점자블록 30cm 클레임 팩트체크

Claim

"South Korean accessibility regulations require at least 30 cm of unobstructed space on both sides of tactile paving."

Why This Claim Matters

Tactile paving (점자블록, literally "Braille blocks") is one of the most visible pieces of accessibility infrastructure on Korean sidewalks, and it is frequently obstructed in practice — by parked bicycles, sandwich boards, utility cabinets, and street vendors. A claim about a specific legal clearance requirement is the kind of statement that gets repeated in accessibility advocacy, journalism, and international comparisons of disability law, often without anyone tracing it back to the actual statute. If the number is wrong, or if a design recommendation gets reported as a legal mandate, that matters for anyone using the claim to argue for enforcement, to compare Korea against other countries, or to cite in a policy brief. Getting the distinction between "the law requires X" and "an advocacy group recommends X" right is the whole point of checking a claim like this rather than repeating it.

Research Method

This claim was decomposed before any search was run: does a 30cm figure appear in Korean statute at all; if so, does it measure block size, a front-of-hazard offset, or a lateral both-sides clearance; is whichever figure exists a binding legal requirement or a design recommendation; and does the claim's "on both sides" framing match what the source actually says.

Sources were pursued in priority order — Korean statutes first, then government ministries, then local-government design guidelines, then national technical standards, then academic literature, then disability organizations, then other secondary sources — with primary legal text always preferred over summaries of it. Two statutes were located and downloaded as PDF attachments directly from the National Law Information Center (law.go.kr) and read in full with `pdftotext`, rather than relying on a search snippet or a third party's restatement of what they say. Several other leads (a Ministry of Land, Infrastructure and Transport administrative guideline; Seoul's detailed sidewalk design drawings; the national tactile-block product standard KS F 4561) could not be retrieved due to access failures and are logged as open gaps rather than silently dropped.

Evidence

The two statutes that actually govern tactile-paving installation in Korea are the enforcement rule (시행규칙) under the *Act on the Guarantee of Promotion of Convenience of Persons with Disabilities, the Aged, Pregnant Women, etc.*, and the enforcement rule under the *Pedestrian Safety and Convenience Promotion Act*.

The first contains the only two "30cm" (0.3m) figures connected to tactile paving found anywhere in primary legal text:

• Block size: "the flooring [tactile block] must be at least 0.3m × 0.3m" — a manufacturing/installation dimension for a single block unit, unrelated to clearance from obstacles.
• Pre-hazard offset: "dot-type warning blocks must be laid 0.3m in front of turning points, level changes, and hazard locations" — a spacing rule that applies in the direction of travel, before a hazard. The same statute repeats this 0.3m-in-front pattern for building entrances and low service-counter fronts.

The second statute defines tactile block color and the functional difference between point-type and linear blocks, but contains no dimensional or clearance figure of any kind.

Neither statute specifies any distance requirement for obstacle-free space running alongside — on both sides of — a tactile paving strip.

A real "no obstacles on both sides" concept does exist in Korean accessibility practice, but not at 30cm. Korea Blind Union's own installation-principle document states: "no obstacle of any kind should exist within at least 60cm, centered on the linear block, left and right." A 2025 article from the affiliated Support Center for Convenience Facilities for the Visually Impaired repeats the same 60cm figure and, unusually, explains its own derivation: the Center combined the statute's 30cm pre-hazard offset with a separate, unrelated bollard-spacing rule to arrive at 60cm as its *own recommended minimum*, explicitly describing this as guidance rather than a quotation of law.

That is the most evidenced explanation this research turned up for how a claim like the one being tested could arise: a real 30cm figure exists in Korean statute, but it measures block size or a pre-hazard offset, not a both-sides clearance zone — and the actual figure Korean disability advocates use for a both-sides clearance zone is double that, and is a recommendation, not a regulation.

Source Assessment

The two statutes are the strongest possible evidence for this claim: primary legal text, read directly rather than through a summary, from Korea's official legal-information portal. Both are unambiguous and leave little room for alternative interpretation on the specific point of whether a both-sides clearance figure is codified — it is not, in either one.

The Korea Blind Union documents are credible, specialized, and internally consistent with each other, but they are advocacy and technical-guidance material, not law, and the 2025 article's own account of deriving 60cm from other rules is itself evidence that this number is not a direct statutory quotation. A third source (Korea Welfare Center for the Blind) could not be read reliably due to a text-encoding failure during retrieval and is excluded from the basis for this verdict rather than stretched to fit it. Three additional sources that could plausibly hold a different, authoritative figure — a Ministry of Land, Infrastructure and Transport administrative guideline, Seoul's detailed sidewalk design drawings, and the KS F 4561 national standard — could not be retrieved in this pass; their absence is a real limitation, not a detail glossed over.

Verdict

False. No Korean statute found in this research requires 30cm of unobstructed space on both sides of tactile paving. The 30cm figures that do exist in Korean law govern the tactile block's own physical size and a pre-hazard installation offset — different concepts from a lateral clearance zone. Where a both-sides clearance concept does appear in Korean accessibility guidance, the figure used is 60cm, and it is presented by its own source as a non-binding recommendation rather than a legal requirement. This verdict rests on primary legal text read in full, corroborated by two independent disability-organization sources; it is tempered by three unresolved source gaps disclosed above, none of which changed the pattern found across every source that was successfully retrieved.

Editorial Recommendation

Not publishable as-is; needs revision before use. If this claim is being cited in copy intended for publication, the specific figure and framing should be corrected — either to describe the actual 30cm statutory provisions accurately (block size and pre-hazard offset), or to cite the 60cm both-sides figure with correct attribution to disability-organization guidance rather than to "regulation." Before treating this fact-check as fully closed, the three unresolved sources (the Ministry of Land, Infrastructure and Transport's road-safety-facility guideline, Seoul's detailed sidewalk design drawings, and KS F 4561) should be retrieved and checked; none of the evidence gathered here suggests they would overturn the finding, but a "False" verdict on a specific numeric claim deserves that additional confirmation before it is presented as final rather than as the strongest currently available answer.
