The Transport Minister says his department is looking into ways of slowing the increase in vehicles on the Island's roads.
During House of Keys questions David Anderson revealed there were currently 64,000 privately owned cars, vans and bikes, which had increased by about 2000 per year over the last five years.
East Douglas MHK Brenda Cannell, who'd asked for the figures, wondered what was being done to slow this growth before it reached an unsustainable level.
She also wanted to know if there were any plans to tackle the problem of so-called "gas guzzlers".
Mr Anderson said there was a commitment to look at both of these issues:
Man treated for non-life threatening injuries following Ramsey incident
Two suspects in custody following Ramsey incident
Consultation open on plans to formally recognise the heritage of Douglas Head
Police dealing with 'serious incident' in Ramsey
Drop-in session to support Isle of Man charities
