The golden rules for using car lights can be summarized as "timely switching, avoiding interference, and clear signaling", with the core principle being to select the appropriate lighting combination according to varying road conditions and environments to ensure driving safety. Turn signals must be activated at least 3 seconds before turning, changing lanes, overtaking, or pulling over. The left turn signal indicates left turns or U-turns, while the right turn signal is for right turns or merging back to the original lane - this is crucial for communicating driving intentions. When approaching oncoming traffic, switch to low beams at least 150 meters away; this rule also applies on narrow roads or when encountering non-motorized vehicles. In special situations like sharp curves, steep grades, or uncontrolled intersections, drivers should alternately flash their high and low beams as a warning. Fog lights should only be used in severe weather conditions, as their intense penetration makes them unsuitable for regular illumination. Hazard warning flashers (emergency lights) are strictly for breakdown stops, accidents, towing situations, or when highway visibility drops below 100 meters - improper use may confuse other road users. Violations of lighting regulations may incur penalty points, such as failing to properly use turn signals or incorrect high-beam usage. Proper light operation not only enhances a driver's visibility but significantly reduces accident risks, constituting an essential safety protocol all drivers must master.
