Is the turn signal always on the left?

The switch for a car's turn signals is usually located on the control lever below the left side of the steering wheel. The operation follows the universal design of "up for right, down for left"-pushing up activates the right turn signal, while pulling down activates the left one. The turn signals themselves are installed on the front and rear sides of the vehicle and near the left and right side mirrors. Their core component, the flasher, comes in three types: thermal (bimetallic strip), capacitor, and electronic, ensuring stable and reliable signals. When using turn signals, attention should be paid to timing and specifications: activate them 10 seconds before changing lanes or turning; engage them 30 to 10 meters in advance when turning at intersections; use the right signal when pulling over to park and the left signal when pulling away; and select the corresponding signal based on the direction of travel at roundabouts. The design of turn signals, with standardized positions and clear light signals, aims to effectively reduce traffic accidents caused by insufficient communication, making them an indispensable part of the road safety system.
