Facts
The plaintiff was not wearing a seatbelt whilst driving because he did not like seatbelts and because he had seen drivers being trapped after a crash because they wore a seatbelt. After a crash, the plaintiff suffered head and chest injuries and a broken finger. Had he worn his seatbelt, the head and chest injuries would have been avoided. The crash was entirely the defendant’s fault. The defendant contended that the plaintiff was guilty of contributory negligence. The Queen’s Bench held in favour of the plaintiff on grounds that there was no statutory compulsion to wear a seatbelt at the time. The defendant appealed.
Issues
(1) Does one’s failure to wear a seatbelt amount to contributory negligence under s. 1(1) Law Reform (Contributory Negligence) Act 1945 if their injuries would have been prevented or lessened if they had done so?
Decision / Outcome
The appeal was allowed.
(1) Determining whether one is guilty of contributory negligence is a matter not of the cause of the accident, but of the cause of the damage.
(2) The plaintiff’s injuries, except for the broken finger, were caused by his failure to wear a seatbelt and therefore, he was guilty of contributory negligence.
(3) For this reason, the defendant’s damages should be reduced by 20 per cent.

This case summary accurately reflects the decision in Froom v Butcher [1976] 1 QB 286. The legal principles established by the Court of Appeal remain good law. The case continues to be the leading authority on contributory negligence and failure to wear a seatbelt, and the percentage reductions it set out (20% where a seatbelt would have prevented the injury entirely, 25% in some circumstances, and 15% where it would have made a difference but not prevented injury altogether) are still routinely applied by courts today.
One important contextual development to note: the wearing of seatbelts by front-seat occupants became a statutory requirement under the Motor Vehicles (Wearing of Seat Belts) Regulations 1982 (SI 1982/1203), made under the Road Traffic Act 1972, with effect from 31 January 1983. Rear-seat belt requirements followed later. The statutory framework is now consolidated principally under the Road Traffic Act 1988 and associated regulations. The practical consequence is that failure to wear a seatbelt is now not only a basis for a finding of contributory negligence but also a criminal offence. The Froom v Butcher deductions continue to be applied in personal injury litigation notwithstanding the statutory compulsion, and the case therefore retains full relevance. The article’s observation that there was no statutory compulsion at the time of the accident is historically accurate.
