Why Turn on the Right Turn Signal When Exiting a Roundabout?

[SaraMarie]

Motor vehicles do not need to turn on the turn signal when entering a roundabout, but they must activate the right turn signal when exiting the roundabout to alert following vehicles. This is because entering the roundabout does not affect other vehicles, while exiting the roundabout involves an unpredictable exit point, necessitating the use of the turn signal for indication. Typically, roundabout exits consist of two lanes, with vehicles generally driving on the right side, hence the need to use the right turn signal. 1. General Scenario: Roundabouts are usually set up at intersections with multiple roads (three or more), where vehicles heading to all other roads except those turning right must enter the roundabout to navigate. 2. Additional Information: Article 51 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates that motor vehicles passing through signal-controlled intersections shall proceed as follows: At intersections with marked guide lanes, enter the guide lane according to the intended direction of travel; vehicles preparing to enter the roundabout must yield to vehicles already inside the roundabout.
