Source: arrêté grand-ducal modifié du 23 novembre 1955, chapitre III, Ire section, in the consolidated version in force from 2026-06-12. All three articles have their present wording from règl. g.-d. du 19 décembre 2020.
| Dimension | Luxembourg | Article |
|---|---|---|
| Width | 2.55 m "pour tous les autres véhicules" (2.60 for temperature-controlled vehicles, 3 m for road and construction machinery) | art. 3 |
| Height | 4.00 m for all vehicles except bicycles and the L category (2.50 m) | art. 6 |
| Length, caravan | 12.00 m (remorque) | art. 4 |
| Length, motorhome | 12.00 m (véhicule automoteur, bus excepted) | art. 4 al. 1 c) |
| Length, outfit | 18.75 m (train routier) | art. 4 |
The motorhome row stands word for word like this in art. 4 first paragraph, which measures un véhicule routier en circulation ne tractant pas une remorque — that is, the vehicle on its own:
c) pour un véhicule automoteur autre que les véhicules automoteurs visés sous
a) et b) et autre qu'un véhicule M2 et M3 (autobus, autocar) : 12,00 mètres
Points a) and b) are micro electric vehicles and bicycles and the L category respectively, so the enumeration is exhaustive: everything motor-driven that is not a bus or a light vehicle gets 12.00 m. A motorhome is un véhicule automoteur and nothing else.
Art. 4 moreover contains the turning-circle requirement: the outfit must fit between an outer circle of 12.5 m and an inner one of 5.3 m. That is a construction requirement on the caravan, not something the driver measures, and it stands here only because the article otherwise looks incomplete when quoted.
Method note: Legilux publishes the code consolidated only as PDF. data.legilux.public.lu/eli/etat/leg/code/route/20260612 answers with an Angular shell of a little over 1 kB whatever the Accept header, and the HTML variants under /fr/html/ give 404. Content negotiation leads instead to the file store: https://data.legilux.public.lu/filestore/eli/etat/leg/code/route/20260612/fr/pdf/eli-etat-leg-code-route-20260612-fr-pdf.pdf, 35 MB and 969 pages, the whole Code de la route in the version in force from 2026-06-12. It was read with our PDF reader. The text comes out with the language marking fr-FR and þÿ artefacts wedged between the words, which makes a search for whole phrases miss; the searches were therefore done on a variant with all whitespace and all fr-FR flattened out first. The earlier note that Legilux could not be reached applied to the HTML view, not to the instrument.
Rules other than these. Alcohol limits, seatbelts, child seats, mobile phones, winter tyres and daytime running lights are not on Campeur and will not be. Your Europe, run by the Commission, has them country by country: road rules in Luxembourg ↗. Do not read it for caravan speed — that cross-check has been made, and the portal was wrong in four countries out of twenty-one.
