Haines v Talbott: High Court apportions liability 70:30 after A30 smoke collision

The High Court has apportioned liability 70:30 in favour of a claimant left with serious injuries after being struck by a van while attempting to leave her broken-down, smoke-emitting car on the A30 in Cornwall, finding that the defendant driver failed to react appropriately to clear warning signs of a hazard ahead.

In Haines v Talbott [2026] EWHC 2130 (KB), Deputy High Court Judge Cathryn McGahey KC held that Ross Talbott's driving fell below the standard expected of a reasonable driver, while finding that Zoe Haines bore 30 per cent responsibility for the collision through her own negligence in causing her car to break down and emit smoke.

Background

The accident occurred on 7 January 2023 when Ms Haines, then 20 years old and 23 weeks pregnant, was driving her Ford Fiesta along the A30 near Bodmin. She had substantially overfilled the engine with oil, causing it to emit large quantities of smoke and lose power. She pulled towards the nearside of the carriageway, though the car remained protruding 60cm into the inside lane, switched off her headlights and engine, and got out through the driver's door without activating her hazard lights.

Mr Talbott, driving a van some distance behind, entered a bank of smoke that had progressively thickened and collided with the open driver's door and with Ms Haines, who was thrown onto the carriageway.

Liability finding

The judge found that Mr Talbott had sufficient warning of a developing hazard, including thickening smoke and the fact that two vehicles ahead of him had moved into the outside lane, apparently to avoid the densest smoke. She held that a reasonable driver would have slowed further or changed lanes before entering the impenetrable patch, rather than assuming, as Mr Talbott did, that the smoke came from a moving or stationary vehicle he would be able to see in time to avoid.

Rejecting the defence submission that Mr Talbott had faced a sudden emergency, the judge found he had recognised the developing hazard but had not responded to it quickly enough, noting the obvious risk of serious injury given the size of his vehicle.

Contributory negligence

Turning to Ms Haines' own conduct, the judge rejected an argument that her youth and inexperience should lower the standard expected of her in maintaining her car, applying the principle in Nettleship v Weston that inexperience does not justify a reduced standard of care.

She found Ms Haines negligent in failing to activate her hazard lights and in switching off her headlights, though neither failure was found to have had any causative effect given the density of the smoke. The judge declined to find her blameworthy for stopping partially on the carriageway or for exiting through the driver's door, accepting these were reasonable reactions to a perceived risk of fire, though she noted both actions were causally significant to the collision occurring.

Weighing blameworthiness and causative potency in the round, the judge assessed Ms Haines' contributory negligence at 30 per cent, holding that the emergency she created did not relieve Mr Talbott of the ordinary obligation on drivers to respond appropriately to hazards they encounter on the road, even unusual ones such as dense smoke.
