It is no longer enough for a council, local authority, contractor or insurer to say a road inspection happened; there is now the requirement to show what was inspected, by whom, when, where, what was found, what decision followed, and whether that response aligned with policy and timescales.
The conversation is shifting from activity to proof. Section 58 defences, “Well-Managed Highway Infrastructure”, the Department for Transport’s new transparency and ratings regime, and PAS 2161, all place greater emphasis on evidence, consistency and data quality.
In practical terms, defensible highway data is data that creates a clear, auditable decision trail. That includes:
- the inspection regime in place
- the location and severity of the issue
- who, or what system, captured it
- the rationale behind the risk decision
- the repair response
- and records retained in a format that can withstand scrutiny.
National guidance is increasingly clear: if a claim is made, authorities need accurate, time-stamped records that show not only what defects were found, but also when nothing actionable was identified and why the response taken was considered appropriate.
In simple terms, “we inspected it” is no longer enough. Authorities are now expected to prove inspections were carried out consistently, correctly and with a reliable audit trail behind them.

Why Evidence Matters
Pressure on highway authorities is nothing new but it is increasing, and at pace. The Asphalt Industry Alliance’s ALARM 2026 report found councils in England and Wales now face a record £18.62 billion carriageway repair backlog, while road-user compensation claims and associated staff time cost £31 million in 2025/26.
In this environment, it is no longer enough to simply carry out inspections. Loal authorities increasingly need to evidence them clearly, consistently and at scale. The conversation is shifting from collecting more data to collecting better data: accurate, auditable information that supports decisions, demonstrates compliance and stands up to scrutiny when required.
As expectations around transparency, compliance and accountability continue to rise, local authorities need the systems, processes and data practices in place to support this shift.
Why Is The Sector Shifting From Activity To Proof?
Highway authorities are facing growing operational, financial and political pressure. Despite maintenance budgets rising by 17%, road condition improvements remained limited, with…
“Almost one in 10 miles of local road likely to require maintenance within the next year.” (ALARM Survey, 2026)
The claims environment is also intensifying. RAC analysis found pothole compensation claims submitted to councils almost doubled between 2021 and 2024, while many rejected claims relied on Section 58 defences. At the same time, the Department for Transport’s transparency and ratings regime, alongside concerns raised by the National Audit Office around road condition data quality, are increasing expectations around evidence, accountability and best practice.
As a result, the focus is shifting towards higher-quality, more structured data that can support decisions, demonstrate consistency and withstand scrutiny when needed.
What Is Defensible Highway Data?
Defensible data creates a clear evidence trail linking inspections, decisions, actions and retained records. In practice, that is how Section 58 works: the defence depends not just on whether an inspection took place, but whether an authority can demonstrate it acted reasonably based on the level of risk at the time.
Well-Managed Highway Infrastructure reinforces the same principle, placing strong emphasis on accurate records, auditability, competence and quality assurance. Defensible road data is therefore more than defect capture alone; it is the ability to evidence the full decision making process behind it.

PAS 2161, The Move Towards Higher Quality Data, And Why it Matters
PAS 2161 is helping raise expectations around the consistency, quality and reliability of road condition data across the sector. While it is not a legal checklist for defending claims, it does place greater emphasis on validated, repeatable and quality assured road data capture.
This matters because stronger evidence depends on stronger road condition and monitoring data. Councils increasingly need information that is structured, auditable and reliable enough to support both operational decisions and long term accountability.
That is where AI-driven monitoring and repeatable survey methods are becoming increasingly valuable. Technologies such as Route Reports help authorities capture consistent, geolocated and time-stamped data at scale, strengthening the quality and traceability of the evidence available across the whole inspection and maintenance process.
Defensibility, however, still depends on the wider workflow around that data, including inspection policy, risk assessment, repair response and record retention.
Manual vs. Automated Inspections
The debate is no longer “manual versus automated.” The strongest inspection strategies increasingly combine both.
Manual inspections:
- Remain valuable for local context, close-up assessment and targeted follow-up work. But they can be difficult to scale consistently across large networks, particularly when resources are stretched.
Automated surveys:
- Bring advantages in coverage, repeatability and metadata capture. They can collect consistent, geolocated records across large parts of the network quickly, while supporting stronger audit trails and quality assurance processes.
The most effective approach is typically a hybrid one: automation supporting broad network visibility and evidence capture, with human expertise guiding decisions, prioritisation and interventions.
From Survey Data To Evidence Trail
One of the biggest weaknesses in many highway operations is not inspection itself, but disconnected workflows. A defect may be identified and repaired, yet the evidence trail between inspection, decision and action is incomplete. A stronger workflow links:
- Inspection or survey capture
- Validated records and imagery
- Risk assessment and decision making
- Work orders and repair response
- Completion evidence and retention
When those stages connect properly, authorities can move from fragmented records to a clear, defensible audit trail.
The Bigger Opportunity
Insurers, auditors and courts are no longer focused solely on whether an inspection took place. Increasingly, they want to understand whether authorities can evidence the decisions made afterwards. That includes:
- whether inspections followed policy
- whether records were accurate and time-stamped
- whether non-repair decisions were justified
- whether repairs were completed within target times
- and whether the people or systems involved were competent and quality controlled.
-
But this shift is about more than claims defence. Higher quality highway data also supports better asset management, stronger prioritisation and more informed investment decisions.
As PAS 2161 adoption, transparency requirements and public scrutiny continue to increase, the challenge for local authorities is no longer simply collecting data. It is ensuring that data is consistent, connected, auditable and usable across the full lifecycle of inspection, maintenance and reporting.
This is exactly why many authorities are now exploring more structured, AI-driven approaches to road monitoring, helping create stronger evidence trails, better network visibility and more informed decision-making across the highway lifecycle.
