Can I claim if I was injured cycling without a bike helmet?

If you were injured cycling without a helmet, a claim is possible. However, the defendant may argue that not wearing a helmet amounts to 'contributory negligence'. What does this mean?

How much protection does a cycling helmet provide?

Cycle helmets are designed to withstand an impact equivalent to an average weight rider travelling at a speed of 12 mph falling onto a stationary kerb shaped object from a height of 1 metre.

Most cycling accidents occur within these parameters and it might, therefore, be concluded that helmets offer protection most of the time.

It is generally agreed that wearing a helmet is far safer than not wearing a helmet. Critically this is the view taken by most courts.

What about the studies that dispute the efficacy of cycling helmets?

There have been a number of academic studies on the safety of cycling helmets.

Research conducted by Dr Ian Walker, a traffic psychologist from the University of Bath revealed that, bizarrely, drivers gave helmet-wearing cyclists less room when overtaking; forcing them to deal with potholes and drain covers, potentially increasing the likelihood of accident and injury.

His findings also suggested that helmets although useful in low speed falls or tumbles over the handlebars, may not offer much protection in the event of a collision with a motor vehicle.

Another study from the Transport Research Laboratory 'the potential for cycle helmets to prevent injury' supports this view.

Bicycle helmets are made from polystyrene and are designed to protect wearers from falls to the ground at under 12mph. Some research even suggests there is a risk of rotational brain injury and neck injuries through helmet air vents catching on the road surface.

What does the law say about wearing a helmet on a bike?

Under UK law, it is not compulsory for cyclists to wear helmets. However, the Highway Code rule 59 does recommend that you:

"wear a cycle helmet which conforms to current regulations, is the correct size and securely fastened".

You are not, therefore, committing a criminal offence if you cycle without a helmet.


Section 38 of the Road Traffic Act 1988 says:

“A failure on the part of a person to observe a provision of the Highway Code shall not of itself render that person liable to criminal proceedings of any kind but any such failure may… be relied upon by any party to the proceedings as tending to establish or negative any liability which is in question in those proceedings.”

In other words, you could be found liable (or partly liable) for your own injuries - even if the other party was apparently to blame.

Can I still get compensation if I wasn't wearing a helmet?

Yes. If you were injured on your bike and someone else was to blame, we can help you claim cycling injury compensation. If you were not wearing a helmet and you suffered head injuries, the defendant may argue that you contributed to the severity of your own injuries. This defence is known as 'contributory negligence'. Even if this defence is upheld, you should still receive some compensation, albeit a reduced amount.

How does contributory negligence work?

If you were not wearing a helmet and you suffered head injuries, the defendant will probably argue that your injuries would have been less severe if you're wearing a helmet.

The courts will usually agree with this reasoning especially if the medical evidence supports it.

(Insurance companies routinely adopt the default position of contributory negligence when informed that you were not wearing a helmet - even if you didn't suffer head injuries!)

As most claims don't go to court, this legal argument is more like a negotiation between two parties, neither of whom really want to go to court.

More often than not, solicitors will be able to bat away the insurance company's initial position. However, if the medical evidence shows that your injuries would probably have been less severe if you were wearing a helmet, your compensation will be reduced accordingly.

For example:

If the medical opinion is that your head injuries would have been 50% less severe if wearing a helmet, your compensation award will probably be reduced to 50% of the amount it would otherwise have been.
