Understanding where overtaking is forbidden is a fundamental part of the Portuguese theory exam. This guide details the mandatory prohibitions established by the Instituto da Mobilidade e dos Transportes, helping you identify dangerous areas like blind curves, intersections, and level crossings where maneuvers are strictly regulated. Mastering these concepts ensures you can safely navigate Portuguese roads and confidently answer tricky exam questions regarding maneuver legality.

Mastering the rules regarding overtaking is a critical component of the Portuguese driving theory exam, as defined by the Código da Estrada. Overtaking involves significant risks, including increased speed, lateral movement, and the potential for interaction with oncoming traffic or vulnerable road users. To succeed in your IMT theory test, you must be able to recognize not only when overtaking is permitted but also the specific situations where it is strictly prohibited.
In Portugal, the legislation governing overtaking is primarily contained within Article 41 of the Código da Estrada. This article outlines the specific locations where this maneuver is considered dangerous and therefore illegal. For the theory exam, it is vital to memorize these locations, as questions frequently present a diagram or description of a road scenario and ask you to determine if the maneuver is permissible.
According to the law, overtaking is prohibited in the following circumstances:
Remember that these prohibitions are absolute. Even if you believe the road is clear, you cannot initiate an overtaking maneuver in any of the locations listed above. Identifying these "trick" exam scenarios is often about recognizing the road geometry—such as a curve or a pedestrian crossing—rather than just checking for oncoming traffic.
Road markings, particularly longitudinal lines, serve as visual indicators of where overtaking might be restricted. A continuous white line represents a legal barrier that you are forbidden to cross. If the lane adjacent to you is marked with a continuous line, you are generally prohibited from crossing it to overtake. However, in scenarios where a road has two or more lanes in the same direction, you may change lanes to pass, provided you do not cross into the lane designated for opposing traffic.
When overtaking vulnerable road users such as cyclists, the law requires that you maintain a sufficient lateral distance to ensure their safety. While the Código da Estrada emphasizes the need for caution, the golden rule for learners is to prioritize safety over speed. If you are on a narrow road or near a curve, you must wait until it is safe and legal to overtake, even if it means following a cyclist or a slower vehicle for a significant distance.
The minimum distance required to see ahead clearly to complete an overtaking maneuver safely without forcing an oncoming vehicle to reduce its speed or change its trajectory.
Overtaking prohibitions under Article 41 of the Portuguese Código da Estrada cover seven specific scenarios including crests, curves, intersections, level crossings, and pedestrian crossings where the maneuver is strictly forbidden regardless of apparent road conditions. Road markings, particularly continuous white lines, serve as visual legal barriers indicating where overtaking is prohibited, and you may only change lanes to pass when no such line separates your lane from the one you wish to enter. The Distance of Visibility for Overtaking (DVU) concept is essential for determining whether sufficient clear road exists to complete the maneuver safely, and you must always maintain adequate lateral distance when passing vulnerable road users. Recognizing these prohibited locations and understanding road marking rules are critical for both safe driving in Portugal and success in the IMT theory exam.
A short set of high-value points that capture the most important ideas from this article.
Overtaking is prohibited at crests, hills, curves, and any location where visibility is insufficient to see oncoming traffic clearly.
Overtaking is forbidden immediately before and within intersections, level crossings, and pedestrian or bicycle crossings.
A continuous white line on the road marks a legal barrier that you cannot cross to overtake, even if the road appears clear.
You cannot overtake when another vehicle is already in the process of overtaking a third vehicle, and you must wait until that maneuver is complete.
When overtaking vulnerable road users such as cyclists, you must maintain a sufficient lateral distance to ensure their safety.
Article 41 of the Código da Estrada is the legal source for all overtaking prohibitions in Portugal.
On a two-way road with multiple lanes in the same direction, you may change lanes to pass without crossing into opposing traffic, provided no continuous line is crossed.
The Distance of Visibility for Overtaking (DVU) is the minimum clear distance needed to complete an overtake safely.
Road sign C3 explicitly prohibits overtaking for all motor vehicles except two-wheeled motorcycles without a sidecar.
Even if you believe the road is clear, you cannot initiate overtaking in any of the prohibited locations listed in Article 41.
Assuming overtaking is allowed when no oncoming vehicle is visible, even in prohibited locations like curves or crossings.
Believing a continuous line is a suggestion rather than a legal barrier that cannot be crossed.
Confusing the rules for lane changes on multi-lane roads with overtaking restrictions on two-way single-lane roads.
Forgetting that overtaking is prohibited both immediately before AND within level crossings, intersections, and crossings.
Attempting to overtake a vehicle that is itself already overtaking a third vehicle.

Find clear and practical answers to common questions learners often have about Overtaking Prohibitions in Portugal. This section helps explain difficult points, remove confusion, and reinforce the key driving theory concepts that matter for learners in Portugal.
Overtaking is prohibited on hills, at or immediately before level crossings, intersections, pedestrian or cyclist crossings, in curves with reduced visibility, and in any location where visibility is insufficient or the road width is inadequate.
A continuous line represents a legal barrier that cannot be crossed. If a continuous line is on your side of the road, you are prohibited from crossing it, effectively banning overtaking maneuvers that require entering the opposite lane.
No, it is strictly forbidden to overtake immediately before or on pedestrian and cyclist crossings as it creates a severe hazard for vulnerable road users.
Prohibitions do not apply when the road has two or more lanes in the same direction, provided the maneuver does not require entering the lane intended for traffic moving in the opposite direction.
