RSA chief: Donegal tragedy raises 'hard questions'

The chief executive of the Road Safety Authority says "hard questions" need to be asked after last week's horrific road accident in Donegal in which eight people died.

Eight men were travelling in a Volkswagen Passat on the Clonmany to Buncrana road when it collided with a Toyota Corolla. The seven passengers died instantly and the driver remains in hospital.
