Highway Safety Audits: What They Are and Why They Matter in Pakistan

Every year, thousands of lives are lost on Pakistani roads. According to the National Highway and Motorway Police (NHMP), road accidents claim over 25,000 lives annually in Pakistan, with many more left injured or permanently disabled. Behind most of these tragedies lies a common thread: roads that were not designed, reviewed, or maintained with safety as the top priority — a problem we explored in detail in our piece on the importance of road safety equipment in preventing accidents.

This is exactly where the highway safety audit process comes in. A structured, step-by-step review of road design and conditions, highway safety audits have helped countries across the world cut road fatalities dramatically. Pakistan, with its expanding motorway network and growing CPEC-related infrastructure, stands at a crossroads — the right investment in safety auditing today can save countless lives tomorrow.

What Is a Highway Safety Audit?

A highway safety audit (HSA) is a formal, independent examination of a road project or existing road to identify safety problems and recommend corrective measures. It is not about fault-finding or blame. It is a proactive tool that evaluates whether a road is as safe as it can be for all users: drivers, motorcyclists, cyclists, and pedestrians.

The audit is carried out by a trained team of road safety experts who physically inspect the road, review design documents, and assess conditions at different times of day. Their findings are documented in a formal report with clear recommendations for improvement.

The concept was first developed in the United Kingdom in the late 1980s and has since been adopted worldwide, including by the Asian Development Bank (ADB) and World Bank for projects in developing countries like Pakistan.

Types of Highway Safety Audits

Not all safety audits are the same. The type of audit performed depends on the stage of the road project or the condition of the existing network.

• Stage 1 – Feasibility and Preliminary Design Audit: conducted at the planning stage before construction begins. The team reviews route alignment, intersections, and design concepts to catch safety issues early, when changes are cheapest to make — the same early-stage thinking we cover in how highway expansion projects are planned and executed.
• Stage 2 – Detailed Design Audit: reviews the complete engineering drawings and technical specifications, checking lane widths, sight distances, road markings, signage, and drainage plans.
• Stage 3 – Pre-Opening Audit: carried out just before a new road is opened to traffic. The team physically walks and drives the road to spot anything that may have been missed in design — sharp edges, missing guardrails, confusing signs, or blind spots.
• Stage 4 – Operational Audit (In-Service Audit): performed on roads already open and in use, using accident data, site observations, and driver behaviour studies to identify problem locations and recommend targeted fixes.

In Pakistan, Stage 4 operational audits are particularly valuable given the existing condition of many national and provincial highways, and they increasingly intersect with the kind of smart-infrastructure thinking covered in our roundup of top highway construction trends.

The Highway Safety Audit Process Explained Step by Step

Understanding the highway safety audit process clearly is important for engineers, road planners, government officials, and even the general public. Here is how the process works from start to finish.

Step 1: Forming the Audit Team

Every highway safety audit begins with assembling the right team. A typical HSA team includes a road safety engineer, a traffic engineer, and sometimes a human factors specialist or a local road authority representative. The team must be independent — meaning they were not involved in designing the road being audited. Independence is crucial; when the people who designed a road also evaluate it, blind spots are inevitable. An outside team brings a fresh perspective.

Step 2: Collecting Background Information

Before the site visit, the audit team collects all available data: road design drawings and specifications, accident records, traffic volume counts, speed data, and any previous maintenance or safety reports. Pavement condition history is part of this picture too — our guide on pavement life cycle cost analysis explains how that data is gathered and used to plan maintenance and prioritise risk.

In Pakistan, this data is often held by the National Highway Authority (NHA), provincial highway departments, or the NHMP. Accessing complete and accurate records can sometimes be a challenge, which is itself a systemic issue worth addressing.

Step 3: The Site Visit

This is the most hands-on part of the process. The audit team visits the road during both daylight and night-time conditions, and sometimes during rain or fog to assess visibility and surface conditions. During the visit, the team looks for a wide range of safety concerns:

• Poor horizontal or vertical alignment, and unsafe intersections or merging points — the issues our guide on how modern road design improves traffic flow is built around.
• Inadequate road markings and signage. This is one of the most common findings on Pakistani roads; see our breakdowns of critical road marking mistakes and our complete guide to paint for road marking for what compliant markings should look like.
• Missing or damaged guardrails and barriers, covered in depth in our piece on roller barrier guard rail systems.
• Poor drainage leading to flooding or slippery surfaces — a risk that’s intensifying, as we discuss in the impact of climate change on road infrastructure design.
• Pedestrian crossings that are unclear or dangerous, and roadside hazards like utility poles, trees, or unprotected embankments.

On Pakistan’s highways, common problems include unmarked speed bumps, missing kilometre markers, inadequate lighting near toll plazas, and poorly designed U-turns on expressways like the M-2 and M-9. Many of these gaps trace back to the same nighttime-visibility issues we cover in why reflective road signs are critical for nighttime driver safety.

Step 4: Identifying and Documenting Safety Issues

After the site visit, the team prepares a detailed list of every safety problem observed. Each issue is described clearly, along with its location, potential severity, and likely cause. Good audit documentation uses photographs, sketches, and GPS coordinates so that road authorities can quickly identify and act on the findings. Vague descriptions without location references are one of the most common shortcomings in poorly conducted audits.

Step 5: Developing Recommendations

For every safety issue identified, the audit team proposes a practical recommendation, usually categorised by urgency: immediate action required, short-term improvement needed, or long-term design change recommended. Recommendations must be realistic and cost-effective — in the context of Pakistan’s budget constraints, a recommendation to add retroreflective road markings or visibility aids like cateyes and road studs at dangerous rural bends is far more likely to be implemented than a proposal to completely reconstruct an intersection. Other common low-cost, high-impact fixes include convex mirrors at blind curves, delineator posts along unprotected embankments, anti-glare shields on undivided carriageways, and properly marked speed breakers at school zones and built-up areas.

Step 6: Preparing the Formal Audit Report

The findings and recommendations are compiled into a formal audit report, submitted to the road authority or project owner, who is then required to respond formally — either confirming they will implement the recommendation, explaining why it is not feasible, or proposing an alternative solution. This formal response requirement is what gives the audit process its teeth. Without it, reports risk being filed away and forgotten.

Step 7: Monitoring and Follow-Up

A safety audit is not complete when the report is submitted. A follow-up process is needed to check whether recommendations have actually been implemented and whether they achieved the desired safety improvement. Some countries build this follow-up into formal project requirements, tied to funding or regulatory compliance. In Pakistan, the ADB and World Bank have begun including HSA requirements as a condition of infrastructure financing, which is encouraging progress.
