Summary
Ng Li Ning v Ting Jun Heng & Anor [2021] SGCA 93 concerned the apportionment of liability in a serious traffic collision at a signalised junction in Clementi Road intersecting Commonwealth Avenue West (“CAW”). The Court of Appeal upheld the trial judge’s apportionment of negligence between the driver of a Nissan proceeding straight through the junction and the driver of a taxi making a discretionary right turn. The accident resulted in the death of a young female passenger in the taxi and injuries to other passengers.
The appellant Nissan driver argued that Singapore case law, together with the Motor Accident Guide (“MAG”) and the Motor Accident Claims Online (“MACO”) outcome predictor, indicates a relatively consistent liability range for the “straight-moving vehicle” in a “Discretionary Right Turn Scenario”. He contended that the trial judge’s allocation—35% liability to the Nissan—was an “outlier” that should be corrected for the sake of certainty and consistency.
The Court of Appeal rejected the appellant’s attempt to treat the scenario as a rigid template. While acknowledging that patterns in prior decisions and guidance tools may assist in broad calibration, the Court emphasised that apportionment is ultimately fact-sensitive. The trial judge’s findings on causative potency, moral blameworthiness, and the specific circumstances at the junction were not shown to be plainly wrong. Accordingly, the Court of Appeal affirmed the apportionment and the associated costs order for the liability trial.
What Were the Facts of This Case?
The collision occurred on Thursday, 19 April 2018 at about 7.30pm at a traffic lights-controlled cross-junction where Clementi Road intersects CAW. The weather and road conditions were favourable: the roads were dry and visibility was good. The junction was described as large, with moderately heavy traffic typical of a weekday evening.
The Nissan, driven by the appellant Ng Li Ning, travelled along CAW towards Boon Lay Way. The taxi, driven by the second respondent Ting Jun Heng (who was the plaintiff at trial), approached from the opposite direction of CAW and was waiting to turn right into Clementi Road towards the Ayer Rajah Expressway (“AYE”). At the time of the collision, the traffic lights were green in favour of the Nissan. For the taxi’s right turn, the “green arrow” had not yet come on, but the taxi driver had a discretion to proceed if it was safe to do so.
The taxi was the first vehicle in the inner right-turning lane. There were other vehicles behind the taxi waiting to turn right, and there were also vehicles waiting in the other right-turning lane on the taxi’s left. Similarly, on the opposite side of CAW, vehicles were waiting to turn right into Clementi Road towards Upper Bukit Timah Road. In this environment, the taxi driver’s decision-making depended on what could be safely observed and whether the path was clear.
Inside the taxi were four passengers, including the first respondent (a rear middle seat passenger) and a young female passenger seated next to the taxi’s rear left window. The collision sequence was captured by in-vehicle video cameras from vehicles waiting immediately behind the taxi and from vehicles stopped at Clementi Road. The video footage recorded both movement and the sound of the impact.
When there was a lull in traffic from CAW in the Nissan’s direction and the lights remained green for that direction, two motorcycles and other vehicles in the turning lanes proceeded to cross the junction. A waiting vehicle in the taxi’s left adjacent lane—referred to at trial as the “unknown vehicle”—also started to move forward. The taxi then followed the unknown vehicle after a moment or two. Importantly, it was not disputed that the taxi driver merely followed the unknown vehicle without ensuring it was safe to do so, and his view to the left was partially obstructed by the unknown vehicle.
As the unknown vehicle completed its crossing, the Nissan entered the junction. The Nissan narrowly missed colliding with the rear end of the unknown vehicle. However, 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 briefly. The taxi spun across the junction and crossed the front view of vehicles stopped at Clementi Road heading towards Upper Bukit Timah 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 began to reverse and ended up along the stretch of Clementi Road leading to the AYE.
At trial, the first respondent sued the drivers of the Nissan and the taxi. The liability trial focused on contributory negligence and apportionment between the first respondent (rear middle passenger in the taxi), the taxi driver, and the Nissan driver. The allegation against the first respondent was that he was not wearing a seat belt. The trial judge accepted that seat belt use was irrelevant to the occurrence of the collision itself, but considered it relevant to the injuries flowing from the accident. On the evidence, however, it was not proved that the first respondent did not put on his seat belt, and the trial judge held that he was not contributorily negligent for his injury. The appellant did not appeal that finding.
What Were the Key Legal Issues?
The primary legal issue on appeal was whether the Court of Appeal should interfere with the trial judge’s apportionment of liability between the taxi driver and the Nissan driver. The trial judge had found that the taxi driver bore greater responsibility and apportioned liability at 65% to the taxi driver and 35% to the Nissan driver.
Within that broad issue, the appellant framed the case as belonging to a particular pattern of accidents: what he called the “Discretionary Right Turn Scenario”. In such scenarios, a straight-moving vehicle proceeds with the traffic lights in its favour while another vehicle makes a discretionary right turn into its path. The appellant argued that local case law shows a consistent liability range of 0% to 20% for the straight-moving vehicle in most cases, with only two “outlying” decisions allocating 30% and 40% respectively. He contended that the trial judge’s 35% allocation to the Nissan was inconsistent with this established equilibrium.
