible is therefore a key area of maintenance activity.” Further guidance on asset management for local highways authorities can be found in the Code of Practice for Well-Managed Highways Infrastructure. This states that “drainage assets should be maintained in good working order to reduce the threat and scale of flooding. Particular attention should be paid to locations known to be prone to problems, so that drainage systems operate close to their designed efficiency.”

Whether her Department collects data on the proportion of reported potholes attributable to (a) standing water and (b) poor drainage.

What data she collects on (a) injuries and (b) fatalities linked to road surface defects.

The percentage and number of casualties (by severity) involved in reported road collisions in Great Britain where the “Poor or defective road surface or deposits on road” road safety factor was assigned for the last 10 years can be found in table RAS0701 published on gov.uk: https://www.gov.uk/government/statistical-data-sets/reported-road-accidents-vehicles-and-casualties-tables-for-great-britain#factors-contributing-to-collisions-and-casualties-ras07

What milestones remain before the full funding package for the Lower Thames Crossing is confirmed.

The Chancellor committed a further £891m to complete the publicly funded works for the Lower Thames Crossing, the final tranche of Government support to enable the private sector to take forward construction and long-term operation.There are a number of key activities to complete before the project is taken forward by investors, each with its own milestones. These activities include, for example, providing the project with the necessary legislative powers, enabling the appropriate regulation and devising and running a competitive process to attract investors whilst driving value for money for users. These will take place alongside the activities on the essential early works and utilities.

What plans she has to fund infrastructure to support the logistics industry.

This Government is taking signification action on infrastructure used by logistics. National support for the road haulage industry includes joint investment with industry in lorry parking and driver welfare facilities of up to £35.7 million. This is in addition to up to £30 million joint investment by National Highways and industry to improve lorry parking on the strategic road network (SRN). The Government is also investing £25 billion in the SRN over the next 5 years. At Autumn Budget 2025, the Government committed a further £891 million to complete the publicly funded works for the Lower Thames Crossing, to enable the private sector to take forward construction and long-term operation. The most significant road building scheme in a generation, this will relieve congestion at the Dartford Crossing, improve connectivity across the UK and to major ports, improving resilience and reliability for freight. To support decarbonisation, the Government has invested up to £120 million in the Zero Emission HGV and Infrastructure Demonstrator, alongside up to £30 million in the Depot Charging Scheme. The Plug‑in Truck Grant also helps reduce the upfront cost of zero‑emission HGVs. The recent Spending Review saw average annual funding increase for the Rail Network Enhancements Pipeline over the next four years which will support rail freight growth. My department is updating planning and regulatory processes for ports, including the National Policy Statement for Ports. The Government is working with the National Wealth Fund, which has committed at least £5.8 billion of its capital to five sectors, including ports.

What assessment she has made of the energy efficiency of electric heavy goods vehicles.

The Zero Emission HGV Infrastructure Demonstrator programme will report on the impacts of weather, terrain, driver behaviour, and payload on efficiency and range of electric HGVs. Over 150 vehicles are now operational in UK fleets with a further 150 due to enter service by March 2026. A trial of 20 electric HGVs in public sector fleets ran between April 2022 and September 2023 and information including total miles travelled, energy consumption, and vehicle range were published and are available online at http://bett.cenex.co.uk.

How many road traffic accidents involved road surface defects as a contributory factor in each of the past three years.

The number of reported personal injury road collisions in Great Britain that were assigned the “Poor or defective road surface or deposits on road” road safety factor (RSF) are shown in the table: YearCollisions20221,09220231,24820241,378 Data on road collisions involving personal injury are reported to the Department by police forces in Great Britain via the STATS19 system.Following the most recent STATS19 review contributory factors (CFs) are being replaced by new road safety factors (RSFs), in some police forces from late 2023 onwards. This has resulted in a break in the time series for some of the data. As a result, we are presenting all data using the RSF specification (direct), but separating out data initially recorded as CFs (converted). Because of that, the numbers presented are the combination of direct and converted numbers. Further details can be found in published road safety factors guidance. STATS19 includes all road collisions involving human death or personal injury occurring on the Highway ('road' in Scotland) and notified to the police within 30 days of occurrence, and in which one or more vehicles are involved, are to be reported. Collisions occurring on private roads (except Royal Parks) or in car parks are not included. Full details of which roads are reportable for STATS19 purposes can be found in the STATS20 guidance available here: https://www.gov.uk/guidance/road-accident-and-safety-statistics-guidance#data-collection

Whether changes will be made to the provision of road safety campaigns under the new media strategy arrangements.

THINK! is the Government’s flagship road safety campaign that aims to reduce the number of people killed and seriously injured on the roads in England and Wales.THINK! prioritises running campaigns to change attitudes and behaviours among those most at risk. There are currently no planned changes to the provision of road safety campaigns. These will continue to target priority issues such as drink driving, drug driving and speeding, as well as communicating other key policy interventions at the appropriate times.
