Are car turn signals up-right-down-left?

[StJordan]

Car turn signals follow an up-right-down-left pattern. From the driver's perspective, up corresponds to the right turn, down corresponds to the left turn, pushing away activates the high beam, pulling closer activates the low beam, and a push-pull motion alternates between high and low beams. When observing a need to turn ahead while driving, it is essential to activate the turn signal approximately 10 seconds in advance to alert vehicles behind to take timely measures, such as slowing down, stopping, or waiting, to avoid collisions or even rear-end accidents. As signal lights, turn indicators primarily serve to inform surrounding vehicles of the driver's intended direction change during daily driving, prompting other vehicles to yield and prevent collisions. Therefore, whether turning, changing lanes, overtaking, starting, or parking, whenever the vehicle needs to steer away from its current lane, the turn signal should be activated in advance. This is a fundamental principle of safe driving.
