Common Sense of Driving: How to Use Turn Signals When Entering a Roundabout?

[Ian]

Common sense of driving regarding the use of turn signals when entering a roundabout can be explained from three aspects: 1. Turning left in a roundabout. If the vehicle needs to turn left, the left lane inside the roundabout should be selected. Since the vehicle needs to move from the outer lane to the inner lane, the left turn signal should be activated when entering the roundabout. Before exiting the roundabout, the right turn signal should be activated in advance, and after confirming safety, the vehicle should start changing lanes from the inner lane to the outer lane, then exit the roundabout. 2. Going straight in a roundabout. If the vehicle needs to go straight, the middle lane inside the roundabout should be selected. Since the vehicle does not need to change lanes after entering the roundabout, the left turn signal is not required when entering; when preparing to exit the roundabout to continue straight, since the vehicle needs to cross the right lane inside the roundabout, the right turn signal should be activated to alert other vehicles, then exit the roundabout. 3. Turning right in a roundabout. If the vehicle needs to turn right to another intersection, the right lane inside the roundabout can be selected, or the vehicle can turn right from the outer lane of the roundabout. The situation when entering the roundabout is similar to going straight, so the left turn signal is also not required; when the vehicle selects the corresponding intersection, the right turn signal should be activated in advance, and after confirming safety, the vehicle should turn right to exit the roundabout. Typically, roundabouts are set up at intersections with multiple roads. Except for vehicles turning right, all other vehicles heading to various intersections need to enter the roundabout and go around. The roundabout is generally designed with four lanes: the left lane is for left turns, the middle two lanes are for going straight, and the right lane is for turning right to exit the roundabout.
