Common Causes of Motorcycle Accidents and How They Affect Personal Injury Claims
Motorcyclists face significantly higher risks on the road compared to other motorists. With little physical protection and a smaller road presence, it takes only a moment of inattention or negligence from another road user to cause a serious accident.

Understanding the most common causes of motorcycle accidents can help injured riders recognise whether they may have a legal claim for compensation and what evidence is needed to prove it.
Motorbike Accident due to a Driver Failing to Look Properly
One of the most common causes of motorbike accidents is other road users simply failing to see motorcyclists. This often happens when:
- a driver pulls out of a junction without checking mirrors
- a vehicle turns right across the rider’s path
- a driver misjudges the speed or distance of an approaching motorcycle
Because motorbikes are smaller and less visible, these collisions frequently lead to severe injuries.
Impact on claims:
If a driver failed to look or misjudged the rider’s position, liability usually rests with the driver. Evidence such as CCTV, dashcam footage, witness statements, or accident reconstruction can be crucial.
Motorcycle Accident due to a Driver Changing Lanes Unsafely
Many collisions occur when a motorist changes lanes without properly checking blind spots. Motorcycles can easily be hidden from view, particularly on busy dual carriageways or motorways.
Impact on claims:
Liability often depends on whether the motorist checked mirrors and signalled appropriately which can be difficult to evidence. For the rider, a helmet-mounted or bike-mounted camera can be extremely helpful as can dash-cam footage from other road users who may come forward as witnesses.
Motorbike Injury due to a Head-On Collision
Head-on collisions are among the most serious types of motorcycle accidents. They typically occur when a vehicle strays into the opposite lane, attempts to overtake without adequate visibility, or loses control on a bend.
Impact on claims:
These cases often lead to serious or catastrophic injuries. Liability is usually clear if the driver entered the rider’s lane, but police reports and expert evidence can strengthen the claim.
Motorcycle Injury due to Poor Road Conditions
Road defects cause a significant number of motorbike accidents. Compared to cars, motorbikes are much more vulnerable to:
- potholes
- uneven surfaces
- loose gravel or debris
- oil or diesel spills
- defective road markings
A hazard that a car may barely notice can cause a motorcyclist to lose control.
Impact on claims:
Claims involving road defects may be brought against the local authority or highway authority responsible for maintenance. Success depends on proving:
- the defect was dangerous
- the authority failed to inspect or repair it within reasonable timescales
Photographs and measurements of the defect should be taken as soon as possible.
Motorbike Accident due to Speeding and Reckless Driving
Motorbike accidents frequently involve excessive speed either by drivers or riders. High speeds reduce reaction time and significantly increase the severity of injuries.
Impact on claims:
If the other motorist was speeding or driving aggressively, liability is typically strong. However, if the rider was also speeding, contributory negligence may be raised. This does not defeat the claim but may reduce compensation.
Motorcycle Accident due to a Driver Being Distracted
The rise of mobile phone use has led to more accidents caused by driver distraction. Even checking a notification can cause a momentary lapse in concentration, enough to miss a motorbike filtering through traffic or approaching a junction.
Impact on claims:
Phone records, witness statements, and dashcam footage can all help prove distraction.
Motorbike Injury due to Alcohol or Drug Impairment
Impaired driving drastically affects judgment, coordination, and reaction time. Motorcyclists are often the victims of drivers who get behind the wheel under the influence.
Impact on claims:
Police evidence is key. Where impairment contributed to the accident, liability is usually straightforward.
Motorcycle Injury due to Mechanical Failures
Defective brakes, tyre blowouts, or mechanical faults can cause accidents. If maintenance was poor or a newly fitted part failed, liability may fall on:
- a garage
- a manufacturer
- another road user whose vehicle shed debris or fluid
Impact on claims:
Expert analysis of the motorcycle or the other vehicle may be needed to identify the cause of the incident.
How is Motorbike Injury Compensation Calculated in the UK?
Motorbike accident injury compensation in the UK depends on the severity of the injury, financial losses and strong medical evidence. This article explains how claims are valued, how the Judicial College Guidelines work, and which factors influence pay-outs. Learn how our specialist motorcycle injury compensation lawyers can help you recover the full compensation you deserve.
Proving Liability in a Motorbike Injury Claim: What Evidence Helps?
Regardless of the cause, evidence is crucial. Useful forms include:
- Accident scene photographs
- Helmet or bike-mounted camera footage
- Witness statements
- Police reports
- Medical records
- Engineering or road surface expert reports
Our specialist motorcycle injury lawyers can take responsibility for gathering this evidence and presenting it clearly to insurers or the court.
Contributory Negligence: When the Rider Is Partly at Fault
Even if a motorcyclist was partly responsible, for example, if they were speeding slightly or filtering through traffic, they may still have a valid claim. In such cases, compensation may be reduced by a percentage that reflects their contribution to the accident.

If you have been injured as a result of a motorbike accident then you may be eligible for compensation. Our experienced personal injury solicitors are here to support you through this difficult process, helping you secure the compensation and rehabilitation you are entitled to.
Conclusion
Understanding how motorcycle accidents typically occur can help injured riders recognise when negligence may have played a part. Whether caused by driver error, road defects, poor visibility, or dangerous behaviour, motorcyclists are entitled to pursue compensation when someone else was at fault.

Motorcycle Injury Compensation Claim FAQs
Motorcycle accidents are most often caused by driver error, such as failing to check mirrors or misjudging a motorbike’s speed, unsafe lane changes, and turning across a rider’s path. Other factors include poor road conditions, speeding, distracted driving, impaired driving, and mechanical failures.
Yes. If a collision occurs due to potholes, debris, oil spills, or defective road surfaces, the responsible local or highway authority may be liable. Successful claims require evidence that the defect existed and that the authority failed to address it within a reasonable timeframe.
Liability determines who is responsible for the accident. If another driver, a manufacturer, or a local authority is at fault, they (or their insurer) may be required to pay compensation. Evidence like police reports, CCTV, dashcam footage, or witness statements is crucial to proving liability.
If you contributed to the accident, your compensation may be reduced under contributory negligence. The reduction reflects your share of responsibility. For example, if you were speeding slightly, your payout might be decreased proportionally. Even so, you can still claim for the portion of the accident caused by the other party.
A specialist solicitor can investigate the cause of the accident, gather evidence, liaise with insurers, and establish liability. They can also ensure all losses including medical costs, lost earnings, and rehabilitation are properly included, helping you maximise your compensation.
