Should I look at the front or left signal light when turning left?

[AbelMarie]

When there is a dedicated left-turn traffic light, proceed when it turns green. If there is no dedicated left-turn signal, you may turn left when the straight-through light turns green. Precautions for using turn signals are as follows: 1. While driving: When traffic in your lane is congested and you need to change lanes, check adjacent lanes via the rearview mirror. If the lane is clear and you won't obstruct other vehicles, first activate the corresponding turn signal before changing lanes. 2. When making a U-turn: Activate the left turn signal and check for oncoming traffic in front and behind before turning. 3. Honking: On roads without solid center lines, when overtaking, activate the left turn signal and honk. If being overtaken, move right to yield. 4. When pulling over: First activate the right turn signal, observe traffic conditions behind you, then pull over. 5. When leaving a parking spot: First activate the left turn signal, check traffic behind you, then merge into the traffic lane.
