The technical requirements for quad bikes depends on their intended use. Road or agricultural bikes must be type approved, while those classed as machinery need to meet the Supply of Machinery (Safety) Regulations 2008. Following research by the Health and Safety Executive in Great Britain (HSE) the advice for quad bikes used in workplace settings is that ROPS are not recommended. It was shown that ROPS may lead to an increased risk of injury in the event of an overturn by either preventing the operator from separating from the machine or striking the operator as the machine overturns. The Government plans to consult on replacing the current, interim, approval scheme for road and agricultural quads, with a full type GB scheme. Any new evidence supplied during this process will be given consideration.
