What is the upward turn signal?

[JuliannaRose]

Upward is the right turn signal. The functions of turn signals are: 1. To indicate to pedestrians or other vehicles the direction of the turn; 2. To show the direction for overtaking and lane changing; 3. When both left and right turn signals are on simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to be cautious. Precautions for using turn signals include: 1. Activate the turn signal in advance before making a turn; 2. Use the left turn signal when overtaking and the right turn signal when returning to the original lane; 3. When activating the turn signal, observe pedestrians and passing vehicles before performing any vehicle maneuvers. Solutions for turn signal malfunctions: 1. Replace the turn signal bulb filament; 2. Reconnect the bulb to the socket; 3. Replace with a higher wattage bulb; 4. Check the turn signal wiring and perform necessary repairs.
