The C4d sign means you cannot enter or use the road if you are driving a goods vehicle or an animal-drawn vehicle. You must find another way to your destination. This is a strict prohibition, not a suggestion.
The C4d sign specifically prohibits 'automóveis de mercadorias' (goods vehicles, typically vans and lorries used for carrying goods) and 'veículos de tracção animal' (animal-drawn vehicles, like carts pulled by animals). Passenger cars are generally permitted unless otherwise indicated by an additional panel.
If you are driving a goods vehicle or an animal-drawn vehicle, you must not proceed past the C4d sign. You need to stop safely and find an alternative route that is permitted for your vehicle type. This often means looking for signs that indicate specific routes for lorries or carts.
The C4d sign itself generally has no exceptions for the stated vehicle types unless a supplementary panel is present. These panels might specify a limited number of vehicles, a particular time of day, or exempt certain types of goods vehicles. Always check for any additional panels below the main sign.
Yes, the C4d sign is a regulatory sign and should be interpreted alongside other traffic control devices. This includes road markings, traffic lights, and police directions. It is also common to see it with supplementary panels that modify its scope, or near signs indicating the end of a restriction.
A common exam trap is not fully understanding what constitutes a 'goods vehicle' or assuming the prohibition only applies to large trucks. The sign is broader and includes vans used for commercial purposes. Another trap is failing to look for and interpret any supplementary panels, which can significantly alter the sign's meaning for specific drivers.
