Should the left turn signal be used when overtaking without changing lanes on the highway?

[ThomasLynn]

When overtaking without changing lanes on the highway, it is not necessary to use the left turn signal. Below are some precautions for driving on the highway: 1. Overtaking: Be extremely cautious when overtaking on the highway. Always use the turn signal before overtaking, and overtake from the overtaking lane. Avoid developing the bad habit of overtaking from the right side. After signaling, do not overtake immediately; also pay attention to the road conditions behind you. When conditions permit, accelerate and maintain a lateral distance of 1.5 meters from the vehicle in front. 2. Maintaining longitudinal distance between vehicles: Generally, on dry roads with good braking conditions, the distance between vehicles (in meters) should not be less than the speed (in km/h). For example, at a speed of 80 km/h, the distance should not be less than 80 meters, and at 100 km/h, it should not be less than 100 meters. Always pay attention to roadside distance markers.
