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.
