Gov' Guidelines on blame/responsibility.......
Learner drivers
Learner drivers who are driving legally are in exactly the same position as any other driver in relation to a traffic accident. The supervisor of a learner driver must do all that is reasonable to prevent the driver from driving in a way likely to cause danger to others. It is the duty of the driver to report an accident and the liability and responsibility of the supervisor depends on the particular circumstances.
The police have the power to require the supervisor of a learner driver to produce their licence and certificate of insurance.
Personally I blame the instructor, they're all feckless!
