The H42 sign, officially 'Velocidade média', indicates that the road section is subject to average speed checks. This doesn't mean you can speed between cameras, but that your overall average speed will be monitored. It's crucial to use this information for planning your speed, lane choice, and observation, rather than as an excuse to ignore general traffic rules. Always combine its information with road markings, traffic lights, and other regulations to ensure safe driving.
Master the H42 Average Speed sign, crucial for your Portuguese theory test revision and understanding traffic rules. This sign indicates a section of road subject to average speed control, requiring careful observation to ensure compliance with legal speed limits and safe driving practices.
H42 - Velocidade média (Velocidade média) belongs to the Portuguese information signs category in the Regulamento de Sinalização do Trânsito. It uses the official information-sign format for its function, often a rectangular or square panel with a symbol, word, route, or facility indication. The official wording is: Velocidade média: indicação de via sujeita a controlo de velocidade, através do cálculo da velocidade média. It gives official information about the road environment, services, restrictions, facilities, or conditions that should influence safe planning. For theory preparation, connect the sign to a concrete driving decision: where to look, when to slow, whether to stop or yield, which route or lane to choose, and whether any panel changes the scope of the rule. On the road, interpret it together with markings, traffic lights, police directions, temporary works signs, and any additional panel placed with it. A strong exam answer explains both recognition and behaviour: not only what the sign is called, but what a safe and lawful driver must do next.
H42 - Velocidade média (Velocidade média) means that the driver must understand and apply this official Portuguese instruction: Velocidade média: indicação de via sujeita a controlo de velocidade, através do cálculo da velocidade média. In practical terms, you should use the information to plan speed, lane position, route choice, stopping, parking, or observation without treating it as permission to ignore other traffic rules.
Get clear, practical answers to the most common questions about the H42 - H42 - Velocidade média (Velocidade média) road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Portuguese driving theory exam in Portugal.
The H42 sign means the road you are on is monitored for average speed. Your speed will be calculated between two points, so maintaining a consistent, legal speed is essential. It's an information sign that requires drivers to plan their journey and speed accordingly.
When you see the H42 sign, you should adjust your driving to maintain a consistent and legal average speed for the monitored section. Use this information to plan your route and speed, but remember to still adhere to all other traffic rules, including lane discipline and general speed limits that may apply.
The H42 sign is an information sign indicating average speed control, not a direct speed limit. While it implies a target average speed that must not be exceeded, it's distinct from signs that impose a maximum instantaneous speed. You must drive in a way that your average speed over the monitored distance is legal.
A common mistake is treating the H42 sign as permission to drive faster than the posted speed limit between cameras, assuming you can make up time. Learners might also forget that general traffic rules and other signs still apply. The exam often tests your understanding that 'average speed' is calculated over a distance, not just at a single point.
No, you must not ignore the H42 sign. It indicates that your speed will be monitored over a distance. Driving at variable speeds, speeding excessively and then slowing down significantly, can still result in exceeding the average speed limit for that section and lead to a penalty.
