Should You Use Turn Signals When Changing Lanes While Driving?

[MasonLee]

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.
