What is a Roundabout (Rond-point) in Belgium?

In Belgium, a roundabout, or 'rond-point,' is a type of circular intersection designed to keep traffic moving and reduce accident severity. It features a central island that traffic must circulate around in a single direction. Every official roundabout in Belgium is specifically indicated by the D5 traffic sign (a blue circular sign with three white arrows forming a circle). This clear signage is fundamental to how roundabouts function and how priority is determined within Belgian traffic law.

Belgian Priority Rules at Roundabouts

Understanding priority is perhaps the most critical aspect of navigating Belgian roundabouts. According to Belgian traffic law, if an intersection is officially designated as a 'rond-point' (i.e., marked with a D5 sign and typically 'yield' signs B1 or 'stop' signs B5 at its entries):

• Traffic already in the roundabout has priority. Drivers entering the roundabout must yield to vehicles already circulating within it. This is the standard rule for all officially marked roundabouts in Belgium.

The Nuance of 'Priority from the Right'

While the rule for marked roundabouts is clear, learners often confuse it with the general 'priority from the right' rule. In Belgium, 'priority from the right' applies at unmarked intersections where no other priority signs (like D5, B1, B5) or traffic lights are present. Therefore:

• If a circular intersection is NOT marked as an official 'rond-point' (lacking the D5 sign and entry yield/stop signs), it functions as a regular intersection where priority from the right applies. In such a rare case, vehicles entering the circular area would have priority over those already circulating. However, these are not legally 'rond-points' in Belgium, and proper roundabouts always give priority to traffic already inside.

Signaling Requirements at Roundabouts

Correct signaling is vital for communicating your intentions to other road users.

• Entering a roundabout: You are generally not required to signal when entering a Belgian roundabout, unless you intend to take an immediate left turn (which is rare) or if you are turning sharply. Your intention is usually clear based on your approach lane and the path you take.
• Exiting a roundabout: You must signal your intention to exit the roundabout. Activate your right indicator once you have passed the exit before the one you intend to take. This alerts following drivers and those waiting to enter your intention to leave.

Lane Usage in Multi-Lane Roundabouts

When a roundabout has more than one lane, specific rules apply to ensure smooth and safe traffic flow:

• First Exit: If you intend to take the first exit, you should generally approach and enter the roundabout in the rightmost lane. Stay in the right lane throughout your circulation until your exit.
• Subsequent Exits: If you intend to take an exit beyond the first one, you may approach and enter in a lane other than the rightmost lane (e.g., a middle or left lane). While circulating, you should generally move to the rightmost lane after passing the exit immediately preceding your intended exit. This allows you to exit safely without cutting across other lanes.
• Cyclists and Speed Pedelecs: In roundabouts without dedicated cycle lanes, cyclists and speed pedelec riders are not required to keep as close to the right edge of the roadway as other vehicles. This allows them to be more visible and avoid being squeezed by larger vehicles. When exiting, they should position themselves clearly.
