What is a Roundabout?

A roundabout (rotonde in Dutch) is a specific type of circular intersection designed to minimize conflicting traffic movements. Instead of traffic lights or stop signs at every approach, vehicles travel in one direction (counter-clockwise in the Netherlands) around a central island. This design generally leads to smoother traffic flow and fewer serious accidents compared to conventional cross-intersections.

Types of Roundabouts in the Netherlands

In the Netherlands, you will encounter various types of roundabouts, each with specific characteristics:

• Priority Roundabouts (Voorrangsrotondes): These are the most common type. Traffic on the roundabout always has priority over traffic entering it. This is clearly indicated by the B6 sign ("give right of way to drivers on the intersecting road") and 'shark teeth' road markings (give-way triangles) on the approach roads. Almost all newly constructed and many older roundabouts are now priority roundabouts.
• Unmarked Roundabouts: These are rare. If a roundabout has no priority signs or road markings (no B6 sign or shark teeth), the general rule of 'right-before-left' applies. This means traffic entering from the right has priority over traffic already on the roundabout. However, these are exceptions, and most roundabouts have clear priority rules.
• Mini Roundabouts (Minirotondes): These are single-lane priority roundabouts often found at smaller intersections within built-up areas. Despite their size, the same priority rules as larger priority roundabouts apply.
• Multi-lane Roundabouts (Meerstrooksrotondes): These roundabouts have two or more lanes, requiring drivers to choose the correct lane before entering, based on their intended exit. Lane discipline is crucial to avoid sudden changes on the roundabout itself.
• Turbo Roundabouts (Turborotondes): An advanced type of multi-lane roundabout where drivers must pre-sort into specific lanes before entering the roundabout. Once on a turbo roundabout, lane changes are usually impossible due to physical separations, enhancing safety and flow. Arrows on the road surface guide drivers to the correct lane for their destination.

Priority Rules at Dutch Roundabouts

The fundamental rule for priority at a Dutch roundabout depends on the signage:

• Most Common (Priority Roundabouts): If you see a B6 sign and shark teeth on the road when approaching, you must give way to all drivers already on the roundabout. This also often includes cyclists on a dedicated cycle path around the roundabout, though this can vary by location and signage. Always check for specific signs regarding cyclists.
• Rare (Unmarked Roundabouts): If there are no signs or road markings indicating priority, the general priority rule of 'right-before-left' applies. This means traffic entering the roundabout from your right has priority. However, be vigilant, as these are increasingly uncommon.

Signaling at Roundabouts

Correct signaling is vital for safety and clear communication at roundabouts in the Netherlands:

• Exiting: It is mandatory to signal right before you leave the roundabout. This informs other road users, including those waiting to enter and cyclists, of your intention to exit.
• Entering: You do not signal when entering a roundabout.
• Going straight or turning left: While some driving instructors may teach signaling left when taking the third or fourth exit (often referred to as 'three-quarters around'), this is not legally mandatory in the Netherlands and can even be forbidden in other countries. Focus on the mandatory right signal upon exit.

Lane Usage and Positioning

When approaching a multi-lane roundabout, choosing the correct lane is crucial:

• Going straight or turning right: Generally, position your vehicle in the rightmost lane (if applicable) before entering. You will typically exit from this lane.
• Turning left (or going more than halfway around): Usually, you should use an inner lane. However, on turbo roundabouts, you must be in the correct lane before entering and maintain it until your exit. Always follow the arrows on the road surface or traffic signs for guidance.

Safety at Roundabouts

Roundabouts are generally safer than traditional intersections, but certain precautions are still necessary:

• Reduce Speed: Always approach a roundabout at a reduced speed, allowing you time to observe, assess priority, and react.
• Look Ahead and Scan: Continuously scan for other vehicles, cyclists, and pedestrians, especially those already on the roundabout or waiting to enter. Pay extra attention to your blind spots.
• Cyclists and Pedestrians: Be particularly aware of cyclists, who may have priority or be less visible. Look for zebra crossings for pedestrians.
• Avoid Abrupt Lane Changes: Plan your route and choose your lane well in advance. Avoid sudden braking or changing lanes on the roundabout itself.
• Give Space: Maintain a safe distance from the vehicle in front of you.
