Summary
Ng Li Ning v Ting Jun Heng & Anor ([2021] SGCA 93) is a Court of Appeal decision concerning the apportionment of liability in a serious road traffic accident involving two vehicles at a signal-controlled junction. The collision occurred at about 7.30pm on 19 April 2018 at the intersection of Clementi Road and Commonwealth Avenue West (CAW). A Nissan travelling along CAW with the traffic lights in its favour collided with a taxi that was making a discretionary right turn into Clementi Road. The accident resulted in the death of a young female passenger in the taxi and injuries to other passengers.
The High Court had apportioned liability at 65% against the taxi driver and 35% against the Nissan driver. On appeal, the Nissan driver argued that the trial judge’s apportionment was inconsistent with a body of local authorities and with tools used in practice, including the Motor Accident Guide (MAG) and the Motor Accident Claims Online (MACO) outcome predictor. The Court of Appeal, however, upheld the trial judge’s approach and conclusion, emphasising that apportionment is fact-sensitive and that “certainty” in motor accident liability should not override the need to assess causative potency and moral blameworthiness in the particular circumstances.
What Were the Facts of This Case?
The accident took place at a traffic-light controlled cross-junction where Clementi Road intersects CAW. The roads were dry and visibility was good. The Nissan, driven by the appellant, was travelling along CAW towards Boon Lay Way. In the opposite direction, a taxi driven by the second respondent was waiting to turn right into Clementi Road towards the Ayer Rajah Expressway (AYE). The taxi was positioned as the first vehicle in the inner right-turning lane at the junction.
At the material time, the traffic lights were green for the Nissan’s direction. For the taxi’s right turn, the “green arrow” had not yet come on. Nevertheless, the taxi driver had discretion to proceed across the junction if it was safe to do so. There were vehicles behind the taxi also waiting to turn right, and there were vehicles in the other right-turning lane on the taxi’s left. Similarly, on the far side of CAW, vehicles were waiting to turn right into Clementi Road in the direction of Upper Bukit Timah Road.
During a lull in traffic from CAW (the Nissan’s direction) while the lights remained green, two motorcycles and other waiting vehicles in the turning lanes proceeded across the junction. The taxi followed shortly thereafter. Critically, the taxi driver’s view to his left was partially obstructed by an “unknown vehicle” that had also started moving. The trial judge found that the taxi driver merely followed the unknown vehicle without ensuring that it was safe to do so.
As the unknown vehicle cleared the junction, the Nissan entered the junction and narrowly missed colliding with the unknown vehicle. Unfortunately, the taxi was then in the path of the Nissan. The Nissan smashed into the taxi’s left side with such force that the Nissan’s tyres were lifted off the road momentarily. The taxi was sent spinning across the junction and crossed in front of vehicles stopped at Clementi Road. The rear left female passenger’s head was seen swinging outside the taxi’s rear left window, with the glass apparently shattered. She died at the scene. The taxi then reversed and ended up along the stretch of Clementi Road leading towards the AYE.
What Were the Key Legal Issues?
The principal legal issue was the apportionment of liability between the two drivers in a negligence claim arising from a road traffic collision. Specifically, the Court of Appeal had to determine whether the High Court’s allocation of 65% liability to the taxi driver and 35% to the Nissan driver was correct in law and fact, having regard to the relative causative potency and moral blameworthiness of each driver.
A secondary issue concerned contributory negligence of the plaintiff passenger in the taxi. The allegation was that the plaintiff was not wearing a seat belt. The trial judge, however, treated seat belt usage as irrelevant to the occurrence of the collision itself, focusing instead on whether it was proved that the plaintiff’s injury was caused or worsened by the absence of a seat belt. The trial judge found that it was not proved that the plaintiff did not put on his seat belt and therefore did not apportion contributory negligence to him. The appellant did not appeal against this finding, so the Court of Appeal did not need to revisit it.
How Did the Court Analyse the Issues?
The Court of Appeal began by setting out the factual matrix in detail, relying on video footage recorded by in-vehicle cameras. The footage captured the sequence of vehicles at the junction and the impact, including the loud sound of the collision. This evidential foundation mattered because apportionment in negligence cases often turns on fine-grained assessments of what each driver did (or failed to do) immediately before the collision.
