Causing hurt by rash or negligent act — s 337 / s 338 themes

Updated for relaunch. This page is general information about Singapore criminal law and procedure for education and search. It is not legal advice, does not create a solicitor–client relationship, and is not a statement by any former operator of this domain. Laws and procedures change — speak with a qualified Singapore criminal lawyer about your situation.

From accident narrative to Penal Code charge

Not every injury case is framed as a fight. Some investigations start from an accident, workplace mishap, traffic collision, or other incident where nobody intended to hurt anyone — yet prosecutors may still consider charges under section 337 or section 338 of the Penal Code if hurt (or grievous hurt) was caused by an act done so rashly or negligently as to endanger human life or the personal safety of others.

This page maps that pathway at a high level. It is not a driving-sentence guide and not a workplace-safety manual. For intentional hurt pathways, see voluntarily causing hurt, voluntarily causing grievous hurt, and VCH vs VCGH injury maps.

Section 337 — causing hurt by rash or negligent act

Section 337 applies where a person causes hurt to any person by doing any act so rashly or negligently as to endanger human life or the personal safety of others. The statute splits punishment into two limbs:

• Rash act — imprisonment for a term which may extend to one year, or fine which may extend to $5,000, or both;
• Negligent act — imprisonment for a term which may extend to 6 months, or fine which may extend to $2,500, or both.

Those figures are the statutory ceilings on the current public SSO text — not “going rates”.

Section 338 — causing grievous hurt by rash or negligent act

Section 338 is the counterpart where the result is grievous hurt (as defined in s 320), again caused by a rash or negligent act endangering human life or the personal safety of others. The current public SSO text provides:

• Rash act — imprisonment for a term which may extend to 4 years, or fine which may extend to $10,000, or both;
• Negligent act — imprisonment for a term which may extend to 2 years, or fine which may extend to $5,000, or both.

Whether injuries are “hurt” or “grievous hurt” is a statutory characterisation issue — see the injury-map page. Whether the act was “rash” or “negligent” is a different, often contested, question.

Rash vs negligent — orientation only

Singapore case law and commentary often treat rashness as involving a higher degree of risk-taking culpability than negligence, but both still sit below intentional “voluntarily causing” hurt. Everyday synonyms (“careless”, “reckless”, “stupid mistake”) are not reliable legal substitutes. The charge sheet and the evidence about what the accused knew, foresaw, or ought to have guarded against will drive the analysis.

Important contrast with VCH/VCGH:

• Sections 321 / 322 — intention to cause hurt / grievous hurt, or knowledge that such hurt is likely, plus the result.
• Sections 337 / 338 — rashness or negligence endangering life or personal safety, plus hurt / grievous hurt as the result.

An incident can be investigated under more than one theory before charges are preferred. Do not assume that calling something an “accident” in conversation prevents a criminal charge — and do not assume every accident becomes one.

Endangering life or personal safety

Both sections require that the act was done so rashly or negligently as to endanger human life or the personal safety of others. That endangerment element is part of what separates these offences from purely civil negligence claims. Proof may draw on expert evidence, industry standards, road rules, CCTV, and the sequence of decisions leading up to the injury.

Other statutes (for example Road Traffic Act offences, workplace safety offences, or specific regulatory regimes) may apply on the same facts. Stacking or choice of charge is fact-specific and outside any single-page tariff. For traffic-oriented clusters see the traffic offences hub and drink driving where intoxication themes appear.

Common fact settings (illustrative only)

Educational readers often arrive from three broad settings. None of these is a closed list of when s 337 or s 338 will be charged:

• Road and transport — collisions where injury occurs and investigators examine speed, distraction, fitness to drive, or failure to keep a proper lookout, sometimes alongside RTA charges;
• Workplace and tools — machinery, falling objects, incomplete isolation of energy sources, or skipped safety steps that endanger co-workers or members of the public;
• Everyday activity — situations where a risky act in a crowded or domestic setting causes injury without an intent to assault.

Medical characterisation under s 320 (grievous hurt) can shift the available section even when the narrative still sounds like an “accident” to laypersons.

Investigation and practical posture

These cases are often document- and expert-heavy: medical reports, scene photos, device data, employment or training records, and statements about warnings ignored or safety steps skipped. Accused persons should preserve relevant records and avoid speculative public posts. Injured parties should obtain prompt medical documentation — the hurt vs grievous-hurt distinction can turn on medical characterisation under s 320.

Caning is not part of the s 337 / s 338 punishment limbs on the current SSO text; caning exposure is more commonly discussed in certain intentional hurt pathways. See caning exposure in hurt offences for statute-constrained orientation elsewhere. Where sexual-privacy or image issues arise from a different incident, see non-consensual intimate images or voyeurism — those are separate clusters.

Civil claims sitting beside criminal exposure

The same injury can generate a police investigation and a civil claim for damages. Settling a civil claim does not automatically extinguish a public prosecution, and a criminal outcome does not by itself fix quantum. If insurers, employers, or platform operators are involved, get advice before signing statements that travel across forums.

Frequently asked questions

If I did not mean to hurt anyone, can I still be charged?

Possibly. Sections 337 and 338 are built around rashness or negligence plus endangerment and resulting hurt/grievous hurt — not around an intention to injure. Whether a charge is preferred depends on the evidence and prosecutorial assessment.

What is the difference between s 337 and s 338?

The result: hurt versus grievous hurt. Both still require a rash or negligent act endangering life or personal safety. Maxima differ under the statute.

Is “rash” the same as “reckless” in everyday English?

Not safely. Use the statutory words and get advice on how local authorities interpret them on your facts.

Will this page tell me the fine I will pay?

No. The figures above are statutory ceilings from the public SSO text, not predicted outcomes. No tariff table is published here.

Can Road Traffic Act charges run together with s 337 or s 338?

On some traffic facts, yes — charge selection and stacking are fact-specific. Counsel should map the actual charge sheet rather than treating this page as a multi-Act matrix.

If you are under investigation after an incident that caused injury — or you are a complainant seeking clarity on possible charges — speak with a qualified Singapore criminal lawyer and bring medical and scene documents.
