Clear answers to common questions about the Temporary Vertical Signs road sign category. Use this FAQ to review tricky rules, understand how these signs appear in exam scenarios, and remove confusion that often leads to mistakes in the Portuguese driving theory exam in Portugal.
Temporary vertical signs are critical because they override normal road rules and layouts. They are implemented to manage immediate situations like roadworks, accidents, or diversions, ensuring the safety of road users and workers. Ignoring them can lead to dangerous situations, confusion, and failed theory tests.
When you encounter a series of temporary signs, it's essential to read them in the order they appear. Usually, signs indicating a change (like a diversion or lane closure) will be followed by signs that confirm the new path or provide further instructions. Slow down, anticipate the changes, and follow the sequence of signs carefully.
The main difference is their duration and authority. Permanent signs are part of the established road infrastructure, while temporary vertical signs are put in place for a limited time to manage specific, short-term conditions. During the period these temporary signs are active, they take precedence over any conflicting permanent signs.
A diversion sign (ST4, ST8a, ST8b) indicates that your normal route is blocked, and you must follow a marked alternative path to get back to your intended destination or a main road. A lane closure sign (ST2, ST6) typically means one or more lanes on your current road are closed, and you'll need to merge into an open lane, often with narrowing traffic lanes (ST6).
The 'Circulation Alternada' or 'Alternating Traffic' sign (ST10) indicates that traffic flow is managed to alternate in each direction, usually due to a single lane being used for two-way traffic. This often happens in areas with temporary obstructions or narrow passages. You will typically need to wait for oncoming traffic to clear before proceeding or follow directions from traffic controllers.
