Motorcyclists are advised to choose crash helmets with care. A quality protective helmet can effectively reduce the risk of head injury in case of accidents.
According to statistics from the Transport Department, more than 2,500 motorcycles were involved in traffic accidents every year from 1999 to 2009. The accident involvement rate of motorcycles was more than 3 times higher than that of private cars.
A safety test on 17 motorcycle crash helmets was recently conducted by the Euroconsumers. 5 out of the samples available in Hong Kong are open-face helmets priced between HK$1,160 and HK$3,480.
Test results revealed that one model (among the 5 available locally) was found to be unsatisfactory in shock absorption performance, and 3 models were found to have a higher possibility of exposing part of the user's head in accidents.
Shock absorption is the main function of protective helmets. With reference to the Economic Commission for Europe Regulation No. 22 (ECE R22), the shock absorption performance was assessed by measuring the acceleration imparted to the headform fitted with the helmet. The lower the acceleration measured, the better the shock absorption.
The performance of one model was found unsatisfactory when dropped on flat steel anvil at the helmet's upper area. Retests were conducted on 2 more samples of this model, but results of one sample were still not satisfactory.
Other test items included retention system test, visor test and assessments on practical use.
In the test on the helmets' retention system, 3 models were found to roll forward excessively (33 to 45 degrees), indicating a higher possibility of exposing the user's rear part of the head during accidents.
The visors of all 5 models produced no sharp splinters upon impact. Their optical qualities remained good even after abrasion.
The Council found that some less expensive motorcycle helmets bear only markings indicating compliance with standards which have not been approved in Hong Kong, or bear no compliance marking at all. Consumers should refrain from buying these helmets as they do not meet the legal requirement.
According to the Road Traffic (Safety Equipment) Regulations, motorcyclists and passengers on motorcycles must wear approved protective helmets. When shopping for crash helmets consumers should therefore check the markings to ensure that the models meet the approved standards in the regulation. It is not only an offence to wear unapproved helmet, in case of accidents the user's head may not be well protected. In addition, depending on the practical condition and insurance policy, the motorcyclist may not be covered by insurance, and is also liable for the compensation of the passengers' injury or death.
The Council urged the authorities to step up surveillance to remove illegal and substandard helmets from the market and to review the list of approved motorcycle helmet standards in the regulation with a view to including more standards already approved in other countries in the list, so that consumers would have more choices.
Some more tips for motorcyclists when shopping for crash helmets:
- Half-helmets that only cover the upper part of the head are not recommended.
- Choose the closest fit model that does not cause discomfort even after wearing for a long period of time. Try the helmet on for a few minutes to make sure it fits.
- Do not purchase second hand crash helmets.
