Is it necessary to use turn signals for a right-angle turn?

[ConnorFitz]

Turn signals are not required for a right-angle turn. Here is some information about turn signals: Introduction: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert vehicles and pedestrians in front, behind, and to the sides. Turn signals: When a vehicle approaches a flat intersection, the turn signal should be activated in the direction of the turn approximately 3 meters before the intersection. When entering or exiting a roundabout, the turn signal should be activated according to the direction of travel. While driving, if the traffic in the current lane is congested and a lane change is necessary, the driver should check the adjacent lane for availability via the rearview mirror. Without obstructing the normal flow of traffic in other lanes, the corresponding turn signal should be activated before changing lanes. When making a U-turn, the left turn signal should be activated, and the driver should observe whether there are any oncoming vehicles before proceeding with the turn.
