Firm annotation
Section 229 sits in the Chapter on Offences Causing Public Dangers and protects the physical way itself. The things it names are a public way, a floodgate, a weir and a dam, the last three qualified as forming part of a public way, together with an aircraft landing or take-off area. It does not name a bridge, and a dam that is not part of a public way falls outside it. The conduct is drawn as widely as possible, doing anything by any means, and the offence is complete once one of those things is put into a condition likely to endanger traffic: actual harm is not required, and the danger guarded against is danger to traffic rather than to the public at large. It carries imprisonment of up to five years, a fine of up to 100,000 baht, or both. It complements Sections 226 to 228 by protecting the way and its structures rather than only the signalling aids, and because it falls within Sections 226 to 237 it feeds Section 238, which raises the penalty sharply where the offence causes death or grievous bodily harm, and Section 239, which covers the negligent form.
Why this matters in practice
The provision reaches conduct like digging up a road, undermining a dam that carries a public way, or blocking an aircraft landing area, and it bites once the interference is likely to endanger traffic, before any accident happens. Two scoping points decide many cases. First, the floodgate, weir or dam must form part of a public way: an irrigation dam standing on its own is outside the section, whatever is done to it. Second, the section names no bridge, so a charge framed around a bridge has to be tied back to the public way itself. It is a public-danger offence prosecuted by the State and is not compoundable, so no settlement with an affected owner will end it, and if the interference causes death or grievous bodily harm the far heavier Section 238 applies. Defence work usually turns on whether the structure was public, whether it formed part of a public way, whether the accused caused the condition, and whether danger to traffic was genuinely likely; see our overview of criminal law in Thailand.

Foire aux questions
Quelles structures sont protégées par l'article 229 ?
A public way, and a floodgate, a weir or a dam forming part of a public way, together with an aircraft landing or take-off area. Two points are easy to get wrong: the section does not name a bridge, and the floodgate, weir and dam are covered only where they form part of a public way, so a dam standing on its own is outside it. The offence is putting any of those things, by any means, into a condition likely to endanger traffic.
Quelle est la sanction prévue par l'article 229 ?
Une peine d'emprisonnement pouvant aller jusqu'à cinq ans, une amende pouvant atteindre 100 000 bahts, ou les deux, avec des peines plus lourdes en cas de blessure ou de décès.
