Madras HC Acquits Bus Driver: High Speed Alone Cannot Prove Rash or Negligent Driving Under Section 304-A IPC

The Madras High Court set aside conviction of a bus driver for causing death by negligence, holding that high speed without independent proof of rashness cannot sustain charges under Sections 279 and 304-A IPC.

The Madras High Court has acquitted bus driver Udhayakumar of charges under Sections 279 and 304-A of the Indian Penal Code, 1860, overturning his conviction by the III Additional Sessions Judge, Chennai in a 2014 road accident that killed a 60-year-old auto-rickshaw driver on the Durgabai Deshmukh Flyover, Adyar. Justice G. Arul Murugan, sitting singly, found that the prosecution's entire case rested on the premise that the bus was travelling at high speed — but neither the eyewitness accounts nor any other material on record independently established rash or negligent driving. The High Court held that the trial court's inference of criminality from speed alone was legally unsustainable and the conviction suffered from perversity and infirmity.

The Accident and the Trial Court's Findings

On 3 November 2014 at approximately 7.00 a.m., a private bus bearing registration number TN-21-AU-4015 collided with an auto-rickshaw (TN-07-AZ-0799) on the Durgabai Deshmukh Flyover. The auto-rickshaw driver, aged about 60 years, sustained head and elbow injuries and was taken to Royapettah Hospital in an ambulance. He died on the same day. The first informant (PW1), who was driving a car on the bridge at the time, lodged a complaint. The investigating officer (PW9), a Traffic Inspector, registered FIR Crime No. 898/AM3/14 at J-2 Adyar Police Station.

The prosecution examined nine witnesses and exhibited eleven documents, including the FIR, Observation Mahazar, Rough Sketch, Motor Vehicle Inspection Reports for both vehicles, the inquest report, the post-mortem certificate, and the medical certificate of the accused. PW7, the doctor who examined the accused, noted a smell of alcohol, but no blood test was conducted. The post-mortem doctor (PW8) opined that the deceased died due to shock and coma arising from multiple injuries.

The final report charged Udhayakumar under Sections 279 and 304(ii) of the IPC and Section 185 of the Motor Vehicles Act. The trial court acquitted him of Section 304(ii) IPC (culpable homicide not amounting to murder) and Section 185 of the Motor Vehicles Act, finding those charges unproved. However, it convicted him under Section 279 IPC — rash driving on a public way — and Section 304-A IPC — causing death by a rash or negligent act. He was sentenced to six months simple imprisonment for Section 279 and one year simple imprisonment for Section 304-A, with both sentences to run concurrently and a fine of Rs. 1,000.

The Legal Issue: What Must the Prosecution Prove?

Section 279 IPC punishes whoever drives a vehicle on a public way in a manner so rash or negligent as to endanger human life or likely cause hurt. Section 304-A IPC punishes whoever causes death by a rash or negligent act not amounting to culpable homicide. Both provisions require independent proof of rashness or negligence — the mere occurrence of an accident or the fact of speed is not sufficient.

The appellant's counsel argued that the trial court had conflated high speed with rashness and that PW1's credibility was undermined by his own admission in cross-examination. Counsel for the State maintained that the combined evidence of PW1 and PW2, the absence of any mechanical defect in either vehicle as found by the Motor Vehicle Inspector (PW6), and the absence of defence evidence together justified the conviction.

How the High Court Reasoned

Justice G. Arul Murugan anchored the analysis in two Supreme Court decisions. In State of Karnataka v. Satish, (1998) 8 SCC 493, the Supreme Court held that “high speed is a relative term” and that driving at high speed does not, by itself, bespeak negligence or rashness. The prosecution must bring material on record to explain what high speed means in the facts of the case. That judgment also cautioned that criminality cannot be presumed and that the burden of proof rests throughout on the prosecution.

In Ravi Kapur v. State of Rajasthan, (2012) 9 SCC 284, the Supreme Court held that negligence may be gathered from attendant circumstances with the aid of the doctrine of res ipsa loquitur, but only after the factum of accident is established and after ruling out the possibility that the victim's own actions or a third party caused the accident.

Applying both decisions, the High Court turned to the specific evidence against Udhayakumar. PW1, who was driving a car behind the bus, testified that the bus hit the auto while travelling at high speed from North to South. In cross-examination, however, PW1 admitted that he had not noticed on which side of the road the auto was being driven immediately before the collision. The High Court found this admission significant: PW1 had no opportunity to observe the auto's movements just before impact and therefore could not reliably speak to whether any negligent act by the victim auto driver contributed to the accident.

The Rough Sketch (Ex. P9) showed a bifurcation of road near the point of accident on the bridge. The High Court observed that PW1's account — that the bus was rashly driven at that precise location — was not credible when he could not say on which lane the auto was travelling. PW1 also did not state any approximate speed of the bus.

PW2, who was riding a two-wheeler on the bridge, deposed that the bus overtook him at speed and then hit the auto. The High Court noted that PW2 “has not said anything about rash or negligent driving by the accused” — his evidence went only to high speed, not rashness. The accounts of PW1 and PW2 were also internally inconsistent. PW1 said he was driving his car behind the bus; PW2 said a car was proceeding in front of him behind the auto. Neither account corroborated the other regarding the sequence of vehicles, making even the claim of high speed unreliable.

The trial court had reasoned that because the bridge was a one-way road, there was no justification for the bus to travel fast, and therefore high speed itself amounted to negligence. The High Court rejected this squarely: such an inference cannot be sustained in law. The trial court had effectively presumed rashness and negligence from speed, which is precisely what the Supreme Court had prohibited in State of Karnataka v. Satish.

The High Court also addressed the alcohol angle. Although PW7 noted a smell of alcohol on the accused, no blood test was done and the trial court itself had found the Section 185 Motor Vehicles Act charge not proved. The High Court did not treat the smell of alcohol as a substitute for proof of rash or negligent driving.

On the res ipsa loquitur point, the court held the doctrine could not be applied here because the role played by the auto at the time of the accident had not been ruled out. PW1's inability to say on which side the auto was driven meant the prosecution had not excluded the possibility of contributory conduct by the deceased. Without that exclusion, the doctrine from Ravi Kapur could not be invoked to draw an inference of negligence against the accused.

The High Court concluded that there was no independent evidence establishing that Udhayakumar drove the bus in a rash and negligent manner. The finding of the trial court was not supported by sufficient evidence and suffered from perversity and infirmity.

Outcome

Criminal Appeal No. 512 of 2022 was allowed. The conviction and sentence imposed by the III Additional Sessions Judge, Chennai under Sections 279 and 304-A IPC were set aside. Udhayakumar was acquitted of all charges. Any bail bond executed by him was ordered cancelled. Any fine amount already paid was directed to be refunded. The judgment was pronounced on 16 September 2026.
