Do you need a blinker to turn?

According to road traffic laws and driving safety regulations, turn signals must be used when turning to clearly indicate driving intentions. When turning left or making a U-turn, the left turn signal should be activated 30 to 100 meters in advance; when turning right, the right turn signal must be engaged, and this operation should be completed 10 to 20 seconds before entering the designated lane. When changing lanes, the corresponding turn signal should be activated 3 to 5 seconds in advance, and the manoeuvre should only be executed after ensuring safety by checking the rearview mirror. The control locations for turn signals may vary across vehicle models (e.g., the lever on the left side of the steering column or overhead buttons), but generally follow the "up-right, down-left" principle, and drivers should thoroughly familiarize themselves with the vehicle's manual specifications. Non-compliance with turn signal regulations may incur fines and penalty points, whereas proper usage can reduce lane-changing accident risks by approximately 40%.
