What are the turn signal requirements for a 90-degree turn?

[JaylaLynn]

The turn signal requirement for a 90-degree turn is to signal in advance. Below are the relevant details about navigating a 90-degree turn: Follow the principle of 'left-side entry, right-side exit': This principle ensures that the right side of the vehicle is farther from the roadside when entering the turn, preventing the right rear wheel from touching the curb due to the influence of the inner wheel difference during the 1.5-turn steering maneuver to the right. Maintain vehicle movement while steering: When turning the steering wheel 2 turns to the left, ensure the vehicle is in motion. Turning at an extremely low speed or almost stationary may cause the left rear wheel to hit the curb upon exiting. Additionally, these two turns should not be executed too quickly, as this could also lead to the left rear wheel touching the roadside.
