No plans for national speed limit: Isle of Man government
The Manx government has "no plans" to introduce a national speed limit, despite concerns the current system is "putting innocent lives at risk".
Coroner of Inquests John Needham said the state was failing to protect road users by not restricting their speed on some routes.
He was speaking at the inquest of a motorcyclist who crashed when travelling at about 100mph.
But the government has said a speed limit would "not improve road safety".
Infrastructure minister David Cretney said a limit could not be easily enforced and was not supported by the majority of the population.
Every year, thousands of visitors travel to the Isle of Man to watch the TT races and to take the opportunity to ride around the world-famous circuit.
'Seemingly permissive attitude'
Introducing a national speed limit would mean the end of the island's remaining derestricted routes, including a section of the Mountain Road between Ramsey Hairpin and Hillberry - part of the TT race circuit.
Mr Needham, the island's coroner, made his comments at the inquest into the death of motorcyclist David Paul Jones, 33, from Ramsey, who collided with a bin lorry in May 2012.
After delivering a verdict of accidental death, the coroner said that by adopting a "seemingly permissive attitude", the Isle of Man government was failing in its duty to protect road users.
He added that derestricted roads encouraged motorcyclists to ride the TT route as if it was "track day" and he called on the government to "act responsibly".
A government survey in 2006 received 14,575 responses, with 57% rejecting the suggestion of a 60mph national speed limit and 56% rejecting a 70mph limit on the Mountain Road.
