Contributory Negligence in Road Accidents Scotland

What Is Contributory Negligence?

Contributory negligence is a legal doctrine under the Law Reform (Contributory Negligence) Act 1945 that allows a court to apportion responsibility between the parties to an accident. Where the claimant was partly to blame — whether for causing the accident itself, or for failing to take steps to minimise their own injuries — the court reduces the compensation award by the percentage of blame attributed to them. The remainder is recoverable from the negligent defendant.

How Contributory Negligence Is Assessed

Contributory negligence is assessed on two bases: (1) causative contribution to the accident itself — for example, a pedestrian who stepped into the road without looking, or a cyclist who failed to have working lights; and (2) failure to mitigate personal injury — most commonly, not wearing a seatbelt or motorcycle helmet, which does not cause the accident but increases the severity of injuries. Both may reduce compensation, and both may apply in the same claim.

Common Contributory Negligence Findings in Scotland

Scottish courts have made contributory negligence findings in the following common situations:

• No seatbelt — typically 25% where no injury would have occurred with seatbelt; 15% where injuries would have been less severe (Froom v Butcher [1976])
• Motorcyclist without a compliant helmet — percentage varies with the head injury consequences
• Cyclists without lights at night — percentage varies with circumstances
• Pedestrians crossing without looking or at inappropriate locations
• Passengers knowingly travelling with a drunk, impaired or uninsured driver
• Speeding where this contributed to the severity of the accident

Seatbelt Deductions — Froom v Butcher

The leading authority on seatbelt deductions is Froom v Butcher [1976] QB 286, which is applied by Scottish courts. The guidelines are: 25% reduction where the injuries would not have occurred at all if a seatbelt had been worn; 15% reduction where the injuries would have been significantly less severe. The deduction applies only to the injuries that would have been prevented — not to unrelated injuries that the seatbelt could not have mitigated.

Passengers and Impaired Drivers

Passengers injured in a vehicle driven by someone who was drunk, drugged or impaired can claim — whether against the driver or, where the driver was uninsured or untraced, through the Motor Insurers' Bureau (MIB). However, where the passenger knew or ought to have known of the driver's impairment before getting into the vehicle, a contributory negligence deduction may apply. The size of the deduction depends on the degree of impairment known to the passenger and the circumstances.

Negotiating Contributory Negligence

Contributory negligence findings are often negotiated between the parties rather than determined by a court. Insurers may allege contributory negligence as a tactic to reduce their exposure. Your solicitor will investigate the full circumstances and argue for the lowest possible finding. In some cases, an allegation of contributory negligence can be resisted entirely where the evidence does not support it.
