This guide helps you avoid common mistakes that lead to dangerous situations and theory exam failures, ensuring confident navigation of these busy junctions.
Article content overview
Navigating roundabouts, or 'rotundas' as they are known in Portugal, is a fundamental skill for any driver aiming to pass their IMT theory exam and drive safely on Portuguese roads. These junctions, while designed to improve traffic flow, can often be a source of confusion due to varying designs and the critical priority rules that govern them. Understanding precisely how to approach, enter, circulate within, and exit a roundabout is paramount. This comprehensive guide, aligned with the Código da Estrada and the standards set by the Instituto da Mobilidade e dos Transportes (IMT), will demystify Portuguese roundabouts, ensuring you can tackle them with confidence and avoid common errors that could jeopardise your driving success.
The most crucial aspect of navigating any roundabout in Portugal is understanding who has priority. Unlike some countries where entry traffic might have priority, in Portugal, the golden rule is that vehicles already circulating within the roundabout have priority over those wishing to enter. This principle is consistently applied across all types of roundabouts, whether they are single-lane or multi-lane, in urban or rural settings. Failure to yield to circulating traffic upon entry is a common mistake, often leading to dangerous situations and is a frequent point of testing in the IMT theory exam.
This means that as you approach a roundabout, you must be prepared to stop and wait for a safe gap in the traffic flow. Drivers entering the roundabout should never assume they have priority; instead, they must actively check for oncoming vehicles and only proceed when it is safe to do so without forcing existing traffic to brake or swerve. This is particularly important when approaching from the right, as you may be tempted to assume entry is clear, but vehicles on the roundabout will still have precedence.
The most common and dangerous error drivers make is entering a roundabout without yielding to vehicles already circulating. This can lead to serious accidents, especially in busy multi-lane roundabouts. Always be prepared to stop.
The approach to a roundabout requires careful observation and planning, especially regarding lane discipline and signalling. Before even reaching the yield line, you should position your vehicle in the appropriate lane based on your intended exit. This initial positioning is critical for safe circulation and avoiding last-minute, potentially hazardous manoeuvres within the roundabout itself.
For a single-lane roundabout, your lane choice is straightforward: typically, the right lane is used for exits leading off to the right or straight ahead, while left lane usage would be for specific scenarios or if indicated by signage. However, with multi-lane roundabouts, the decision becomes more nuanced. Generally, if you intend to take the first exit (usually to the right) or go straight ahead, you should position yourself in the right-hand lane. If your destination is further around the roundabout, such as a U-turn or an exit on the left, you should use the left-hand lane.
As you approach the yield line, you must check for traffic in the roundabout. This involves looking to your left for vehicles already circulating. If the way is clear, you can enter. If there is traffic, you must wait. Never assume that other drivers will anticipate your actions. Signalling your intention to enter is not mandatory unless you are changing lanes to enter the roundabout, but careful observation of other road users is key.
Portugal's Código da Estrada provides clear guidance on lane usage within multi-lane roundabouts, and adhering to these rules is essential for both safety and exam success. The fundamental principle is to use the lane that best suits your intended exit, and crucially, to signal correctly when you intend to exit.
For a standard multi-lane roundabout, the lanes are generally designated as follows:
When in doubt about lane usage in a multi-lane roundabout, consider your intended exit. If it's an early exit, use the right lane. For later exits or a U-turn, use the left lane. Always observe other traffic and road markings for specific guidance.
It is vital to understand that once you are in a lane within the roundabout, you should generally remain in that lane until you reach the point where you will exit. Changing lanes inside a roundabout is a manoeuvre that requires extreme caution, similar to changing lanes on any other road. You must signal your intention to change lanes and ensure that the new lane is clear, paying particular attention to any vehicles in your blind spot. Many accidents occur because drivers fail to signal their lane changes or do so too late, leading to collisions with vehicles in adjacent lanes.
The decision of which lane to use is based on your destination. You should choose the lane that most directly leads to your desired exit. For instance, if you are exiting at the second or third exit, using the right lane from the very start is incorrect, as it forces you to cut across the path of other vehicles or undertake a lane change within the roundabout that might be unsafe or illegal depending on the roundabout's design and markings.
One of the most frequently tested and commonly overlooked aspects of roundabout navigation in Portugal is signalling your exit. Failing to signal correctly, or not signalling at all, is a significant cause of accidents and a sure way to incur penalties on your driving licence and in the IMT theory exam.