A secondary issue concerned the relevance and weight of guidance tools and predictive mechanisms. The appellant relied on the MAG and the MACO outcome predictor, submitting that they recommend or predict a lower liability share for the straight-moving vehicle (around 15% or 20%). He argued that allowing the trial judge’s “outlier” approach to stand would undermine certainty in motor accident liability and could lead to unnecessary litigation.
How Did the Court Analyse the Issues?
The Court of Appeal began by restating the factual findings and the trial judge’s approach. The trial judge had considered the video footage, the parties’ evidence, and expert evidence. The Court accepted that the Nissan had the right of way at the junction and that the taxi driver should bear greater liability. However, the trial judge also identified contributory fault on the part of the Nissan driver.
On the taxi driver’s conduct, the trial judge found want of due care. The taxi driver failed to keep a proper lookout when making the right turn and proceeded by simply following the unknown vehicle without ensuring that it was safe to do so. The Court of Appeal treated this as a significant lapse because the taxi driver’s view to the left was partially obstructed, yet he proceeded in reliance on the movement of another vehicle rather than on a clear assessment of the Nissan’s approach.
On the Nissan driver’s conduct, the trial judge accepted that the Nissan was travelling above the speed limit. The trial judge concluded that the Nissan’s speed was between 74 and 87 km/h, with an average speed of 82 km/h. Even the lower end of that range exceeded the 70 km/h limit. The trial judge further found that the Nissan driver failed to exercise due care when approaching a large and busy junction with moderately heavy traffic. Although the Nissan had the lights in its favour, the Court of Appeal agreed that right of way does not eliminate the duty to take reasonable care to avoid collision.
Crucially, the trial judge did not attribute the collision solely to speeding. The Court of Appeal noted that the trial judge held that the primary responsibility for the collision could not be attributed to the Nissan’s speeding. Instead, the causative potency and moral blameworthiness lay chiefly with the taxi driver’s failure to ensure safety before turning. This reasoning supported the 65%/35% split rather than an extreme allocation.
Turning to the appellant’s “Discretionary Right Turn Scenario” argument, the Court of Appeal addressed the attempt to convert patterns in prior decisions into a near-formula. The Court acknowledged that previous cases can provide useful reference points, and that the MAG and MACO predictor may assist in understanding typical outcomes. Nevertheless, the Court emphasised that apportionment is inherently fact-specific. Differences in visibility, traffic density, the timing of movements, the nature of the turning manoeuvre, and the extent of obstruction can all affect the relative blameworthiness and causative potency.
In this case, the Court of Appeal considered that the trial judge’s findings were supported by the evidence, particularly the video footage showing the taxi’s approach and the Nissan’s late detection of the taxi. The Nissan driver had seen the unknown vehicle moving across the junction but did not slow down near the junction because he was confident that his Nissan would not collide with the unknown vehicle. He did not see the taxi until it was too late. The Court of Appeal treated this as a meaningful contributory factor, even if the taxi driver’s negligence remained the dominant cause.
As for the appellant’s reliance on the MAG and MACO, the Court of Appeal did not treat those tools as binding. Guidance tools are designed to assist with consistency, but they cannot override the judicial duty to assess liability on the evidence in the particular case. The trial judge’s apportionment was therefore not displaced merely because it did not align neatly with the appellant’s preferred range.
Finally, the Court of Appeal applied the appellate standard for disturbing apportionment findings. Unless the trial judge’s apportionment is shown to be plainly wrong or based on an error of principle, appellate intervention is generally unwarranted. The Court found no such error. The trial judge had properly weighed the relative causative potency and moral blameworthiness of both drivers and had explained why the Nissan’s speeding and failure to slow down contributed to the collision.
What Was the Outcome?
The Court of Appeal dismissed the appeal and upheld the trial judge’s apportionment of liability: 65% against the taxi driver (second respondent) and 35% against the Nissan driver (appellant). The practical effect was that the appellant remained liable for 35% of the damages attributable to the first respondent’s injuries, subject to the remaining steps in the litigation process.
The Court also left intact the trial judge’s costs order for the liability trial, where both drivers were ordered to pay the first respondent costs fixed at $95,000 (excluding disbursements). The appellate decision thus confirmed both the liability split and the financial consequences flowing from it.
Why Does This Case Matter?
Ng Li Ning v Ting Jun Heng & Anor is significant for motor accident practitioners because it reinforces the principle that apportionment of negligence cannot be reduced to a mechanical application of “scenario” categories. While Singapore courts recognise patterns in contributory negligence outcomes, this case illustrates that courts will still scrutinise the specific factual matrix—particularly the turning driver’s lookout and decision-making, the straight-moving driver’s speed and approach to the junction, and the timing of movements within the traffic flow.
For litigators, the decision also clarifies the limits of reliance on the MAG and MACO outcome predictor. These tools may support arguments about consistency and typical outcomes, but they do not bind the court. Where the trial judge has made evidence-based findings on causation and blameworthiness, appellate courts are unlikely to recalibrate liability merely to align with a predicted percentage.
From a broader jurisprudential perspective, the case contributes to the ongoing development of Singapore negligence law in the context of traffic collisions. It underscores that right of way and traffic light control are relevant but not determinative. Even where a driver has the green lights, the duty of care remains active, and failure to slow or to maintain an adequate lookout can attract contributory negligence.
