Kerb weight, referred to as 'tara' in the Portuguese Código da Estrada, defines a vehicle's ready-to-drive mass before any load is added. This includes the weight of the vehicle itself, essential operating fluids, mandatory equipment, and notably, the driver's weight (standardized at 75 kg). Knowing this specific definition is vital for theory test questions concerning vehicle categories, permissible loads, and safety limits on Portuguese roads, ensuring you comprehend the foundational principles of vehicle weight management.
Kerb weight, known as 'tara' in Portugal, is the weight of a vehicle in running order without passengers or cargo, specifically including 90% fuel, all other necessary fluids, tools, a spare wheel if mandatory, the driver (75 kg), and for heavy passenger vehicles, a guide if applicable (75 kg).

You are preparing for a trip in Portugal and loading your passenger car with luggage for three family members. The vehicle's 'tara' is 1400 kg, and its 'peso bruto' (maximum permissible mass) is 1900 kg. Your three family members each weigh about 70 kg, and the driver (you) is also 70 kg.
You must calculate the available payload capacity by subtracting the 'tara' from the 'peso bruto', then subtract the weight of the additional passengers and your own weight (beyond the 75 kg already accounted for in 'tara') from the payload to determine how much luggage you can carry.
The 'tara' already includes a 75 kg driver. Your own weight of 70 kg means you subtract 0 kg from the payload for yourself. The three additional passengers (3 x 70 kg = 210 kg) must be subtracted from the payload. Your available payload is 1900 kg ('peso bruto') - 1400 kg ('tara') = 500 kg. Then, 500 kg - 210 kg (passengers) = 290 kg. Therefore, you can carry a maximum of 290 kg of luggage. Exceeding this would be illegal and unsafe.
A theory exam question for the Portuguese driving test asks for the kerb weight ('tara') of a specific commercial van, providing its empty weight, fuel tank capacity, and stating that it carries a mandatory spare wheel and tools. No driver weight is explicitly mentioned.
When calculating 'tara' for the exam, you must remember to include the standardized 75 kg for the driver, in addition to 90% of the fuel capacity, other fluids, the empty weight, and any mandatory equipment like the spare wheel and tools.
The Portuguese definition of 'tara' explicitly includes the driver's weight (75 kg) and 90% of the fuel, even if not directly stated in the question. Failing to include these components would result in an incorrect answer, as they are integral to the 'vehicle in running order' concept under Portuguese law.
You are driving a light goods vehicle on a Portuguese motorway ('autoestrada') and notice that the handling feels sluggish, and the brakes are less responsive than usual. You suspect your cargo might be exceeding the vehicle's legal limit.
You should safely pull over at the nearest service area or designated stopping point, verify your vehicle's 'tara' and 'peso bruto' (maximum permissible mass) from its documentation, and assess the weight of your cargo to ensure you are within the legal 'carga útil' (payload capacity). If overloaded, you must reduce the cargo before continuing.
Overloading a vehicle beyond its legal 'carga útil' (which is derived from 'peso bruto' minus 'tara') severely impairs its performance, increasing braking distances and reducing maneuverability. This creates a significant safety hazard for you and other road users and is a serious traffic offense in Portugal.
Learn about 'tara', the specific Portuguese definition of kerb weight, including the driver's weight and fuel percentage. Essential for understanding vehicle limits and passing your driving theory exam in Portugal.
In Portuguese driving theory and legislation (Código da Estrada), 'tara' refers to the kerb weight of a vehicle. This is not just the vehicle's empty weight, but its weight in 'running order' without any passengers or cargo. The definition is highly specific and includes several components that are essential for theory exam preparation.
Specifically, 'tara' includes:
This precise definition, especially the inclusion of the driver's weight and a specific fuel percentage, distinguishes 'tara' from general international kerb weight definitions and is a frequent point of focus in driving theory questions in Portugal.
Understanding 'tara' is fundamental for passing your Portuguese driving theory test, particularly for questions related to vehicle categorization, loading limits, and road safety. Exam questions often test your knowledge of how 'tara' contributes to a vehicle's overall mass and how it influences permissible maximum weights (e.g., maximum permissible mass, or 'peso bruto').
Knowing the components of 'tara' helps you correctly calculate or identify when a vehicle is overloaded or what licence category might be required for a specific type of vehicle. Incorrectly assessing a vehicle's weight can lead to unsafe driving conditions, fines, and points on your licence.
The 'tara' of a vehicle has direct practical implications for daily driving in Portugal. It forms the baseline for calculating a vehicle's payload capacity – the maximum weight of cargo and passengers it can legally carry. Exceeding this capacity compromises steering, braking, and overall vehicle stability, increasing the risk of accidents.
For example, if a vehicle has a 'tara' of 1500 kg and a maximum permissible mass ('peso bruto') of 2000 kg, its maximum payload is 500 kg. This payload must account for any additional passengers beyond the driver (who is already included in 'tara') and all cargo. Driving an overloaded vehicle is not only dangerous but also illegal and subject to penalties under Portuguese traffic law.
It's crucial to differentiate 'tara' from other vehicle weight terms that appear in Portuguese driving theory:
Each of these terms plays a specific role in Portuguese road safety and regulatory compliance, and understanding their relationships, particularly with 'tara' as the foundational measure, is key for safe and legal driving.

In Portuguese driving theory, 'tara' (kerb weight) is defined as the weight of a vehicle in running order without passengers or cargo. This specifically includes 90% of the fuel, all other necessary fluids, mandatory tools, a spare wheel (if required), and crucially, the driver's weight, standardized at 75 kg. For heavy passenger vehicles, it also includes a guide's weight (75 kg) if a seat is provided.
The driver's weight (standardized at 75 kg) is included in 'tara' because it's considered part of the vehicle's 'running order' configuration. This unique detail is vital for accurate vehicle weight calculations in theory test questions and reflects the complete operational mass of the vehicle before any additional payload is considered according to Portuguese traffic legislation.
'Tara' directly affects a vehicle's payload capacity ('carga útil') because the payload is calculated by subtracting the 'tara' from the 'peso bruto' (maximum permissible mass). An accurate understanding of 'tara' ensures you can correctly determine how much additional weight (passengers and cargo) a vehicle can legally carry, which is crucial for safe driving and avoiding fines.
No, 'tara' (kerb weight) and 'peso bruto' (maximum permissible mass) are distinct terms in Portuguese driving rules. 'Tara' is the vehicle's weight in running order without payload, while 'peso bruto' is the absolute maximum weight the vehicle is legally allowed to have when fully loaded, including its 'tara' and all passengers and cargo. 'Peso bruto' is always greater than 'tara'.
Exceeding a vehicle's legal weight limit in Portugal, based on its 'tara' and 'peso bruto', significantly compromises road safety. It can lead to longer braking distances, reduced steering control, increased tire wear, and potential damage to the vehicle's suspension. Additionally, it can result in substantial fines and other penalties under the Código da Estrada, impacting your driving licence points.