As you approach your intended exit within the roundabout, you must signal your intention to leave the circulating roadway. This is done by activating your right-hand indicator. The signal should be activated before you reach the exit you intend to take, giving ample warning to any vehicles waiting to enter the roundabout or those in adjacent lanes who might be affected by your departure.
The timing of this signal is important. It should not be activated too early, which could confuse other drivers about your intentions if you were continuing around the roundabout, but it must be activated early enough to be effective. A common guideline is to activate your right-hand signal as you pass the exit before the one you intend to take. This provides clear communication to all road users.
Always signal your intention to exit the roundabout to the right. This applies even if you are taking the first exit or if the roundabout is empty. Proper signalling is a fundamental rule of the Código da Estrada and a key testing point.
If you find yourself needing to correct your path or if you've missed your intended exit, do not attempt sudden, dangerous manoeuvres. Instead, continue circulating within the roundabout until you can safely exit or manoeuvre back into the correct lane to attempt the exit again on a subsequent circuit. Circling the roundabout again is always preferable to a dangerous manoeuvre.
Navigating roundabouts effectively involves more than just basic priority and signalling. Portuguese roads present various roundabout configurations, and understanding how to handle them, along with common errors to avoid, is crucial.
One common scenario involves vehicles in mission urgente de socorro (vehicles on urgent relief missions). These vehicles, with activated flashing lights and audible signals, have priority over all other traffic, including those already in a roundabout. Drivers must always be prepared to yield to such vehicles.
A frequent mistake learners make is hesitating too long at the entry point. This indecision can cause traffic to build up and create confusion for other drivers. If there is a safe gap, you should enter. If not, stopping and waiting is the correct procedure, but a prolonged, unnecessary hesitation is a driving fault.
Do not attempt to overtake within a roundabout. This is a dangerous manoeuvre that is prohibited and will be heavily penalised. Roundabouts are designed for circulating and exiting, not for overtaking.
Another pitfall is mistaking roundabout priority rules for those at other intersections. While some intersections might require yielding to the right at unmarked junctions, roundabouts in Portugal exclusively give priority to traffic already within the circle. Furthermore, if specific signs are present, such as a 'Give Way' (Sign B1) or 'Stop' (Sign B2) sign at the entry to the roundabout, these must be obeyed, overriding the general rule if they impose further restrictions. However, most roundabouts in Portugal operate under the general priority rule where vehicles inside have precedence.
In cases where a driver has made a mistake and needs to reverse direction, this should never be done within the roundabout itself. If you miss your exit, continue circulating to a safe place to leave the roundabout and then find a new route, possibly using a roundabout later on to correct your course. Reversing inside a roundabout is extremely dangerous and illegal.
Understanding the rules for roundabouts is a cornerstone of the Portuguese driving theory test. The IMT frequently includes questions that assess your comprehension of priority, lane discipline, and signalling within these junctions. Often, questions will present scenarios with multiple lanes, different exit intentions, and the presence of other vehicles, requiring you to identify the correct course of action.
Pay close attention to questions that test:
Practice questions will often involve visual aids showing a roundabout and asking about the driver's next action. Always refer back to the fundamental rule: yield to traffic already in the roundabout.
Mastering Portuguese roundabouts is a critical step towards obtaining your driving licence. By internalizing the priority rules, understanding lane discipline, and diligently signalling your exits, you will not only be better prepared for your IMT theory exam but also a safer, more confident driver on Portugal's roads.

In Portugal, vehicles already circulating within the roundabout have priority. You must yield to them before entering.
For roundabouts with multiple lanes, use the lane most convenient for your intended exit. Generally, the right lane is for the first exits, while inner lanes are for later exits or U-turns. Always signal your intention to exit.
You should signal your intention to exit the roundabout by activating your right turn signal before reaching your chosen exit. Signaling upon entry is generally not required unless you are immediately taking the first exit and need to indicate your intention to turn right.
A common error is failing to signal your exit. Drivers must signal right before their intended exit to alert other road users. Another mistake is changing lanes inside the roundabout without checking if it is safe.
Yes, it is generally permitted to make a U-turn in Portuguese roundabouts, typically from the innermost lane. You must yield to all other traffic and signal appropriately.
