Which turn signal to use when merging into traffic?
2 Answers
When merging into traffic from the right to the left lane, always use the left turn signal. Function of turn signals: As signal lights, turn signals primarily serve to alert surrounding vehicles during daily driving, indicating an upcoming turn or lane change so that other vehicles can yield and avoid collisions. Whenever a vehicle needs to steer away from its current lane, the turn signal should be activated in advance—this is a fundamental principle of safe driving. How turn signals work: The turn signal bulb uses a xenon tube, controlled by a single-chip microcomputer circuit, which operates with an alternating left-right flashing pattern without interruption. When a certain voltage or current is applied to the electromagnetic relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, yoke, armature, and working air gap.
When I first started learning to drive, I was quite confused about which turn signal to use when merging into traffic. I remember that time when I started from the roadside in the city, I panicked and turned on the right signal, and the car next to me almost rushed up, which really scared me. The instructor quickly corrected me, saying that in countries where you drive on the right, you must use the left turn signal when merging. It clearly indicates that you are moving left into the lane, letting the following cars know your intention. Developing this habit can reduce blind spot accidents, especially at highway entrances or during traffic jams. After signaling, don’t forget to check the rearview and side mirrors to confirm a safe distance. When driving, I often remind my friends that although the turn signal is just a small button, it can be life-saving at critical moments—never skip it out of laziness. Some people have the habit of cutting in without signaling, which can easily provoke road rage. Putting safety first is always the wise choice.
