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:
Hospice funding criticised by UK charity chief amid Isle of Man service cuts
Sailings cancelled as storm brings gale-force winds
Manx Mountain Marathon route diverted over safety concerns amid forecast strong winds
Rushen MHKs to meet with Southern Group Practice over appointment concerns
