I think the bigger issue for us is challenging TRL. Its very clear that Richard Cuerden, the reports author and the Technical Director for Vehicle Safety is an avid "don't confuse me with the evidence" plastic hat aficionado. His comment that
“There is no doubt that cycle helmets are effective in a crash, although some anti-helmet advocates still argue the opposite.
says it all with the very worrying additional comment
TRL says its report for Jersey "raises important questions for the rest of the UK – How can cycle helmet wearing rates be increased to help reduce head and brain injuries suffered across all regions of the British Isles? Should the Jersey compulsory cycle helmet wearing legislation be copied elsewhere?"
This is why TRL needs to be challenged about their lack of objectivity - they are after spreading helmet compulsion to the rest of the UK.
