Dangerous Driving Causing Death

The Statutory Definition of Dangerous

A person is to be regarded as driving dangerously within the meaning of subsection (1) if—

(a) the way he drives falls far below what would be expected of a competent and careful driver; and

(b) it would be obvious to a competent and careful driver that driving in that way would be dangerous.

(5) A person is also to be regarded as driving dangerously within the meaning of subsection (1) if it would be obvious to a competent and careful driver that driving the motor vehicle concerned in its current state would be dangerous.

(6) For the purposes of subsections (4) and (5), dangerous refers to danger either of injury to any person or of serious damage to property.

In HKSAR v Lam Ho Yin (CACC 11/2010), applying R v Conteh [2004] RTR 1, the Court of Appeal emphasised that dangerous driving has a high threshold and differs from careless driving in degree.

• High Threshold for Dangerous Driving: Adopting the UK precedent R v Conteh, the court emphasized that the law sets a very high bar for a manner of driving to be legally labelled as dangerous. The prosecution must satisfy both strict objective criteria: the driving must fall far below competent standards, and the danger must be completely obvious to a reasonable driver.
• Consequence vs. Conduct: The Court of Appeal explicitly ruled that a tragic or severe outcome does not automatically dictate the nature of the driving offence. A driver cannot be convicted of dangerous driving simply because someone died; the court's focus must remain squarely on the fault in the driver's behaviour before the crash.

In HKSAR v Lam Chi Fat [2012] 1 HKLRD 961, the Court of Appeal confirmed that the manner of driving must be assessed objectively: serious injury or death does not by itself prove that the driving was dangerous, and an intention to drive dangerously is not an element of the offence.

• What Constitutes Dangerous Driving: The prosecution must point to specific acts that show a blatant disregard for road safety. The court identified indicators of dangerous driving, including:
• Severe, excessive speeding, especially in adverse weather.
• Deliberate non-compliance with critical traffic signs, such as running red lights or ignoring pedestrian crossings.
• Consciously operating a heavily overloaded or visibly poorly maintained vehicle.
• Driving while consciously knowing that one is medically unfit, severely ill or intoxicated.

Death

The prosecution must prove beyond a reasonable doubt that the accused's dangerous driving caused another person's death. It is not enough to prove dangerous driving followed by a death: the prosecution must establish the necessary causal connection between the driving and the fatal outcome. The dangerous driving need not be the only cause, but it must remain an operating and substantial cause of death; a later independent act may break the chain of causation.
