What Is a Roundabout?

A roundabout is a circular intersection where traffic flows counterclockwise around a central island. Unlike traditional intersections, roundabouts are designed to reduce the likelihood of high-speed collisions by requiring vehicles to slow down and yield before entering.

In California, roundabouts help:

• Improve traffic flow by eliminating stop signs and traffic signals.
• Reduce crash severity by lowering speeds.
• Decrease delays by promoting continuous movement.

California Laws and Rules for Roundabouts

According to the California Driver Handbook, drivers must adhere to specific rules when approaching and navigating roundabouts. Key guidelines include:

1. Yielding to Traffic: Drivers must yield to all vehicles already in the roundabout before entering.
2. Correct Lane Use: Stay in the appropriate lane for your destination before entering the roundabout.
3. Speed Control: Reduce speed when approaching and while driving through the roundabout.
4. No Stopping: Never stop within the roundabout unless to avoid a collision.
5. Signaling Exits: Use your right turn signal before exiting the roundabout.

Step-by-Step Guide on How to Drive in a Roundabout in California

1. Approach the Roundabout Carefully

As you approach a roundabout, slow down and watch for signs that indicate lane designations and speed limits. Look for:

• Yield signs, which mean you must give way to traffic inside the roundabout and pedestrians.
• Lane markings, guiding you to the correct lane based on your intended exit.

Tip: Choose your lane early and avoid last-minute lane changes.

2. Yield to Traffic in the Roundabout

One of the most crucial aspects of understanding how to drive in a roundabout in California is yielding. Drivers must always yield to:

• Vehicles already circulating in the roundabout.
• Pedestrians and cyclists at designated crosswalks.

Wait for a safe gap in traffic before entering. Never force your way into the roundabout, as this can lead to accidents and traffic citations.

3. Enter the Roundabout Safely

Once a safe gap appears, enter the roundabout while maintaining a low speed (typically 15–25 mph, as recommended by California road signs). Keep in mind:

• Vehicles inside the roundabout have the right-of-way.
• Stay within your lane and avoid drifting.
• Look ahead to your intended exit to stay on track.

4. Navigate the Roundabout

While inside the roundabout, maintain a steady speed and stay aware of other vehicles. Follow these key tips:

• Keep to your lane: Lane discipline is essential in multi-lane roundabouts to avoid collisions.
• Avoid sudden braking: Maintain smooth movement unless an emergency requires stopping.
• Stay alert for exits: Know your exit in advance to avoid last-minute maneuvers.

5. Exit the Roundabout Safely

Before exiting the roundabout, signal right to indicate your intention to other drivers and pedestrians. As you exit:

• Check your mirrors: Ensure there are no vehicles or pedestrians in your blind spot.
• Yield to pedestrians: If a crosswalk is present, let pedestrians cross before proceeding.
• Resume normal speed: Once you’ve safely exited, gradually increase your speed.

Common Mistakes When Driving in a Roundabout

Even experienced drivers can make mistakes when learning how to drive in a roundabout in California. Here are some common errors to avoid:

1. Failing to Yield: Entering the roundabout without waiting for a safe gap can lead to collisions.
2. Lane Changing Inside the Roundabout: Changing lanes within the circle is dangerous and can confuse other drivers.
3. Stopping Inside the Roundabout: Unless necessary, stopping disrupts traffic flow and increases accident risk.
4. Not Using Turn Signals: Failing to signal your exit can cause confusion for other road users.
5. Driving Too Fast: Excessive speed reduces reaction time and increases the risk of losing control.

Roundabout Right-of-Way Rules in California

To comply with California traffic laws, understanding the right-of-way rules is critical:

• Vehicles inside the roundabout always have the right-of-way.
• Pedestrians and cyclists crossing at designated points must be given priority.
• Emergency vehicles always take precedence; pull over before entering if necessary.

Failing to yield correctly can result in fines or points on your driving record under the California Vehicle Code Section 21800-21804, which covers intersection and right-of-way regulations.

Different Types of Roundabouts in California

California features several types of roundabouts, and each may require a slightly different driving approach:

1. Single-Lane Roundabouts: These are the most common and easiest to navigate. Simply yield, enter, and exit smoothly.
2. Multi-Lane Roundabouts: Require careful lane selection before entry. Ensure you’re in the correct lane for your intended exit.
3. Mini Roundabouts: Found in residential areas, these require slower speeds and caution with nearby pedestrians.
4. Traffic-Calming Circles: These are designed to slow down traffic in suburban neighborhoods and should be treated similarly to roundabouts.
