Source. 6/1990. (IV. 12.) KöHÉM rendelet a közúti járművek forgalomba helyezésének és forgalomban tartásának műszaki feltételeiről, 5. § A járművek méreteire vonatkozó üzemeltetési műszaki feltételek, in the version marked "Hatály: ( 2026.I.4. - )" at net.jogtar.hu.
The height is the lowest in the whole material, and it applies only to the trailer. 5. § (2) reads in full: "A személygépkocsi pótkocsijának a magassága a 3,00 métert, egyéb jármű magassága a 4,00 métert nem haladhatja meg." — a car's trailer may not exceed 3.00 metres in height, other vehicles not 4.00. Every other paragraph in 5. § carries an asterisk with amendment details; (2) carries none. It is the original 1990 wording, unchanged for thirty-six years, and it lies a full metre below the 4.00 that thirty other countries write.
Hungary has no legal definition of a caravan. 2. § (19) defines lakóautó, the motorhome, as a category M vehicle built to accommodate living; the words lakókocsi and lakópótkocsi do not occur in the instrument. A caravan is therefore a személygépkocsi pótkocsija straight off, and that is precisely the wording 5. § (2) uses. The rule therefore catches the caravan without an interpretive step — unlike most other countries in the material, where one has to reason out whether a goods rule covers a leisure vehicle.
The length paragraph is shared between caravan and motorhome. 5. § (3) divides vehicles into a) bus, b) articulated bus, c) everything else: "egyéb járműnél – kivéve a félpótkocsit –: 12,00 méter". The catch-all c) covers both a személygépkocsi pótkocsija and lakóautó, and they therefore get the same figure from the same point. That is unusual in the material — most countries have one point for the motor vehicle and one for the trailer.
Two further paragraphs have no counterpart anywhere else:
5. § (6): "A gépkocsi hátsó tengelye és az általa vontatott pótkocsi első tengelye közötti távolság nem lehet kisebb 3,00 méternél." — the distance between the car's rear axle and the trailer's front axle may not be less than 3.00 metres. It is the only minimum limit in the whole material. For a normal outfit — rear overhang plus drawbar plus the caravan's front up to the axle — it is passed with a good margin, but a short car with a short single-axle caravan is not obviously above it.
5. § (7) enumerates what may not be counted into the width: the tyres near ground contact and their pressure sensors, snow chains, mirrors that fold away at at most 150 N and then do not project beyond, side indicators and width marker lamps with at most 50 mm projection, and customs seals. The list is a word-for-word transfer of annex 1 point 2 of the Vienna Convention (see below) — the same five points in the same order. Hungary has therefore read the convention as meaning that the national width limit applies, and borrowed the convention's exception list for it.
- § (5) sets 16.40 and 15.65 metres respectively for an outfit, but measures from
"a rakfelület legelső, a vezető fülke mögötti külső pontja" — the foremost point of the load space behind the cab. The rule presupposes a goods vehicle and is not included in the table above.
Do Hungarian dimensions apply to a Swedish-registered caravan?
The question is not rhetorical. 1. § (1) says the regulation applies to vehicles on Hungarian roads, but 1. § (2) adds: "A Bécsben 1968. évi november hó 8. napján aláírásra megnyitott közúti közlekedési Egyezményben részes államok által kiadott hatósági jelzéssel közlekedő külföldi járművekre az Egyezmény 5. számú Függelékében foglalt műszaki előírások az irányadók." — for foreign vehicles bearing an official registration issued by a state party to the Vienna Convention on Road Traffic (Vienna, 8 November 1968), it is the convention's annex 5 that applies. Both Hungary (ratification 16 March 1976) and Sweden (25 July 1985) are parties.
The answer: yes, the Hungarian dimensions apply. Annex 5 contains no dimensions at all. It is called Technical conditions concerning motor vehicles and trailers and consists of four chapters: I brakes, II lamps and reflecting devices, III other requirements (steering, mirror, audible warning, speedometer, windscreen wipers, tyres, coupling device), IV exemptions. No width, no height, no length. The reference in 1. § (2) therefore gives away an area annex 5 does not govern.
The dimensions are instead in annex 1 point 1, and it says the exact opposite: "Contracting Parties may refuse to admit to their territories in international traffic motor vehicles, trailers or combinations of vehicles whose over-all weight or weight per axle or dimensions exceed the limits fixed by their domestic legislation for vehicles registered in their territories." The convention expressly reserves to every party the right to apply its own dimension limits to international traffic. That Hungary has copied annex 1 point 2 into its own width paragraph shows that the country has read it that way.

The amendments to annexes 1 and 5, proposed by Italy and adopted by depositary notification C.N.322.2024 with entry into force 9 February 2025 for all parties, have been read in ECE/TRANS/WP.1/2017/1/Rev.3. They concern articles 25 bis and 32, annex 1 points 2 and 8, and annex 5 chapter I point 18 and the whole of chapter II, which was replaced. Nothing in them concerns dimensions. Annex 1 point 1 is untouched, and annex 5 still has no dimensions chapter.
