The maximum weight allowed for trucks operating in Spain is regulated by strict laws to ensure road transport safety and protect infrastructure. Generally, the maximum authorized mass for trucks (MMA) varies depending on the type of vehicle and its axle configuration. For instance, a trailer with five axles can carry up to 40 tons, while in special cases, such as the transport of 40-foot ISO containers, up to 44 tons is permitted.
This article delves into the current regulations, the most common configurations, and their implications for the transport industry.
The Importance of Maximum Authorized Mass for Trucks
The maximum authorized mass for trucks not only sets legal limits but also optimizes resource use and reduces environmental impact. Additionally, it ensures that land transport is efficient and complies with European standards.
What Is Maximum Authorized Mass?
The maximum authorized mass (MMA) is the total weight a vehicle can handle, including its structure, cargo, fuel, driver, and passengers. This limit is established considering factors such as the capacity of the tires, brakes, and the vehicle’s design.
Regulations in Spain for Maximum Authorized Mass
In Spain, regulations regarding truck weight limits are aligned with European standards. Key examples include:
- Rigid trucks with two axles: Maximum of 18 tons.
- Rigid trucks with three axles: Up to 26 tons.
- Trailers with five axles: Limit of 40 tons.
- Specific transports such as 40-foot ISO containers: Up to 44 tons.
These values may vary depending on special permits or the nature of the cargo.
Common Configurations and Their Authorized Weights
The design of the truck and the number of axles determine its MMA:
- Two-axle trucks: Primarily used for urban transport and light loads.
- Three-axle articulated trucks: Ideal for medium distances and moderate loads.
- Five-axle vehicles: Preferred for international transport of heavy goods.
