It specifies that the rule, restriction, or permission indicated by the primary sign applies exclusively to vehicles that are currently equipped with snow chains. If your vehicle is not using snow chains, the main sign's instruction may not apply to you, but always confirm your vehicle category and road user status before proceeding.
This M4j sign specifically designates rules applicable only to vehicles equipped with snow chains. Master its meaning for accurate decision-making during your French theory test revision and ensure you comply with specific traffic sign explanations.

They are essential where a restriction or permission does not apply to everyone. Drivers should check whether their vehicle, load, trailer, or purpose falls within the category before continuing.
