The trial of bendy buses in the Isle of Man will be monitored by independent consultants, and if they prove unsuitable they won't be added to the Bus Vannin fleet.
That promise from Community, Culture and Leisure minister Graham Cregeen who says he understands safety concerns over the number of standing passengers they carry.
Traditional double-deckers carry up to 31 standing while bendy buses on trial in the Island will cater for more than 90. Plans to trial them on school routes have added to controversy.
But the department says bendy buses could save around £300,000 a year in wages and fuel, at a time budgets are facing deep cuts.
So how will the success of trial be judged?