On the taxi driver’s conduct, the Court of Appeal accepted the trial judge’s finding of want of due care. The taxi driver proceeded to make the right turn by following the unknown vehicle without ensuring that it was safe to do so, and his view to the left was partially obstructed. In a discretionary right-turn scenario, the driver’s duty is not displaced by the presence of a green light for the opposing traffic. Rather, the discretionary nature of the turn means the taxi driver must still ensure that the manoeuvre can be completed safely, including maintaining a proper lookout and taking account of vehicles that may be approaching at speed.
On the Nissan driver’s conduct, the Court of Appeal noted that the Nissan had the right of way at the junction. However, right of way does not provide a licence to drive without due care. The trial judge found that the Nissan was travelling above the speed limit (between 74 and 87 kmph, with an average of 82 kmph). The appellant accepted he was speeding. The trial judge also found that the appellant failed to exercise due care when approaching the junction, even though he had seen the unknown vehicle moving across the junction. The appellant did not slow down near the junction and did not see the taxi until it was too late.
In addressing the appellant’s argument about consistency and “judicial thinking”, the Court of Appeal considered the “Discretionary Right Turn Scenario” framework advanced by the appellant. The appellant relied on a range of local decisions and submitted that liability against the straight-moving vehicle in such scenarios is typically between 0% and 20%, with only two outlying decisions at 30% and 40%. He further argued that the MAG and the MACO outcome predictor reflect a recommended 15% liability against the straight-moving vehicle, and that the predicted outcome of 20% liability aligned with the bulk of cases.
The Court of Appeal’s response was, in substance, that tools and patterns in prior cases can be informative but cannot substitute for the court’s duty to assess the specific facts. Apportionment is not a mechanical exercise. The court must weigh causative potency and moral blameworthiness. Here, the trial judge had already considered these factors and concluded that the taxi driver’s failure to keep a proper lookout and to ensure safety before proceeding was the dominant cause of the collision. At the same time, the Nissan driver’s speeding and failure to slow down or see the taxi in time were not negligible. The Court of Appeal therefore treated the High Court’s apportionment as a reasoned evaluation rather than an aberration requiring correction.
Importantly, the Court of Appeal also addressed the appellant’s “certainty” argument. While predictability is desirable in motor accident litigation, the pursuit of certainty cannot override the fact that each junction, each traffic configuration, and each driver’s immediate actions may differ. The Court of Appeal implicitly cautioned against treating the MAG or outcome predictors as binding rules of liability. These tools may assist settlement and case management, but they do not determine legal liability where the evidence shows materially different conduct or causative dynamics.
What Was the Outcome?
The Court of Appeal dismissed the appeal and upheld the High Court’s apportionment of liability at 65% against the taxi driver and 35% against the Nissan driver. The practical effect was that the Nissan driver remained liable for 35% of the damages attributable to the negligence found against him, despite his attempt to align the outcome with the general pattern he identified in prior cases and with the MAG/MACO guidance.
The decision therefore reinforces that, even in recurring traffic scenarios, courts will continue to conduct a fact-specific analysis. The outcome also preserves the trial judge’s findings on key factual matters, including the taxi driver’s failure to ensure safety when following an obstructed vehicle and the Nissan driver’s speeding and failure to slow down or detect the taxi in time.
Why Does This Case Matter?
Ng Li Ning v Ting Jun Heng is significant for practitioners because it clarifies how courts approach apportionment in motor accident negligence claims, particularly where there is a discretionary right turn by one vehicle and a straight-moving vehicle with the traffic lights in its favour. The case demonstrates that the “scenario” label—while useful for organising case law—does not eliminate the need for careful evaluation of causative potency and moral blameworthiness in the specific circumstances.
For litigators and insurers, the decision is also a caution against over-reliance on aggregated statistics, guides, or outcome predictors. The MAG and MACO predictor may be relevant in assessing likely outcomes and supporting settlement discussions, but they do not bind the court. Where the evidence shows that one driver’s conduct is materially more blameworthy or causatively potent—such as failing to keep a proper lookout in a discretionary turn—courts may depart from the “typical” range suggested by prior cases or tools.
Finally, the case contributes to the broader jurisprudence on contributory negligence and seat belt allegations. Although the seat belt issue did not drive the appeal (because the appellant did not challenge the trial judge’s finding that it was not proved the plaintiff failed to wear a seat belt), the underlying reasoning reflects a principled approach: seat belt usage may be relevant to injury outcomes rather than collision occurrence, but the evidential burden remains crucial.
