THE UK IS FALLING BEHIND: WHAT OTHER COUNTRIES ALREADY UNDERSTAND ABOUT BUS DRIVER HEAT SAFETY

Over the last few weeks I have received message after message from bus drivers across the UK describing cab temperatures exceeding 40°C, steering wheels too hot to touch, dashboards radiating heat and drivers feeling physically sick behind the wheel.

Some buses are reportedly already sitting at 25°C before even leaving the depot in the morning.

This is no longer a debate about “comfort”.

It is a professional driver safety issue.

And increasingly, it is becoming clear that the UK is falling behind other countries which already recognise heat exposure and cab temperature as operational safety risks requiring proper protections, standards and procedures.

The worrying part is that proven examples already exist around the world.

The UK does not need to invent solutions from scratch.

The industry simply needs the political will and leadership to act.

GERMANY – HEAT IS TREATED AS A SAFETY ISSUE

Germany has one of the strongest workplace safety cultures in Europe.

In many German operations:

• buses are fitted with sealed driver cabs and dedicated climate control systems;

• defective cooling systems are treated seriously;

• employers are expected to formally assess heat risk;

• working conditions are viewed through the lens of concentration, fatigue and human performance.

There is a far greater acceptance that excessive heat affects:

• reaction times;

• concentration;

• fatigue;

• alertness;

• and ultimately road safety.

That mindset is significantly ahead of much of the UK industry where drivers are still often expected to simply “open a window and get on with it”.

FRANCE – FORMAL HEAT RISK EXPECTATIONS

France has increasingly strengthened workplace protections around extreme temperatures and heatwaves.

Employers are expected to:

• assess heat-related risks;

• provide hydration and cooling measures;

• adapt work arrangements during severe heat;

• take reasonable steps to protect workers during national heat alerts.

French cities have also invested heavily in modern air-conditioned fleets.

Importantly, the issue is increasingly viewed as occupational health protection rather than a personal inconvenience.

SPAIN – OPERATING IN EXTREME HEAT

Spain regularly experiences temperatures far beyond what the UK traditionally faced.

As a result, many Spanish operators already regard functioning air-conditioning as essential infrastructure rather than a luxury.

In parts of Spain:

• buses without working cooling systems can face operational restrictions;

• climate-controlled driver areas are common;

• heat management procedures are more established.

The UK is now experiencing more frequent extreme heat events — yet many operators still behave as though these temperatures are exceptional rather than becoming part of a new normal.

AUSTRALIA – DRIVER FATIGUE AND HEAT AWARENESS

Australian transport systems increasingly recognise the relationship between:

• heat;

• dehydration;

• fatigue;

• and driver performance.

Modern fleets often incorporate:

• advanced HVAC systems;

• UV-reducing glass;

• stricter defect reporting for failed cooling systems.

In Australia, there is wider recognition that extreme heat directly impacts safety-critical decision making.

That should not be controversial.

Professional drivers are expected to maintain constant concentration for hours in busy traffic conditions carrying passengers and interacting with vulnerable road users.

UNITED ARAB EMIRATES – EXTREME CONDITIONS REQUIRE EXTREME PRECAUTIONS

Despite major differences in wider labour systems, the UAE has long recognised the dangers of prolonged heat exposure.

In some sectors there are:

• mandatory cooling requirements;

• heat protocols;

• restrictions during peak temperatures.

Frankly, it should embarrass parts of the UK bus industry that drivers here are still sitting in cabs exceeding 40°C with little meaningful protection.

SCANDINAVIA – DRIVER WELFARE BUILT INTO DESIGN

Countries such as Sweden and Norway often approach public transport with stronger welfare principles from the outset.

Modern vehicles frequently include:

• climate-controlled driver environments;

• ergonomic cab design;

• stronger recognition of fatigue and welfare risks;

• better overall operational standards.

The philosophy is simple:

protecting the driver protects the public.

That is a principle the UK increasingly needs to rediscover.

LONDON MAY HAVE JUST SHIFTED THE DEBATE

What makes the recent comments from Transport for London and TfL Director of Buses Lorna Murphy so significant is that London may have effectively acknowledged the principle already.

TfL stated:

“If air cooling systems on a vehicle are not functioning and drivers do not feel they can carry out their duties safely, they should contact the controller and action will be taken to support them.”

TfL also stated operators should never take action against workers raising welfare concerns.

Separately, Andy Lord confirmed publicly that buses with defective cab cooling should not enter service.

That matters.

Because for years drivers across the UK have often felt pressured into simply carrying on regardless.

TfL’s comments now raise serious questions for the wider industry:

• If London accepts defective cab cooling can make buses unsafe, why are other operators still treating this as optional?

• If London acknowledges welfare as part of operational safety, why is there still no national framework?

• If London recognises the risks, why are many drivers elsewhere still left without meaningful protections?

THE UK’S BIGGEST FAILURE – NO NATIONAL STANDARD

At present the UK has:

• no maximum legal cab temperature for buses;

• no dedicated national bus driver heat safety framework;

• no DVSA standard specifically covering excessive cab temperatures;

• no Traffic Commissioner guidance focused on heat stress;

• no nationally enforceable cooling standards for bus driver environments.

So drivers are often left relying on:

• general HSE legislation;

• Section 44 protections;

• employer discretion;

• or union pressure.

That is not a coherent safety system.

Especially when temperatures are continuing to rise year after year.

LOCAL LEADERS MAY NOW NEED TO STEP IN

If Westminster continues failing to act, pressure increasingly needs to move towards local transport leaders and combined authorities.

Mayors and transport authorities now have an opportunity to show leadership.

That includes:

• Andy Burnham – Bee Network;

• Tracy Brabin – Weaver Network;

• Oliver Coppard – South Yorkshire;

• Steve Rotheram – Liverpool City Region;

• Claire Ward – EMCCA;

• and other local transport authorities across the country.

TfL has now publicly recognised the issue.

Others should do the same.

Because if legislation is not coming nationally, local transport leaders may need to set expectations themselves through:

• franchising standards;

• enhanced partnerships;

• operator contracts;

• procurement conditions;

• and public safety policies.

THIS IS ABOUT PUBLIC SAFETY

Bus drivers are expected to:

• maintain concentration for long hours;

• safely carry passengers;

• navigate congestion;

• monitor vulnerable road users;

• operate large vehicles in complex urban environments.

Yet some are doing so in temperatures exceeding 40°C.

That should concern everybody.

The industry cannot continue pretending this is simply about comfort.

Because eventually one of two things will happen:

• either the industry acts now;

or

• a serious incident happens and everyone suddenly pretends the warnings were never there.

The evidence, warnings and driver testimonies are already here.

The question now is whether the UK chooses to listen.
