Bus Driver Fatigue: If the Evidence Already Exists, Why Are We Still Studying It?

A recent exchange between London bus safety campaigner Kevin Mustafa and Transport for London raises an important and uncomfortable question for the bus industry: if the risks associated with bus driver fatigue are already well understood, why does the sector still appear to treat the issue primarily as something that requires further study rather than meaningful reform?

The issue itself is not new.

The issue of bus driver fatigue and distraction was highlighted in the London Assembly Transport Committee’s bus safety investigation, commonly referred to as Driven to Distraction, published in July 2017.

Following that investigation, Transport for London later commissioned further research, including work carried out by Loughborough University examining driver fatigue and working patterns on the London bus network.

Independent academic research has reinforced those concerns. Studies undertaken by Loughborough University examined the working patterns and operational pressures experienced by London bus drivers, highlighting how long duties, irregular shift patterns and insufficient recovery time can increase fatigue levels.

The evidence base therefore exists.

Yet the response from Transport for London continues to suggest that it is still “building the evidence base” around driver fatigue and the impact of scheduling.

This raises an obvious question: if the evidence has been available for years, what exactly is still being studied?

Fatigue Is Not a Welfare Issue. It Is a Safety Issue.

Bus drivers operate large public service vehicles in complex and often congested environments. In London alone, millions of passengers rely on the bus network every day.

Fatigue is therefore not simply a matter of driver comfort or workplace wellbeing.

Fatigue directly affects reaction times, concentration, decision-making and situational awareness. When drivers operate vehicles for extended periods under demanding conditions, fatigue becomes a safety risk not only for drivers themselves but also for passengers, pedestrians and other road users.

Other transport sectors recognise this reality.

In aviation and rail, fatigue is treated as a core safety issue supported by structured fatigue risk management systems and strong regulatory oversight. These sectors recognise that the human element of transport operations is critical to safety.

Yet within the bus industry fatigue is often still framed primarily as an employment issue rather than a system-level safety risk.

Who Is Responsible?

Transport for London’s response to concerns raised by campaigners notes that duty scheduling arrangements are agreed between operators and local trade unions.

Operationally, that is correct.

However, London’s bus services operate under contracts let by Transport for London. The authority sets the framework within which operators deliver services.

This means that while operators manage day-to-day staffing arrangements, Transport for London still has significant influence over the standards embedded within those contracts.

Driver welfare conditions, rest periods, welfare facilities and fatigue risk management are therefore not purely matters for individual operators. They are part of the wider system within which the network operates.

This is an important distinction.

If fatigue risks are known and documented, and if the contracting authority sets the operational framework of the network, then addressing those risks cannot be left solely to operators.

A System Question for the Bus Industry

The debate in London therefore highlights a wider issue facing the bus sector across Britain.

Driver fatigue, workplace violence, operational pressure and welfare facilities are often discussed as individual workplace concerns. In reality they are part of the broader safety environment within which bus networks operate.

As more regions move towards franchised or authority-controlled bus networks, this governance question becomes increasingly important.

Should driver welfare protections be embedded directly within operating contracts?

Should minimum standards for rest periods, welfare facilities and fatigue risk assessment be required across entire networks?

And should fatigue management be treated as a formal safety issue rather than simply an operational matter?

These questions are not theoretical.

Bus drivers operate at the frontline of the country’s most widely used form of public transport. The safety of millions of daily passengers ultimately depends on the people behind the wheel.

If the evidence regarding fatigue already exists, the real question is no longer whether the problem is understood.

The question is whether the industry is prepared to act on it.
