To enter a 3-lane roundabout, check road markings and signs first, but generally use the left lane for left turns, the right lane for right turns/U-turns, and the left or middle lane for going straight, then yield to traffic already inside and stay in your lane until you exit, signaling appropriately. Always give way to vehicles on your right, and don't change lanes inside the circle unless necessary, using indicators and checking mirrors.
3 lane roundabout rules in the UK
If you are going left, you should use the left-hand lane. Use the right-hand lane for going right. If you are going ahead, you should use the middle lane, unless road markings tell you otherwise.
Approaching a Multi-Lane Roundabout
Drivers should be ready to stop and let them safely finish. Drivers must yield to traffic in all lanes of the roundabout, not just in the lane closest to them. If large vehicles like trucks or buses are in the roundabout, drivers should give them space and avoid driving next to them inside the roundabout.
The golden rule
You approach the roundabout from the 6 o'clock position, entering the roundabout by turning left so that you go around in a clockwise direction, while at the same time, giving way to traffic coming from your right, who are already on the roundabout.
Failing to give way:
This is by far the most common mistake drivers make on roundabouts. Remember, drivers already in the roundabout have the right of way, so give way to them before entering.
As a general rule of thumb:
Three-Lane Roundabout Rules UAE
Correct roundabout procedure
Start the turn in the left lane closest to the middle of the street. To reduce the risk of collision, end the turn in the left lane closest to the middle of the street going in your vehicle's direction.
When driving on a multi-lane highway, stay in the right lane if you are driving slower than the traffic around you. The left lane is for passing only.
When reaching a roundabout you should: Always give priority to the traffic coming from the right, unless you have been directed otherwise by signs, road markings or traffic lights. Check if the road markings allow you to proceed without giving way (always look right before joining just in case)
Roundabouts Rules
If a multilane roundabout, choose your lane based on your intended exit. Watch for pedestrians and cyclists and be ready to stop at the crosswalk. Signal left or right to warn other drivers if you intend on turning at the roundabout (no signal if you plan to proceed straight through the roundabout).
The four essential rules for roundabouts are: Slow Down, Give Way to traffic already inside (including pedestrians/cyclists), Use the Correct Lane (left for left/straight, right for right/U-turn, following signs), and Signal your intention to exit by indicating left just before your exit, as noted by Transport Victoria, NSW Government, and RAC WA.
If you're taking a left turn at a roundabout (usually the 1st exit), you'll always need to approach it in the left lane. Ensure you remain in the left-hand lane for the entire time you're on the roundabout. Keep your left indicator on and leave via the first exit.
Yield to Both Lanes of Traffic
If you plan to turn right, stay in the farthest right lane and wait for approaching cars to pass before entering the roundabout.
Vehicles that are inside and circulating through the roundabout always have the right of way. Motorists or bicyclists who want to enter the roundabout must yield to all lanes and wait for a safe gap in circulating traffic to enter the roundabout.
Avoid failure to yield
To proceed into the roundabout, entering drivers must yield to all traffic from the left, waiting until all traffic from the left is clear. Entering drivers are not permitted to enter alongside cross traffic, because both lanes of cross traffic are allowed to exit the roundabout.
Failure to Yield: Failure to yield is the most common cause of accidents in roundabouts. Drivers must yield to traffic that is already in the roundabout. Unfortunately, confusion or impatience often leads to errors.
Using roundabouts
When you approach a roundabout, you must slow down or stop to give way to all vehicles already in the roundabout. This means giving way to vehicles already in the roundabout on your right, and vehicles that have entered the roundabout from your left or from directly opposite you.
