An extra 14 motorcycle helmet ratings from the UK department for transport's safety helmet assessment and rating programme (SHARP) have been published by road safety minister Mike Penning ahead of the Easter holiday weekend.The ratings take the total number of helmets rated by SHARP to 261.HELMET ADVICEMike Penning said: "Many of us will be getting our bikes out and – with luck – taking advantage of some sunshine over the Bank Holiday weekend."I would urge anyone thinking about buying a new helmet ahead of the start of the summer season to check out the SHARP website before making their decision. A properly fitted helmet with a high SHARP rating will provide you with the best possible protection in the event of an accident so it’s well worth checking the advice on the site before you buy."All helmets must meet minimum legal safety standards to be sold in the UK but the SHARP scheme uses a wider range of tests to provide riders with more information on how much protection a helmet can provide in a crash. The advice will help riders to choose the safest helmet suitable for them.The SHARP tests, which award ratings of between one and five stars, show that the safety performance of helmets can vary by as much as 70%. Motorcyclists represent one percent of UK traffic yet account for 21% of the country's casualties. In 2010, 403 motorcyclists died on UK roads.Find out how safe your helmet is here!
