Navigate Portugal's roads with confidence by mastering priority rules at intersections and roundabouts. This unit covers everything from traffic signals and signs to the fundamental right-of-way principles at uncontrolled junctions and the specific procedures for safely handling single and multi-lane roundabouts.

Browse all lessons that make up Priority Rules, Intersections and Roundabouts. Each lesson focuses on specific topics, learning objectives, and core concepts, helping you build essential knowledge and follow a clear, structured progression toward your study goals in Portugal.
This lesson establishes the foundational principles of right-of-way that govern traffic interactions. It explains the hierarchy of traffic control, where signals from a police officer override all other signs and rules. The content clarifies how to proceed at intersections controlled by stop signs, yield signs, and on priority roads, forming the basis for safe junction navigation.
This lesson focuses on the crucial 'priority from the right' rule, which applies at intersections lacking any signs or signals. It details the procedure for approaching such junctions, including reducing speed, performing visual checks, and being prepared to yield to traffic approaching from the right. Mastering this rule is essential for safety in residential areas and on rural roads.
This lesson explains how to recognize priority roads and understand the associated right-of-way privileges. It covers the specific diamond-shaped sign that indicates a priority road and the sign signaling its end. Drivers will learn their responsibilities when traveling on a priority road and the correct procedure for yielding when entering one from a secondary road.
This lesson provides a step-by-step guide to navigating roundabouts in Portugal. It emphasizes the primary rule of yielding to traffic already circulating within the roundabout before entering. The content covers correct lane selection based on the intended exit, proper use of indicators for exiting, and managing the complexities of multi-lane roundabouts.
This lesson serves as a summary of how to interpret various road signs that dictate right-of-way at intersections. It reinforces the distinct actions required for stop signs (complete stop) and yield signs (give way). The lesson also covers signs that illustrate the layout of a junction and indicate which direction the priority road follows, ensuring drivers can make correct and safe decisions.

Find clear answers to the most common questions learners ask about Priority Rules, Intersections and Roundabouts. Understand how the unit is organized, what learning goals it supports, and how it contributes to your study progression with structured explanations and practical guidance tailored for learners in Portugal.
The most important rule for roundabouts in Portugal is to yield to vehicles already circulating within the roundabout when entering, unless specific signage indicates otherwise. Always observe traffic within the roundabout before proceeding. For multi-lane roundabouts, pay attention to lane markings and signs to choose the correct lane for your exit.
At an uncontrolled intersection in Portugal, where there are no traffic lights, priority signs, or police officers directing traffic, the general rule is to yield to vehicles approaching from your right. This is the 'priority-to-the-right' rule. However, always be prepared for other drivers not following the rules and drive defensively.
A 'STOP' sign (sign A1) requires you to come to a complete halt before the stop line or intersection and yield to all traffic before proceeding. A 'YIELD' sign (sign A2), often depicted as an inverted triangle, means you must slow down and yield to traffic that has priority, continuing only when it is safe to do so without forcing other vehicles to stop or change course.
Yes, multi-lane roundabouts require extra attention. You must select the correct lane before entering based on your intended exit. Generally, the left lane is for exiting further around the roundabout or for U-turns, while the right lane is for immediate exits. Always check road markings and signs for specific guidance. Remember to yield to circulating traffic.
In Portugal, trams generally have priority over other vehicles, even at intersections where you might otherwise have the right-of-way. Drivers must yield to trams. Buses, especially when signalling to enter traffic from a bus stop, also require special consideration, though they do not have automatic priority like trams. Always prioritize safety.
To prepare for priority rule questions on the IMT theory test, focus on understanding the hierarchy of right-of-way: police officers first, then traffic signals, then priority signs (STOP, YIELD, priority roads), and finally the 'priority-to-the-right' rule for uncontrolled junctions. Practice with example questions and visualize different intersection and roundabout scenarios.
