hi, can you help me solve this question by apply PIRAC

Facts: Forest and his wife Pipistrelle book a bus tour going from Launceston to the Tamar Valley wine region for a short holiday with Jennos Bus Tours. They purchase their tickets from the local travel agent and the tickets are to be collected at the point of departure. Just before getting on the bus, when they are collecting their tickets, they are asked to sign a document that confirms their personal details. They think it is simply a receipt for the tickets.

As they travel out of Launceston, Pipistrelle takes off her seat belt and goes to the baggage compartment to collect a book she is reading. Just as she was doing this, the bus brakes suddenly, Pipistrelle falls and breaks her wrist and suffers nervous shock, which all but ruins the holiday.

When Pipistrelle sues Jennos Bus Tours for damages for damages for her injury and the loss of enjoyment of her holiday, the company draws her attention to a clause in the printed form that she had signed that stated that Jenno Bus Tours was not liable for any injury, howsoever that injury is caused to passengers not wearing a seatbelt.

Required: Advise Pipistrelle whether she can successfully sue the Tamar Valley bus tour operator for damages for her injury and the loss of enjoyment of her holiday.
