What Causes the Car Turn Signal to Stay On?

[LeCharlie]

Reasons why the car turn signal won't turn off: 1. Relay failure; 2. Loose wiring or short circuit. The car turn signal is the main device indicating vehicle dynamic information. The turn signal uses a flasher unit installed at the front and rear of the vehicle body, activated during turns to ensure driving safety. How to use car turn signals: 1. When entering or exiting a roundabout, activate the corresponding turn signal according to the driving direction; 2. When making a U-turn, activate the left turn signal and check for oncoming traffic from both directions before turning; 3. When pulling over, first activate the right turn signal and observe traffic conditions behind the right side of the vehicle; 4. When overtaking on roads without solid center line markings, activate the left turn signal and sound the horn.
