Under what circumstances are rear position lights turned on?

Rear position lights are tail lights, which are the lights that come on when braking. Generally, when the following vehicle is too close, you can use continuous light braking to remind the rear vehicle to maintain a safe distance. Hazard warning lights flashing: To alert other vehicles that your car is malfunctioning and may brake suddenly, informing them to keep a distance; due to weather conditions or road maintenance, turn on the hazard lights in advance to alert following vehicles to pay attention to speed; in case of accidents or malfunctions, turn on the hazard lights promptly to warn oncoming vehicles to avoid. Headlight flashing: To signal an oncoming vehicle to switch from high beams to low beams for safer passing. To alert the driver ahead that there is an issue with their car, such as an unclosed door, unclosed trunk, incorrect tire pressure, etc.; three flashes of headlights in response are usually considered as a gesture of thanks from the driver.
Rear position lights are primarily turned on when there is insufficient light, especially when driving at night. Once it gets dark, the tail lights must be switched on so that vehicles behind can clearly see your position. During rainy days or when there is heavy fog with low visibility, turning on the rear position lights is particularly important to reduce the risk of rear-end collisions. Additionally, on overcast days or when entering tunnels, the lights should also be activated, as it makes your vehicle more noticeable to others. In most countries, it is legally required to turn on the rear position lights after sunset or during adverse weather conditions; otherwise, you may receive a fine. I always make it a habit to check if the lights are functioning as soon as I get in the car, replacing any burnt-out bulbs promptly. Safety comes first—this small detail can protect both others and yourself, especially on highways.
