A Limited One-Way Street, known as a 'Sens Unique Limité' (SUL) in Belgium, designates a street for one-way motor vehicle traffic while explicitly allowing cyclists to travel in both directions, including against the flow of cars. This specific traffic management strategy is widely implemented in Belgian urban areas to enhance cycling networks and calm traffic. Drivers must be acutely aware of these rules, especially regarding oncoming cyclists, to prevent accidents and comply with Belgian traffic legislation, which is a key part of your driving theory exam.
Sens Unique Limité
A Limited One-Way Street (Sens Unique Limité or SUL) is a road designed for one-way motorized traffic where cyclists are specifically permitted to travel in both directions, often against the flow of vehicles.

See how Limited One-Way Street appears in realistic driving situations relevant to Belgium. These examples explain correct behaviour, safety implications, and how Limited One-Way Street connects to Belgian driving theory exam questions.
You are driving your car and are about to turn right into a narrow street marked as a 'Sens Unique Limité' (SUL) in a Belgian city. As you begin your turn, you notice a cyclist approaching from the opposite direction within the SUL.
You must yield priority to the oncoming cyclist, stopping your vehicle before entering the SUL if necessary, and only proceed when it is safe to do so without impeding their path.
In a SUL, cyclists have the right to travel against the general direction of motor traffic. Drivers turning into such streets must always expect and give way to these cyclists to prevent collisions and ensure road safety, as per Belgian traffic regulations.
You are driving along a SUL in Brussels, keeping to the right side of the road, when you want to park your vehicle on the left side where parking is permitted. After parking, you prepare to open your driver's side door to exit.
Before opening your door, you must thoroughly check both directions, especially behind you for cyclists traveling with the flow of traffic, and ahead of you for cyclists approaching against the flow of traffic, ensuring no cyclist is put at risk.
Even though it's a one-way street for cars, cyclists can come from either direction on a SUL. Opening a car door carelessly (known as 'dooring') is a significant cause of accidents for cyclists. Always apply the 'Dutch reach' or similar method to ensure the road is clear before exiting the vehicle.
You are driving through a residential 'Zone 30' area in Flanders, and you notice a street sign indicating a one-way street for cars with an additional symbol showing a bicycle, signifying a SUL. The street is quite narrow, about 2.8 meters wide.
You should reduce your speed and proceed with extreme caution, being prepared to slow down further or stop if you encounter an oncoming cyclist, especially given the narrow width of the street.
Belgian regulations state that SULs are permitted on streets between 2.6 and 3 meters wide. On such narrow streets, passing an oncoming cyclist requires significant care from motorists to ensure adequate space and prevent accidents, reinforcing the need for vigilance and reduced speed in 'Zone 30' areas.

A Limited One-Way Street, referred to as 'Sens Unique Limité' (SUL) in Belgian traffic law, is a specific type of one-way street where the general rule for motor vehicles to travel in a single direction is modified for cyclists. On a SUL, cyclists are permitted to ride against the flow of motorized traffic, as well as with it. This creates a contraflow cycling arrangement designed to improve connectivity for cyclists, allowing them to take more direct routes and avoid heavily trafficked roads.
The concept of SULs is widely adopted across Belgium, particularly in urban zones and 'Zone 30' areas. This is due to a 2004 Royal Decree that facilitated their implementation. SULs play a vital role in urban planning by enhancing cycling infrastructure, making cities more accessible for cyclists, and effectively contributing to traffic calming by increasing driver vigilance and reducing vehicle speeds. They are a cornerstone of integrated traffic management strategies aimed at promoting sustainable mobility and improving road safety for vulnerable road users.
Drivers must be able to recognise SULs through specific signage. Typically, a standard one-way street sign (a blue rectangular sign with a white arrow pointing in the permitted direction) will be accompanied by an additional panel or marking indicating that cyclists are allowed in both directions. Road markings, such as dashed lines or bicycle symbols, may also be present on the road surface to delineate the contraflow cycling lane, especially in wider streets. It is crucial to pay attention to these visual cues to understand the traffic rules.
When driving on a Limited One-Way Street, motorists must remain extra vigilant. While you are traveling in the designated one-way direction, there is a high probability of encountering cyclists coming towards you. Always expect oncoming cyclists, particularly when entering or exiting the street, at intersections, and when opening vehicle doors if parked. Drivers of wider vehicles (over 2 meters) should be especially careful and prepared to reduce speed significantly or even stop to safely allow cyclists to pass. The reduced speed environment of SULs contributes to cyclist safety by lowering the impact force in potential collisions, but driver awareness is paramount.
Questions about Limited One-Way Streets frequently appear in the Belgian driving theory exam. You might be tested on identifying the relevant road signs, understanding priority rules at intersections involving SULs, and knowing your responsibilities towards cyclists traveling in the contraflow direction. A common trap involves misjudging the presence of cyclists or failing to yield priority where required. Understanding the specific regulations and the emphasis on cyclist safety in Belgium is key to successfully answering these questions and ensuring safe driving practices.

The main difference is that on a regular one-way street, all traffic, including bicycles, travels in a single direction. However, on a Limited One-Way Street (SUL), while motor vehicles are restricted to one direction, cyclists are explicitly permitted to travel in both directions, often against the flow of motorized traffic. This distinction is vital for your Belgian driving theory understanding.
You can identify a SUL by observing the standard blue one-way street sign, which will be accompanied by an additional white panel or road marking (often a bicycle symbol) indicating that cyclists are allowed in both directions. Being able to recognize these specific Belgian road signs is crucial for your theory test preparation and safe driving.
As a driver in a SUL, your primary responsibility is to be extremely vigilant and always anticipate oncoming cyclists, even from the 'wrong' direction. You must yield priority to them when necessary, reduce your speed, and be prepared to stop to ensure their safety. This adherence to safe driving practices is fundamental to Belgian road safety.
Yes, SULs are generally considered safer for cyclists because they allow for more direct routes, reduce the need for cyclists to use busy main roads, and encourage lower speeds for motorized traffic. While drivers need to be more aware of contraflow cyclists, the overall design aims to improve road safety for vulnerable road users in Belgian urban environments.
Parking on a SUL is subject to the general parking rules and local signage. If parking is permitted, you must still exercise extreme caution when opening your vehicle door, checking for cyclists from both directions before exiting to prevent 'dooring' accidents. Always prioritize the safety of cyclists and other road users.
