Should You Use Turn Signals When Changing Lanes While Driving?

You should use turn signals when changing lanes while driving. The purpose of using turn signals is to alert other vehicles that your car is preparing to change lanes. When to activate turn signals: Turn signals should be activated when the vehicle is turning to notify surrounding vehicles and pedestrians. The timing of activating turn signals is important—they should be turned on approximately 10-30 meters before reaching a turn and 5 seconds in advance when changing lanes. Scenarios requiring turn signal usage: Left turn signals should be activated in advance when making a left turn, changing to the left lane, preparing to overtake, leaving a parking spot, or making a U-turn. Right turn signals should be activated in advance when making a right turn, changing to the right lane, returning to the original lane after overtaking, or parking by the roadside.
Of course you should use the turn signal! I remember when I first started driving, I thought it was okay to change lanes without signaling, and I almost got into an accident. I suddenly changed lanes on the highway without warning, and the car behind me almost rear-ended me—it was terrifying. Since then, I’ve learned my lesson: using the turn signal is like telling others where you’re going, as simple and essential as a greeting. Chinese traffic laws clearly require using turn signals when changing lanes—it’s a legal baseline. Failing to do so can result in points deducted, fines, or even serious accidents. Forming the habit is easy: check the rearview mirror first, flash the signal for a few seconds, check the blind spot, and then turn the wheel. Especially in rain or at night when visibility is poor, signaling early gives others time to react and avoids chain collisions. Driving isn’t a game—every bit of safety comes from these small details. I do this every day now, and it feels like everyone on the road is friendlier.
