When turning, activate the corresponding turn signal based on the direction: push the control lever downward for a left turn signal and upward for a right turn signal. This action should be performed approximately 30 to 100 meters in advance to ensure other road users have adequate reaction time. For instance, when changing lanes, activate the signal at least 3 seconds beforehand and verify safety by checking the rearview mirror. In specific scenarios like overtaking, first engage the left turn signal; when returning to the original lane after completing the manoeuvre, switch to the right turn signal. For U-turns, consistently use the left turn signal. Ensure the turn signal's flashing frequency is normal, avoid activating it too early or too late, and promptly deactivate it after completing the action. Proper use of turn signals significantly reduces traffic accidents and is an essential safety practice every driver must master.
