The law of tort

Dylan, who recently passed his driving test, decides to drive into town. The music was loud, and Dylan was texting on his smart phone whilst driving his car. At the junction of Abbey Road, he did not realise that the lights had turned red for the pedestrians to cross. He knocked into Hannah who was walking across the road without looking for oncoming cars. Hannah suffered a broken leg and injured her shoulder because of the accident. Advise Hannah on the course of action against Dylan under the law of tort and explain any defences that Dylan would be able to raise. Support your answer with the relevant case laws.
