Which Turn Signal to Use for Lane Change, Left or Right?

[MacAbigail]

Use the turn signal corresponding to the direction of the lane change. For example, use the left turn signal when changing to the left lane and the right turn signal when changing to the right lane. Below are more regulations on turn signal usage: 1. Left turn signal: Turn on the left turn signal in advance when making a left turn, changing to the left lane, preparing to overtake, leaving a parking spot, or making a U-turn. 2. Right turn signal: Turn on the right turn signal in advance when making a right turn, changing to the right lane, returning to the original lane after overtaking, or parking by the roadside. 3. Turn signal usage on highways: When entering a highway from an on-ramp, turn on the left turn signal and merge into the lane without obstructing the normal flow of traffic already on the highway. When exiting a highway, turn on the right turn signal, enter the deceleration lane, reduce speed, and then exit.
