The C3d sign means that goods vehicles (automóveis de mercadorias) with a total weight exceeding the tonnage indicated on the sign are prohibited from entering or using this road. You must respect this restriction and find another route if your vehicle falls into this category.
If you are driving a goods vehicle and its total weight is greater than the amount shown on the C3d sign, you must not proceed. You should look for alternative routes or signage that permits your vehicle's access. Do not assume the restriction is optional.
No, the C3d sign specifically prohibits 'automóveis de mercadorias' (goods vehicles) based on their total weight. Other vehicle types, like passenger cars or motorcycles, are not directly affected by this particular prohibition, provided they do not fall under any other restrictions.
A common exam trap is confusing the C3d sign with other weight-related signs or assuming it applies to all heavy vehicles. Remember, it specifically targets goods vehicles above a certain total weight. Always check the indicated weight and the type of vehicle the sign refers to.
Prohibitory signs like the C3d generally remain in effect from the point where they are displayed until they are cancelled by an 'End of Prohibition' sign (like C4) or another sign that modifies the restriction. Always be alert for subsequent signs.
