A petition calling for Blood Bikers to use flashing green lights has prompted a debate about visibility, rider safety and the meaning of emergency warning lights. The intention is understandable: protect the volunteers who support our health service. But would this change make their journeys safer?

The volunteers behind the deliveries

Blood Bike charities provide a vital service, transporting blood, samples, donor milk and other medical supplies between healthcare organisations. Their unpaid volunteers help the NHS get essential items where they are needed, free of charge.

Much of that work happens out of hours, including nights, weekends and bank holidays. These are riders giving up their own time to support patient care, often in difficult weather and road conditions.

Their safety deserves serious attention. The question is whether green lights are the best way to improve it.

What green lights actually mean

In Great Britain, the Road Vehicles Lighting Regulations restrict the use of a green warning beacon to a vehicle occupied by a General Medical Council registered medical practitioner and being used for the purposes of an emergency.

A green light is a warning signal. It does not, by itself, give the driver permission to speed, pass through red lights or assume that other road users will give way.

The Highway Code advises road users to make space for approaching emergency vehicles when it is safe to do so, while continuing to comply with traffic signs. Making way must never mean putting yourself or somebody else in danger.

That distinction matters here: allowing Blood Bikers to display green lights would not automatically give them exemptions from the usual rules of the road.

Could green lights improve rider safety?

Supporters hope flashing green lights would make Blood Bikers more noticeable and encourage drivers to give them space. For volunteers travelling at night or in poor weather, that is an understandable concern.

However, greater visibility and greater safety are not necessarily the same thing. Any change would need evidence that it helps drivers recognise and respond safely to a Blood Bike.

There is also a question about expectations. Would a driver interpret the light as a request for extra care, or assume that the rider was responding to an emergency and expecting priority?

Confusion could affect both the rider and the people around them. Training, insurance and clear public guidance would all need consideration before a change was introduced.

Listening to the Blood Bike community

The Nationwide Association of Blood Bikes (NABB) represents member groups across the UK and Ireland. Its views deserve weight, alongside those of individual charities and volunteers, whose opinions may differ.

In the statement quoted when this debate arose, NABB opposed the petition and asked the public to support its volunteers through greater awareness and consideration:

“Give us the courtesy of the road and make it as safe for us as you can!”

One Blood Biker we know expressed their own view just as plainly:

“Us Blood Bikers neither need nor want green flashing lights.”

Those views should not be taken as speaking for every volunteer. They do, however, show why a well-intentioned proposal needs the involvement of the people it is intended to help.

Our view: protect the riders first

Blood Bikers deserve recognition, practical support and safer roads. We remain cautious about extending the use of green lights without clear evidence of a safety benefit and a shared understanding of what the lights would mean.

Any proposal should be developed with Blood Bike charities, riders and the relevant authorities. It should address training and driver behaviour as well as the equipment fitted to a motorcycle.

Meanwhile, every driver can help: check carefully at junctions, watch for motorcycles in mirrors and blind spots, and give riders the time and space to travel safely.

These volunteers are doing something important. Looking out for them should be part of how we drive every day.
