How many seconds after turning on the turn signal can you change lanes?

[VanAugust]

Generally, you can change lanes after three seconds. The timing is not the key point; the important thing is to check the rearview mirror first and ensure that the lane change does not affect the normal driving of the vehicle behind. Below is relevant information: 1. Turn signal: The turn signal is an important indicator light that is turned on when a motor vehicle changes direction to alert surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a microcontroller circuit, with alternating left and right flashing in continuous operation. The turn signal employs a flasher to achieve the blinking effect, mainly categorized into resistance-wire type, capacitor type, and electronic type. 2. Precautions: Changing lanes after three seconds allows the driver to better confirm the rationality of the lane change timing and gives vehicles behind time to prepare for avoidance. Completing the lane change within 10 seconds not only reduces the probability of unexpected situations during the process but also minimizes driving risks, as prolonged lane changes increase the danger coefficient.
