Bus Éireann has apologised for a ‘mechanical fault’ which caused the door to fall off a bus travelling to Galway.
The incident happened on Monday morning on the 64 route between Derry and Galway, about an hour after the bus left Sligo.
Passengers were concerned but nobody was injured in the incident.
Fianna Fáil spokesperson on Transport Marc Mac Sharry said there could have been fatal consequences if the door had come off at speed while the bus shared the road with other vehicles.
Deputy Mac Sharry said: “Bus Éireann have been less than reassuring about this incident. I believe they should give more details and give clarity to their customers that this is an isolated problem. They should also clarify how often the safety of vehicles is assessed and if they are aware of other problems on similar routes.
“Bus Éireann must not dismiss this as a ‘mechanical fault’, and if necessary, a full fleet assessment should be carried out. Was this mechanical fault known and if so, why was that particular bus used on the route if there were concerns?”
