Why don't you use turn signals when simulating turns with lights?

[Sue]

Because the penetrating power of turn signals is relatively strong, which can easily affect the vision of drivers in front and behind at night. The mnemonic for light simulation is as follows: Headlights - driving at night without streetlights or under poor lighting conditions. Low beam - meeting non-motor vehicles on narrow roads at night, following vehicles closely in the same direction at night, meeting motor vehicles at night. High-low beam alternation - passing bridges, crosswalks at night, passing sharp curves and slopes at night, passing intersections without traffic lights at night. Width markers and hazard warning lights - vehicle breakdown on the road at night that obstructs traffic and is difficult to move, driving in foggy weather.
