A moment of inattention set off a chain of collisions that would reshape multiple lives
In the summer of 2023, a single glance at a mobile phone behind the wheel of a lorry in Singapore ended the life of Emeritus Professor Tan Yock Lin, a 70-year-old legal scholar, and set in motion a reckoning that would stretch across two years of courts and consequences. The driver, Natarajan Mohanraj, was not merely inattentive in one moment — he had been warned, penalized, and still continued driving after the fatal crash. A Singapore court has now answered that pattern of disregard with a lifetime ban from the road and more than two years in prison, a sentence that speaks not only to one man's choices but to the weight societies place on the covenant of care we owe one another in shared public space.
- A lorry crossed a center divider at speed, uprooting trees and tearing through oncoming traffic — all because a driver looked down at his phone.
- The chain reaction crushed a senior law professor's car so severely that rescue workers needed nearly an hour to free him from the wreckage before he died of his injuries.
- What transformed a tragedy into a damning legal case was the discovery that Mohanraj had already been flagged as a careless driver and ordered to surrender his license weeks before the crash.
- Even after the fatal collision, Mohanraj continued driving other people's lorries — twice intercepted by traffic police, once for not wearing a seatbelt — compounding the original offense with open defiance.
- A Singapore court has now imposed a lifetime driving ban alongside a prison sentence, drawing a firm line between negligence and a pattern of willful disregard for the law.
On a July afternoon in 2023, Natarajan Mohanraj was driving a lorry through Singapore when he looked down at his mobile phone. The vehicle crossed the center divider, tore through metal railings, uprooted two trees, and plowed into oncoming traffic. The lorry struck the car of Emeritus Professor Tan Yock Lin, a 70-year-old senior law professor at the National University of Singapore. The impact spun Tan's vehicle into a van, which then struck a bus — leaving three vehicles damaged and multiple people injured.
Tan was trapped inside the crushed wreckage. Singapore Civil Defence Force officers worked for nearly an hour to extract him. The road was closed for close to three hours. Tan was rushed to hospital but died of his injuries before noon that same day.
What deepened the case against Mohanraj was his history. Just weeks before the crash, Traffic Police had issued him a notice ordering him to surrender his driving license by July 25 — the collision occurred two weeks before that deadline. After the fatal accident, his license was formally revoked. He drove anyway. In January 2024, he was stopped for not wearing a seatbelt while driving another man's lorry. In May 2024, he took the same lorry without permission and was intercepted again.
On Friday, a Singapore court sentenced Mohanraj to two years and one month in jail, fined him SGD2,000, and imposed a lifetime ban from driving any motor vehicle in Singapore. He had pleaded guilty to multiple charges, including causing death by driving without due care. The sentence addressed not only the life lost in a moment of distraction, but the sustained pattern of disregard that surrounded it — before the crash, and long after.
On a July afternoon in 2023, a moment of inattention behind the wheel set off a chain of collisions that would reshape multiple lives and end one. Natarajan Mohanraj, a 28-year-old construction worker, was driving a lorry through Singapore when he glanced down at his mobile phone. That split second of distraction sent the heavy vehicle across the center divider, tearing through green metal railings, uprooting two trees, and launching into oncoming traffic.
The lorry struck a car driven by Emeritus Professor Tan Yock Lin, a 70-year-old senior law professor at the National University of Singapore. The impact was violent enough to spin Tan's vehicle into the front of a nearby van, which then veered left and collided with a bus. The chain reaction left three vehicles damaged and multiple people injured. A van driver suffered fractured ribs. But the worst damage was contained in Tan's car, now crushed beyond easy recognition.
Tan had suffered fractures to his skull and was trapped inside the wreckage. Singapore Civil Defence Force officers spent nearly an hour working to extract him from the vehicle. The road itself became a scene of recovery and investigation—closed for almost three hours while crews removed the damaged vehicles, cleared debris, and worked to free the professor. Tan was rushed to the hospital but died of his multiple injuries shortly before noon that same day.
What made the case more damning was Mohanraj's history. Traffic Police had issued him a notice in June 2023—just weeks before the accident—ordering him to surrender his driving license by July 25. The collision occurred two weeks before that deadline, suggesting he was already known to authorities as a careless driver. Yet even after the fatal crash, even after his license was revoked, Mohanraj continued to drive. In January 2024, he drove another man's lorry with permission and was stopped by traffic police for not wearing a seatbelt. In May 2024, he drove the same lorry again without permission before being intercepted once more.
On Friday, a Singapore court sentenced Mohanraj to two years and one month in jail and fined him SGD2,000. The court also imposed a lifetime ban from driving any motor vehicle in Singapore. He had pleaded guilty to multiple charges, including causing death by driving without due care. The sentence reflected not only the gravity of taking a life through negligence, but the pattern of disregard that preceded and followed it—a driver who knew the rules, ignored them, and continued ignoring them even after the worst possible consequence had already occurred.

What strikes you most about how this unfolded?
The timeline. He was already flagged as a careless driver. The system gave him a warning. And then, before that warning even expired, he killed someone.
And after the accident itself?
He kept driving. Twice. After his license was revoked. It suggests something deeper than a momentary lapse—a refusal to accept the rules applied to him.
The victim was a professor. Does that detail matter to the story?
It matters because it shows the randomness of it. Tan Yock Lin was established, accomplished, 70 years old. His life wasn't hanging by a thread. And then a construction worker looking at his phone ended it. That's the collision the story is really about.
The extraction took an hour.
Yes. That detail haunts the whole thing. He was alive when they started. The road was closed. Everyone could see what had happened. And still, it took an hour to get him out.
Do you think the sentence was proportionate?
I don't know. Two years and a lifetime ban. He killed someone through negligence and then ignored the law afterward. But proportionality assumes we can measure a life against time in prison. We can't. What we can measure is whether the sentence might change how the next driver holds their phone.
