It's crucial for understanding that a primary sign's restriction or permission might only apply to specific vehicle categories, such as lorries.

The M4h plate is a supplementary sign used in France to specify which vehicle category or road user the main sign above it applies to. While its title mentions 'lorries', it can represent various vehicle types. It clarifies that a restriction or permission is not universal and affects only the depicted category.
Not necessarily. The M4h plate specifies which category the main sign affects. If your car is not depicted on the M4h plate, then the main sign's instruction likely does not apply to you. However, always confirm this based on the specific symbol shown and your vehicle combination (including any trailer or load).
If your vehicle category is depicted on the M4h plate, you must obey the main sign's instruction. For example, if the main sign prohibits entry and the M4h plate shows a lorry symbol, then lorries must not enter. If the main sign indicates a speed limit and the M4h plate shows a lorry, that speed limit applies specifically to lorries.
A common trap is assuming a sign applies to all vehicles without checking supplementary plates like the M4h. Learners might also misinterpret a symbol, for instance, confusing a general vehicle symbol with one specific to lorries or other types. Always carefully assess the main sign and any accompanying category plates.
While the title is 'Weight of Lorries', the M4h plate is a general category indicator. If the main sign relates to weight restrictions, the M4h plate would specify if this restriction applies to lorries or another depicted vehicle type. It refines the applicability of rules concerning dimensions, weight, or other specific restrictions.
